1. INTRODUCTION The RCM5700 and RCM6700 are compact modules in a mini PCI Express form factor, and incorporate the powerful Rabbit® 5000 and 6000 microprocessors with integrated 10/100Base-T Ethernet functionality and onchip SRAM. The Rabbit® 5000 and 6000 microprocessor features include hardware DMA, I/O lines shared with up to six serial ports and four levels of alternate pin functions that include variable-phase PWM, an external I/O bus, quadrature decoder, and input capture.
1.1 RCM5700/RCM6700 Features • Small size: ranges from 1.20" × 2.00" × 0.12" (30 mm × 51 mm × 3 mm) for the RCM5700/ RCM6700 model to 1.20" × 2.00" × 0.73" (30 mm × 51 mm × 19 mm) for the RCM5760/ RCM6760 model • Microprocessor: RCM5700: Rabbit 5000 running at 50.0 MHz RCM6700: Rabbit 6000 running at 187.5 MHz • Up to 35 general-purpose I/O lines each configurable with up to four alternate functions • 3.
The RCM5700 and RCM5750 models already have an Ethernet PHY device, the Integrated Circuit Systems ICS1893BK. The RCM5710 and RCM5760 are identical to the RCM5700 and RCM5750 respectively, except that they have an integrated 10/100 Base-T magnetic RJ-45 jack with two LEDs on the MiniCore printed circuit board. There are four RCM6700 production models. Table 1-2 summarizes their main features. Table 1-2.
All RCM5700/RCM6700 models are programmed through a USB connector on the motherboard using a USB cable supplied with the Development Kit. The RCM5750/RCM5760 may also be programmed remotely over an Ethernet link using the Remote Program Update library with Dynamic C v. 10.56 or later. The RCM67xx series may also be used with the Remote Program Update with Dynamic C v. 10.64 or later. See Application Note AN421, Remote Program Update, for more information.
1.3 Development and Evaluation Tools 1.3.1 Standard Development Kit The RCM5700/RCM6700 Standard Development Kit contains the hardware essentials you will need to use your RCM5700 or RCM6700 module. These items are supplied in the standard version of the Development Kit. • RCM5700 or RCM6700 module. • Interface Board with standoffs/connectors. • Prototyping Board with standoffs/connectors. • USB cable to program MiniCore via Interface Board. • Dynamic C CD-ROM, including product documentation on disk.
1.3.3 Software The RCM5700/RCM5710 is programmed using version 10.44 or later of Dynamic C; the RCM5750/RCM5760 requires version 10.56 or later of Dynamic C; and the RCM6700 family requires version 10.64 or later. A compatible version is included on the Development Kit CD-ROM. In addition to the Web-based technical support included at no extra charge, a one-year telephonebased technical support subscription is also available for purchase.
2. GETTING STARTED This chapter describes the RCM5700/RCM6700 hardware in more detail, and explains how to set up and use the accompanying Interface Board. NOTE: This chapter (and this manual) assume that you have the RCM5700/RCM6700 Development Kit. If you purchased an MiniCore module by itself, you will have to adapt the information in this chapter and elsewhere to your test and development setup. 2.
2.2 Hardware Connections There are three steps to connecting the Interface Board for use with Dynamic C and the sample programs: 1. Insert standoffs/connectors on the Interface Board. 2. Install the MiniCore module on the Interface Board. 3. Connect the USB cable between the Interface Board and the workstation PC. 2.2.
2.2.2 Step 2 — Install Module on Interface Board Position the MiniCore module with the edge connectors facing the mini PCI Express socket J1A at an angle as shown in Figure 2-3 below. Insert the edge connectors into the mini PCI Express socket J1A, then press down on the opposite edge of the MiniCore module to snap it into place in holder J1B. Figure 2-3. Install the MiniCore Module on the Interface Board MiniCore RCM5700/RCM6700 User’s Manual rabbit.
Should you need to remove the MiniCore module, use two fingernails to hold back the spring clip at J1B from the two MiniCore corners, lift up the edge of the MiniCore above J1B, then pull the MiniCore away to remove the edge connectors from the mini PCI Express socket. CAUTION: Remove power before attempting to insert or remove the MiniCore in the mini PCI Express socket. MiniCore RCM5700/RCM6700 User’s Manual rabbit.
