Description
The STR710-EVAL board is a complete development platform for the STR71x series. It is a cost effective, flexible and open design to demonstrate the capability of the STR71x series of flash microcontrollers and to enable rapid evaluation of the STR71x devices and peripherals. It includes the high performance STR710FZ2T6 ARM7TDMITM device with 256 Kbytes embedded flash with "best-in-class" random access time, 64 Kbytes on-chip high speed SRAM and up to 10 serial communication interfaces, including USB and CAN. The STR710-EVAL board includes SRAM and flash memory on the EMI to enable full freedom in development of large programs before custom hardware is designed. It integrates a 2 x 16 LCD, LEDs, UART, CAN, USB interfaces, piezo buzzer and test buttons in a versatile stand-alone test platform. A wide choice of third party development tool support is readily available, in addition to those available from STMicroelectronics.

1 Introduction

Introduction
STMicroelectronics is a global independent semiconductor company that designs, develops, manufactures and markets a broad range of semiconductor integrated circuits and discrete devices used in a wide variety of applications. The STR710-EVAL board is based on the STR710FZ2T6, a highly integrated microcontroller, running at 48 MHz that combines the popular ARM7TDMITM 32-bit RISC CPU with 256 Kbytes of embedded flash, 64 Kbytes of high speed SRAM, and numerous on-chip peripherals. This board is intended as low cost development platform to demonstrate the capability of the STR71x series of flash micro-controllers and to enable rapid evaluation of the STR71x devices and available peripherals. The STR710-EVAL board has 4 Mbytes of SRAM, and 4 Mbytes of flash on EMI, 1-Mbit SPI serial flash and 8-kbits EEPROM. It supports USB, CAN and RS232 interfaces. The on-board chip STR710FZ2T6 is an ARM7TDMITM 32-bit RISC micro-controller. This board includes a 2x16 programmable LCD display supported by reset, next and select push buttons. Because the STR710FZ2T6 is the superset of the STR71xF series, with 144-pin, EMI, 256 Kbytes of flash and 64 Kbytes of SRAM, an alternative use of the STR710-EVAL board is as an evaluation platform for STR711F and STR712F devices. The hardware platform of the STR710F series is supported by an extensive software support package, including device drivers in ANSI C source form and demonstration software. It is flashed with a demonstration application that shows the basic features of the device. Development tools are readily available. This is complimented by a range of third party realtime OS and middleware. Design schematics can also be supplied in electronic format to those customers with compatible design environments.

2.9
CAN interface
A general purpose, asynchronous serial I/O data port connected through a 9-pin D-type male connector with microswitch selectable low speed fault tolerant transceiver (L9669) or low or high speed selectable transceiver (L9615 or L9616). See Section 3.2: CAN bus connector on page 13.
Caution: The board schematic for the CAN interface detailed in Figure 16: CAN interface on page 20, is
not a reference design and should not be copied. To design a CAN interface with the STR710 please refer to the "STR71x Hardware Development Getting Started Guide AN1775".
2.10
RS232 serial interfaces
Two general purpose, asynchronous serial I/O data ports are connected through 9-pin D-type male connectors refer to Section 3.4: RS232 serial data connector on page 14. RS232-A connects directly to UART0, transmit and receive only. RS232-B connects to either UART1 or UART2 through switch 9, transmit and receive only. RTS is shorted to CTS and DTR is shorted to DSR at the connector for both interfaces.
2.11
External analog
An external analog input connector is provided, see Section 3.3: External analog on page 13 and Figure 11: STR710-EVAL board top level page 1 of 2 on page 15.
2.12
Analog input
The analog input to ADC is demonstrated by the variable resistor R63. Although there is a thermistor connected up to the analogue input AIN.1 in the schematics Figure 11: STR710EVAL board top level page 1 of 2 on page 15, it is not functional and has been removed from the product.
