Chapter 2. Purpose This RDK is an evaluation and demonstration tool for Renesas RX62N microcontrollers. The goal is to provide the user with a powerful debug and demonstration platform targeted at common applications. A set of human/machine interfaces are tightly integrated with the features of the RX62N and the software demonstration programs providing the user with an accessible platform to rapidly evaluate and customize.

Chapter 3.Power Supply 3.1. Requirements This RDK gets its power from the Segger J-Link Lite USB connection or optionally from a regulated 5V power supply. The optional power jack is a center positive connector using a 2.1 mm barrel. Warning The RDK is neither under nor over-voltage protected. Use a 5v !REGULATED! center positive supply which can source at least 1 Amp. 3.2.
Chapter 4. Board Layout 4.1. Component Layout The following diagram shows the top layer component layout.
4.2. Board Dimensions The following diagram gives the board dimensions and connector positions. All through hole connectors are on a common 0.1” grid for easy interfacing.
Chapter 5. Block Diagram Figure 5-1 shows the CPU board components and their connectivity.
Figure 5-2 shows host PC connection to the RDK board.
Chapter 6. User Circuitry 6.1. Switches There are five switches located on the CPU board. The function of each switch and its connection are shown in Table 6-1. Switch Function Microcontroller SW1 Connects to an IRQ line for user controls. IRQ8, Pin 95 SW2 Connects to an IRQ line for user controls. IRQ9, Pin 93 SW3 Connects to an IRQ line for user controls. IRQ10, Pin 92 SW4 (RESET) When pressed, the RDK microcontroller and JLink circuit are reset.
6.2.Debug LCD Module A debug LCD module is supplied on the RDK. The debug LCD module uses an SPI interface to reduce the pin allocation. Software contrast control is also provided. The module supplied with the RDK uses 3.3v. The display is a 96 x 64 graphics display and uses a white LED backlight. Note there is a footprint, LCD1, for a 2 x 8 character display. This display is not populated – but can be used in a standard 4 bit nibble configuration if desired.
Table 6-3, below, shows the user LED pin references and their corresponding microcontroller port pin connections.
6.6. Audio (Audio Out, Mic, Speaker, Volume Potentiometer) An amplified stereo audio output jack is provided and connected to the timer circuit. TIOCA8A is used for Right audio channel and comes out on CPU pin 64. TIOC8B is used for the Left audio channel and comes out on CPU pin 63. The stereo amp is powered by a National Semi LM4808. An on-board Analog Devices Inc. (ADI) Silicon microphone (ADMP401) is connected to the ADC channel AN5 (CPU pin 89) using an ADI SSM2167 low voltage Microphone preamplifier.
6.9. USB The USB module can be configured as Host, Device or OTG with the correct switch settings on SW6. Function / Device / Slave mode: This mode does not take any external power circuitry to implement. Simply put the SW6 DIP switches to the proper setting as in table 6-7 and configure the software appropriately. Host mode: Connect the included MiniAB to Host adapter Cable to have the proper cable connection for USB Host. This mode uses U12 and associated passive circuitry to create USB Power.
USB DIP Switch Settings (SW6) Mode No. SW6.1 SW6.2 SW6.3 SW6.4 USB Host OFF OFF ON OFF USB Function / device/ slave ON OFF OFF ON USB On the Go (OTG) OFF ON OFF OFF Table 6-7: USB DIP Switch SW6 settings 6.10. Ethernet The Ethernet module conforms to the Ethernet or IEEE802.3 media access control (MAC) standard. Ethernet controller is connected to the direct memory access controller for Ethernet controller (E-DMAC) and carries out high-speed data transfer to and from the memory.
The National Semiconductor 10/100 DP83640 Precision PHYTER® Ethernet PHY supports the IEEE1588 Precision Time Protocol (PTP) providing precision clock synchronization for real-time industrial connectivity. The RDK includes a GPIO/Interrupt connection between the PHY and the RX62N for PTP event processing, and a direct LED connection for timing indications. The DP83640 captures a time stamp at the physical layer level with an accuracy of <10ns.
Table 6-10 below describes the function of the jumper headers.
6.14. Oscillator Sources All crystals are provided by Epson Electronics America. A crystal is fitted on the RDK and used to supply the main clock to the Renesas microcontroller. Table 6-11 details the crystals that are fitted on the RX62N RDK. Component Function Frequency Crystal (X1) CPU/USB Clock 12 MHz Crystal (X2) CPU/RTC Clock 32.768 MHz Crystal (X3) Ethernet Clock 25 MHz Crystal (X4) J-Link Lite System 18.432 MHz Table 611: Oscillators / Resonators 6.15.
Chapter 7. Modes This RDK supports the 3 CPU modes: Single Chip Mode, Boot Mode and USB Boot Mode. These modes are selected by SW5 MD0 and MD1 pins. Placing the switch in the ‘On’ position sets the value to a logic ‘0’, and the ‘Off’ position sets the value to a logic ‘1’. The base configurations should only be set when the RDK is powered off. Mode No.
Chapter 8. Programming Methods The RDK is intended for use with HEW and includes an integrated Segger J-Link Lite debugger. Refer to RX62N Group Hardware Manual for details of programming the microcontroller without using these tools. The on-board J-Link Lite is pre-programmed at the factory and configured for normal operation. The debugger can be disabled by fitting a jumper to the J-Link disable 2-pin header. This is useful if the board needs to be put into either USB or UART boot mode.
Chapter 9. Headers 9.1. Extension Headers Table 9-1 shows the controller pin headers and their corresponding microcontroller connections. The header pins connect directly to the microcontroller pin.