2.2.3 Step 3 — Connect USB Cable The USB cable connects the RCM5700/RCM6700 to the PC running Dynamic C to download programs and to monitor the MiniCore module during debugging. It also supplies power to the Interface Board and the MiniCore via the USB interface. Connect the USB cable between USB connector J5 on the Interface Board and your PC as shown in Figure 2-4.
2.2.3.1 Alternate Power Supply Connections — Deluxe Development Kit The deluxe Development Kit contains a separate AC adapter that may be used to supply power to the Interface Board and the RCM5700/RCM6700 when the USB cable is not connected or when more power is needed than the 500 mA the USB cable is able to supply. The AC adapter may also be used to supply power when the USB cable is connected, in which case the power supply through the USB cable will be disconnected automatically. Figure 2-5.
2.3 Starting Dynamic C If you already have Dynamic C installed, you are now ready to test your programming connections by running a sample program. Start Dynamic C by double-clicking on the Dynamic C icon on your desktop or in your Start menu. Select Store Program in Flash on the “Compiler” tab in the Dynamic C Options > Project Options menu. Then click on the “Communications” tab and verify that Use USB to Serial Converter is selected to support the USB cable. Click OK.
2.5 Where Do I Go From Here? If the sample program ran fine, you are now ready to go on to other sample programs and to develop your own applications. The source code for the sample programs is provided to allow you to modify them for your own use. The RCM5700/RCM6700 User’s Manual also provides complete hardware reference information for the RCM5700/RCM6700, the Interface Board, the Prototyping Board, and the accessory boards in the Deluxe Development Kit.
3. RUNNING SAMPLE PROGRAMS To develop and debug programs for the RCM5700/RCM6700 (and for all other Rabbit hardware), you must install and use Dynamic C. This chapter provides a tour of its major features with respect to the RCM5700/RCM6700. 3.1 Introduction To help familiarize you with the RCM5700/RCM6700 modules, Dynamic C includes several sample programs.
3.2 Sample Programs Of the many sample programs included with Dynamic C, several are specific to the RCM5700/RCM6700. These programs will be found in the SAMPLES\RCM5700 or SAMPLES\RCM6700 folder, depending on your MiniCore model. Sample programs in the SAMPLES folder one level up are generally generic samples that can be run on any Rabbit-based product Before you compile and run the following sample programs, make sure that pins 1–2, 5–6, and 7– 8 on header JP1 of the Interface Board are jumpered.
The Digital I/O accessory board needs to be installed to run the SWITCHLEDS.C and the SERIALTOSERIAL.C sample programs. This accessory board is included only with the Deluxe Development Kit. To install the Digital I/O accessory board, insert the strip of header pins included with the accessory board into the socket at J12 on the bottom side of the Digital I/O accessory board.
The SERIALTOSERIAL.C sample program is in the SAMPLES\RCM5700\SERIAL or SAMPLES\RCM6700\SERIAL folder, depending on your MiniCore model. • SERIALTOSERIAL.C—monitors switches S1, S2, S3, and S4 on the Digital I/O accessory board and lights LEDs DS1–DS4 when the corresponding pushbutton switch is pressed. LEDs DS1–DS2 on the Digital I/O accessory board are controlled by PA4–PA7, and switches S1–S4 are controlled by PB4–PB7 respectively.
The Serial Communication accessory board needs to be installed to run the following serial sample program in the SAMPLES\RCM5700\SERIAL or SAMPLES\RCM6700\SERIAL folder, depending on your MiniCore model. This accessory board is included only with the Deluxe Development Kit. To install the Serial Communication accessory board, insert the strip of header pins included with the accessory board into the socket at J12 on the bottom side of the Serial Communication accessory board.
Once you have loaded and executed these sample programs and have an understanding of how Dynamic C and the RCM5700/RCM6700 modules interact, you can move on and try the other sample programs, or begin developing your own application. 3.2.1 Use of Serial Flash (not supported for RCM5700/RCM5710) The following sample programs from the SAMPLES\RCM5700\Serial_Flash folder may be used with the RCM5750/RCM5760 models. • SERIAL_FLASHLOG.
