C8051F500 DEVELOPMENT KIT USER’S GUIDE

1. Relevant Devices

The C8051F500 Development Kit is intended as a development platform for the microcontrollers in the

C8051F50x/51x MCU family.

The target board included in this kit is provided with a presoldered C8051F500 MCU (LQFP48 package)

and a C8051F502 (QFN32 package).

Code developed on the C8051F500 can be easily ported to the other members of this MCU family.

Refer to the C8051F50x/51x data sheet for the differences between the members of this MCU family.

2. Kit Contents

The C8051F500 Development Kit contains the following items:

C8051F500 Target Board

C8051Fxxx Development Kit Quick-Start Guide

AC to DC Power Adapter

USB Debug Adapter (USB to Debug Interface)

Two USB Cables

3. Hardware Setup Using a USB Debug Adapter

The target board is connected to a PC running the Silicon Laboratories IDE via the USB Debug Adapter as shown

in Figure 1.

1. Connect the USB Debug Adapter to one of the

DEBUG

connector on the target board (

DEBUG_A

DEBUG_B

) with the 10-pin ribbon cable. The recommended connection is to

DEBUG_A

as this microcon-

troller is the primary MCU on the board and more peripherals are easily available.

2. Connect one end of the USB cable to the USB connector on the USB Debug Adapter.

3. Connect the other end of the USB cable to a USB Port on the PC.

4. Connect the AC/DC power adapter to power jack P4 on the target board.

C8051F50x/51x 4.3. CP210x USB to UART VCP Driver Installation The Target Board includes a Silicon Labs CP210x USB-to-UART Bridge Controller. Device drivers for the CP210x need to be installed before the PC software can communicate with the MCU through the UART interface. 1. After opening Simplicity Studio for the first time, a dialog will prompt to install the CP210x drivers. Click Yes. The drivers can also be installed at any time by going to HelpInstall DriversCP210x VCP USB Drivers. 2.

Target Board The C8051F500 Development Kit includes a target board with a C8051F500 (Side A) and C8051F502 (Side B) device preinstalled for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the target board. Refer to Figure 4 for the locations of the various I/O connectors. Figure 5 on page 7 shows the factory default shorting block positions.

C8051F50x/51x 5.2. Target Board Power Options and Current Measurement The C8051F500 target board supports three power options: 1. 12 V dc power using the ac to dc power adapter (P4) 2. 5 V dc USB VBUS power from PC via the USB Debug Adapter (DEBUG_A) 3. 12 V dc power from the LIN external header (TB1) The two 12V power sources are ORed together using reverse-biased diodes (Z1 and Z2). The ORed power is regulated to a 5.0V DC voltage using a LDO regulator (U6).

C8051F50x/51x 5.4. Switches and LEDs Two push-button switches are provided on the target board for each MCU. Switch RESET_A is connected to the /RST pin of the C8051F500. Switch RESET_B is connected to the /RST pin of the C8051F502. Pressing RESET_A puts the C8051F500 device into its hardware-reset state, and similarly for RESET_B and the C8051F502 MCU. Switches P1.4_A and P1.4_B are connected to the MCU’s general purpose I/O (GPIO) pins through headers.
PAGE 10
C8051F50x/51x 5.6. Serial Interface (P5) A USB-to-UART bridge circuit (U5) and USB connector (P5) are provided on the target board to facilitate serial connections to UART0 of the C8051F500 (Side A). The Silicon Labs CP2102 USB-to-UART bridge provides data connectivity between the C8051F500 and the PC via a USB port. The TX and RX signals of UART0 may be connected to the CP2102 by installing shorting blocks on header J17.
PAGE 11
C8051F50x/51x 5.8. LIN Interface and Network (TB1) Both MCUs on the target board are connected to LIN transceivers through headers. These headers assume that the MCU’s crossbars are configured to put the LIN TX and RX pins on port pins P1.0 and P1.1 respectively. See the C8051F50x data sheet for crossbar configuration. The C8051F500 (Side A) is connected to the T1 transceiver through the J17 header and the C8051F502 (Side B) is connected to the T2 transceiver through the J26 header.

C8051F50x/51x 5.10. Voltage Reference (VREF) Connectors (J22 and J32) The VREF connectors can be used to connect the VREF pin from the MCU (P0.0) to external 0.1 uF and 4.7 uF decoupling capacitors. The C8051F500 (Side A) device is connected to the capacitors through the J22 header and the C8051F502 (Side B) device connects to its own set of capacitors through J32. 5.11. Expansion Connector (P1) The 96-pin expansion I/O connector P1 is used to connect daughter boards to the main target board.

C8051F50x/51x 5.12. Potentiometer (J20) The C8051F500 (Side A) device has the option to connect port pin P1.2 to 10K linear potentiometer. The potentimeter is connected through the J20 header. The potentiometer can be used for testing the analog-to-digital (ADC) converter of the MCU. 5.13. Power Supply I/O (Side A) (TB3) All of the C8051F500 target device’s supply pins are connected to the TB3 terminal block. Refer to Table 11 for the TB3 terminal block connections. Table 11.

C8051F50x/51x 5.15. Target Board Pin Assignment Summary Some GPIO pins of the C8051F500 MCU can have an alternate fixed function. For example, pin 46 on the C8051F500 MCU is designated P0.4, and can be used as a GPIO pin. Also, if the UART0 peripheral on the MCU is enabled using the crossbar registers, the TX signal is routed to this pin. This is shown in the “Alternate Fixed Function” column. The “Target Board Function” column shows that this pin is used as TX on the ‘F500 Target Board.