4. HARDWARE REFERENCE Chapter 4 describes the hardware components and principal hardware subsystems of the RCM5700/RCM6700. Appendix A, “RCM5700/RCM6700 Specifications,” provides complete physical and electrical specifications. Figure 4-8 shows the Rabbit-based subsystems designed into the RCM5700/RCM6700. Figure 4-8. RCM5700/RCM6700 Subsystems MiniCore RCM5700/RCM6700 User’s Manual rabbit.
4.1 RCM5700/RCM6700 Digital Inputs and Outputs Figure 4-9 shows the RCM5700/RCM6700 pinouts for the edge connector. Figure 4-9. RCM5700/RCM6700 Pinouts The edge connectors are designed to interface with a 52-pin mini PCI Express socket. Pin 8 has different functionality between the RCM5700 and RCM6700, due to differences in the Ethernet PHY designs. On the RCM5700, it is the activity LED signal, while on the RCM6700 it is +2.5V for the Ethernet interface. MiniCore RCM5700/RCM6700 User’s Manual rabbit.
Figure 4-10 shows the use of the Rabbit 5000/6000 microprocessor ports in the RCM5700/ RCM6700 modules. Figure 4-10. Use of Rabbit 5000/6000 Ports The ports on the Rabbit microprocessor used in the RCM5700/RCM6700 are configurable, and so the defaults can be reconfigured. Table 4-3 lists the Rabbit factory defaults and the alternate configurations. MiniCore RCM5700/RCM6700 User’s Manual rabbit.

4.1.1 Memory I/O Interface The Rabbit 5000 address lines (A0–A19) and data lines (D0–D7) are routed to the onboard flash memory chip. I/O write (/IOWR) and I/O read (/IORD) are available for interfacing to external devices. Parallel Port A can also be used as an external I/O data bus to isolate external I/O from the main data bus. Parallel Port B pins PB2–PB7 can also be used as an external address bus.
4.2 Serial Communication The RCM5700/RCM6700 board does not have any serial level converters directly on the board. However, an Ethernet or other serial interface may be incorporated on the board the MiniCore is mounted on. For example, the Serial Communication accessory board in the Deluxe Development Kit has an RS-232 transceiver, and the Interface Board has Ethernet and USB connections. 4.2.1 Serial Ports There are six serial ports designated as Serial Ports A, B, C, D, E, and F.
Table 4-4 summarizes the possible parallel port pins for the serial ports and their clocks. Table 4-4.
4.2.2 Ethernet PHY All RCM5700/RCM6700 models have an Ethernet PHY, which can either be accessed through the Interface Board or directly on the RCM5710/5760/6710/6760. The PHY connections or integrated 10/100Base-T connections on MiniCores with an on-board RJ-45 jack are via 0 jumpers on headers JP2–JP5 (see Table A-6 in Appendix A.3). Rabbit’s Technical Note TN266, PCB Layout for the Ethernet PHY Interface, provides further details about designing your own PHY interface.
4.3 Programming Modes The USB cable is used to connect the programming port of the RCM5700/RCM6700 to a PC USB port via the Interface Board. Whenever the MiniCore is reset, the operating mode is determined by the state of the SMODE pins. The MiniCore is automatically in Program Mode when the SMODE pins, which are tied together, are pulled up to +3.3 V. This happens when the MiniCore is installed on the Interface Board, and pins 1–2 on header JP1 on the Interface Board are jumpered.
4.3.1 Standalone Operation of the RCM5700/RCM6700 The RCM5700/RCM6700 must be programmed via the Interface Board or via a similar arrangement on a customer-supplied board. Once the MiniCore has been programmed successfully, reset the MiniCore. The MiniCore may be reset by cycling power off/on or by pressing the RESET button on the Interface Board. The jumper across pins 1–2 on header JP1 on the Interface Board must be removed in order for the MiniCore to operate in the Run Mode after it is reset.
4.5 Memory 4.5.1 RAM RCM5700 boards have 128KB of onchip SRAM on the Rabbit 5000 microprocessor. The RCM5750/RCM5760 models also have 512KB of external SRAM. RCM6700 boards have 1MB of onchip RAM and 32KB of onchip battery-backable SRAM on the Rabbit 6000 microprocessor. The RCM6750/6760 models also have 1MB of external SRAM. 4.5.2 Program Flash Memory All RCM5700 models have 1MB of parallel flash memory installed at U3.
5. SOFTWARE REFERENCE Dynamic C is an integrated development system for writing embedded software. It runs on a Windows-based PC and is designed for use with single-board computers and other devices based on the Rabbit microprocessor. Chapter 5 describes the libraries and function calls related to the RCM5700/RCM6700. 5.1 More About Dynamic C Dynamic C has been in use worldwide since 1989. It is specially designed for programming embedded systems, and features quick compile and interactive debugging.
Dynamic C has a number of standard features. • Full-feature source and/or assembly-level debugger, no in-circuit emulator required. • Royalty-free TCP/IP stack with source code and most common protocols. • Hundreds of functions in source-code libraries and sample programs: Exceptionally fast support for floating-point arithmetic and transcendental functions. RS-232 and RS-485 serial communication. Analog and digital I/O drivers. I2C, SPI, GPS, file system. LCD display and keypad drivers.
5.2 Dynamic C Function Calls 5.2.1 Digital I/O The RCM5700/RCM6700 was designed to interface with other systems, and so there are no drivers written specifically for the Rabbit 5000/6000 I/O. The general Dynamic C read and write functions allow you to customize the parallel I/O to meet your specific needs. For example, use WrPortI(PEDDR, &PEDDRShadow, 0x00); to set all the Port E bits as inputs, or use WrPortI(PEDDR, &PEDDRShadow, 0xFF); to set all the Port E bits as outputs.
5.2.4 RCM5700/RCM6700 Cloning The RCM5700/RCM6700 does not have a programming header, and is programmed through the USB connection on the Interface Board. Rabbit’s Cloning Board does not support cloning through a USB connection. If there is a need to copy programs, the Rabbit Field Utility can be used to download compiled Dynamic C .bin files. 5.2.5 TCP/IP Drivers The TCP/IP drivers are located in the LIB\Rabbit4000\TCPIP folder.

It is recommended that you allow for an “exclusion zone” of 0.08" (2 mm) around the RCM5700/RCM6700 top and bottom and 0.04" (1 mm) around the three non-connector edges when the RCM5700/RCM6700 is incorporated into an assembly that includes other printed circuit boards. This “exclusion zone” that you keep free of other components and boards will allow for sufficient air flow, and will help to minimize any electrical or electromagnetic interference between adjacent boards.

A.1.1 mini PCI Express Connector Design Recommendations The MiniCore is mounted on the Interface Board via a mini PCI Express connector and a corresponding locking latch connector. These are offered by manufacturers as a matched set, although in some cases different manufacturer’s parts may be interchangeable. Table A-3 lists the recommended parts for the mini PCI Express connector and the locking latch connector used for the Interface Board.
Other manufacturers such as Molex offer similar connectors and latches, but these can have different mechanical structures and PCB footprints to what we use on the Interface Board. Table A-4 lists a pair of matched Molex parts that might be used. Table A-4.
Table A-5. Standoff Heights Based on mini PCI Express Connectors mini PCI Express Connector Height Standoff Height Remarks 6.8 mm 4.4 mm Used with Interface Board 9.2 mm 6.8 mm Used with Accessory Kit The SMT connectors are ideal in a development environment, where the latch connector facilitates swapping MiniCore modules as development progresses. The absence of holes also maximizes trace routing flexibility on the printed circuit board.
A.3 Jumper Configurations Figure A-5 shows the header locations used to configure the various RCM5700/RCM6700 options via jumpers. Note that some early versions of the RCM5700 model sold in 2008 and 2009 do not have jumper locations JP2–JP5 — this does not affect the functionality of the RCM5700 model. Figure A-5.

APPENDIX B. INTERFACE BOARD Appendix B describes the features and accessories of the Interface Board, and explains the use of the Interface Board to demonstrate the RCM5700 and RCM6700. The Interface Board has power-supply connections and a USB interface to program either MiniCore module. MiniCore RCM5700/RCM6700 User’s Manual rabbit.
B.1 Introduction The Interface Board included in the Development Kit makes it easy to connect MiniCore module to a power supply and a PC workstation for development. It also provides an Ethernet port. The Interface Board is shown below in Figure B-1, with its main features identified. Figure B-1. Interface Board MiniCore RCM5700/RCM6700 User’s Manual rabbit.
B.1.1 Interface Board Features • Power Connection—Power is supplied to the Interface Board either from the PC via the USB connection or through a power supply jack, J6. A chip at U4 disconnects the USB power supply from the rest of the Interface Board when power is supplied through jack J6 Users providing their own power supply should ensure that it delivers +5 V DC at 10 W. • Regulated Power Supply—The raw DC voltage is routed to a 3.3 V linear regulator.
B.2 Mechanical Dimensions and Layout Figure B-2 shows the mechanical dimensions and layout for the Interface Board. All measurements are in inches followed by millimeters enclosed in parentheses. Figure B-2. Interface Board Dimensions Table B-1 lists the electrical, mechanical, and environmental specifications for the Prototyping Board. Table B-1. Interface Board Specifications Parameter Specification Board Size 2.50" × 3.75" × 0.
B.2.1 Headers The Interface Board has a header socket at J2 for physical connection to other boards. J2 is a 2 × 25 SMT header socket with a 0.1" pin spacing. Figure B-3 shows the layout of another board to be plugged into the Interface Board — this footprint is identical for the Prototyping Board and the two accessory boards. The values are relative to the mounting hole. Figure B-3. Interface Board Footprint. (All measurements are in inches followed by millimeters enclosed in parentheses.
B.3 Ethernet B.3.1 RJ-45 The Ethernet filter circuit is different between the Rabbit 5000 and Rabbit 6000 Ethernet designs. If an RJ-45 jack is present on the MiniCore, then the appropriate circuitry is on the MiniCore. If the interface board Ethernet RJ-45 is to be used, then a given interface board will support Ethernet only for either the RCM5700 or RCM6700 family, but not both. The interface board supplied in the Development Kit is properly configured for the MiniCore in the kit. B.3.
B.4 Power Supply The MiniCore requires a regulated 3.15 V – 3.45 V DC power source to operate. Depending on the amount of current required by the application, different regulators can be used to supply this voltage. The Interface Board has an onboard +3.3 V linear regulator. The Interface Board is protected against reverse polarity by a Shottky diode at D3 as shown in Figure B-4. Figure B-4.
B.5 Using the Interface Board The Interface Board is also a demonstration board. It can be used to demonstrate the functionality of the MiniCore right out of the box without any modifications to either board. The Interface Board comes with the basic components necessary to demonstrate the operation of the MiniCore. One LEDs (DS1) is connected to PD0, and one switch (S1) is connected to PD1 to demonstrate the interface to the Rabbit microprocessor. Reset switch S2 is the hardware reset for the MiniCore.
B.5.1 Add Additional Boards The Prototyping Board and the two accessory boards included with the Deluxe Development Kit may be installed on the Interface Board as shown in Figure B-6. Figure B-6. Install Additional Boards on Interface Board 1. Insert the header strip into header socket J2 on the Interface Board or the board already installed above the Interface Board. 2.

APPENDIX F. USING THE TCP/IP FEATURES F.1 TCP/IP Connections Programming and development can be done with the MiniCore without connecting the Ethernet port to a network. However, if you will be running the sample programs that use the Ethernet capability or will be doing Ethernet-enabled development, you should connect the Ethernet port on the Interface Board at this time. Before proceeding you will need to have the following items.
The following options require more care in address selection and testing actions, as conflicts with other users, servers and systems can occur: • LAN — Connect the Interface Board’s Ethernet port to an existing LAN, preferably one to which the development PC is already connected. You will need to obtain IP addressing information from your network administrator.
F.2 TCP/IP Primer on IP Addresses Obtaining IP addresses to interact over an existing, operating, network can involve a number of complications, and must usually be done with cooperation from your ISP and/or network systems administrator. For this reason, it is suggested that the user begin instead by using a direct connection between a PC and the Interface Board using a CAT 4/5 Ethernet cable or a simple arrangement with a hub.
If your system administrator can give you an Ethernet cable along with its IP address, the netmask and the gateway address, then you may be able to run the sample programs without having to setup a direct connection between your computer and the MiniCore. You will also need the IP address of the nameserver, the name or IP address of your mail server, and your domain name for some of the sample programs. MiniCore RCM5700/RCM6700 User’s Manual rabbit.
F.2.1 IP Addresses Explained IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods, for example: 216.103.126.155 10.1.1.6 Each decimal number must be between 0 and 255. The total IP address is a 32-bit number consisting of the 4 bytes expressed as shown above. A local network uses a group of adjacent IP addresses. There are always 2N IP addresses in a local network. The netmask (also called subnet mask) determines how many IP addresses belong to the local network.
F.2.2 How IP Addresses are Used The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also called MAC addresses). These are 48-bit addresses and are unique for every Ethernet adapter manufactured. In order to send a packet to another computer, given the IP address of the other computer, it is first determined if the packet needs to be sent directly to the other computer or to the gateway.
F.2.3 Dynamically Assigned Internet Addresses In many instances, devices on a network do not have fixed IP addresses. This is the case when, for example, you are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or when you have a device that provides your IP addresses using the Dynamic Host Configuration Protocol (DHCP).
F.3 Placing Your Device on the Network In many corporate settings, users are isolated from the Internet by a firewall and/or a proxy server. These devices attempt to secure the company from unauthorized network traffic, and usually work by disallowing traffic that did not originate from inside the network. If you want users on the Internet to communicate with your MiniCore, you have several options.
F.4 Running TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require you to connect your PC and the MiniCore module together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet. MiniCore RCM5700/RCM6700 User’s Manual rabbit.
F.4.1 How to Set IP Addresses in the Sample Programs With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. You will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro. 1.
F.4.2 How to Set Up your Computer for Direct Connect Follow these instructions to set up your PC or notebook. Check with your administrator if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows. TIP: If you are using a PC that is already on a network, you will disconnect the PC from that network to run these sample programs.
F.5 Run the PINGME.C Sample Program Connect the crossover cable from your computer’s Ethernet port to the MiniCore module’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C. The crossover cable is connected from your computer’s Ethernet adapter to the MiniCore module’s RJ-45 Ethernet connector.
F.6 Running Additional Sample Programs With Direct Connect The sample programs discussed here are in the Dynamic C SAMPLES\RCM5700\TCPIP\ or SAMPLES\RCM6700\TCPIP folder. • BROWSELED.C—The Digital I/O accessory board must be installed with the jumpers set up as shown below to run this sample program. This program demonstrates a basic controller running a Web page. Four “LEDs” are created on the Web page, and four buttons to toggle them. Users can change the status of the lights from the Web browser.
Bits per second: 115200 Data bits: 8 Parity: None Stop bits: 1 Flow control: None As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program. http://10.10.6.100 Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. Now compile and run the sample program.
APPENDIX G. POWER SUPPLY Appendix G provides information on the current requirements of the RCM5700/RCM6700, and includes some background on the chip select circuit used in power management. G.1 Power Supplies The RCM5700/RCM6700 requires a regulated 3.15 V – 3.45 V DC power source. The MiniCore design presumes that the voltage regulator is on the user board, and that the power is made available to the RCM5700 board through the edge connectors. An RCM5700 with no loading at the outputs operating at 50.
G.1.1 Battery Backup for the RCM5700/RCM5710 and RCM6700 Family The RCM5700/RCM6700 does not have a battery, but there is provision for a customer-supplied battery to keep the internal Rabbit 5000/6000 real-time clock running on the RCM5700/RCM5710 and RCM6700 family of modules. Battery Backup is not available on the RCM5750/5760 modules. The edge connector, shown in Figure G-1, allows access to the external battery. This makes it possible to connect an external 3 V power supply.
The actual life in your application will depend on the current drawn by components not on the RCM5700/RCM6700 and on the storage capacity of the battery. The RCM5700/RCM6700 does not drain the battery while it is powered up normally. Cycle the main power off/on on the MiniCore after you install a backup battery for the first time, and whenever you replace the battery.
