Description
The STR720-EVAL board is a complete development platform for the STR720 series. It is a cost effective, flexible and open design to demonstrate the capability of the STR720 series of microcontrollers and enable rapid evaluation of the STR720 devices and peripherals. It uses the high performance STR720 ARM720TTM device that embeds 8 Kbytes unified cache, has a memory management unit (MMU), 16K program RAM and numerous peripheral interfaces, including USB and CAN. The STR720-EVAL board includes shared memory interface (SMI) SDRAM and flash memory on the external memory interface (EMI) to enable freedom in development of large programs before custom hardware is designed. It integrates a 2 x 16 LCD, LEDs, UART, CAN, USB interfaces and test buttons to create a versatile stand-alone test platform. A wide choice of third party development tools are available in addition to those available from STMicroelectronics.

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 STR720-EVAL board is based on the STR720, a highly integrated microcontroller, running at 66 MHz. It combines the popular ARM720TTM 32-bit RISC CPU that embeds 8 Kbytes of unified cache and a memory management unit (MMU) with16 Kbytes of program RAM, external SDRAM interface for up to 128 Mbytes of SDRAM, an EMI for up to 8 Mbytes of SRAM, flash or ROM and numerous on-chip peripherals. This board is intended as a low cost development platform to demonstrate the capability of the STR720 series of micro-controllers and to enable rapid evaluation of the STR720 devices and available peripherals. The STR720-EVAL board has 4 Mbytes of flash on EMI, 1-Mbit SPI serial flash and 16 Mbytes of SDRAM. It supports ATAPI, USB, CAN and RS232 interfaces. The on-board chip STR720RBQ6 is an ARM720TTM 32-bit RISC micro-controller with cache and MMU. This board includes a 2x16 programmable LCD display supported by reset, RTC reset, next, select and previous push buttons. The hardware platform of the STR720 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 complemented 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.

Overview
The STR720-EVAL board is a general purpose evaluation platform with ATAPI, USB, CAN (controller area network) and RS232 interfaces.
2.2
Processor
The board supports the STR720 ARM720TTM silicon - 208-pin PQFP version. This chip runs at a frequency of 66 MHz. Boot modes and configuration options are set using microswitches, see Section 2.15: Option switch settings on page 12
2.3
Debug
Software debug is performed using a standard 20-pin JTAG connection. This may connect to a JTAG in-circuit emulator.
2.4
Prototype area
A 2.54x2.54mm gridded area of 1mm holes is available for prototyping using wire wrap or similar prototyping techniques.
2.5
Reset
The reset sources are:

power on reset, push button reset, JTAG reset from an in-circuit emulator.

Power supplies
Power to the board is supplied using a lump in cord power supply providing 5 V to the board. All other required voltages are provided on-board by voltage regulators or voltage convertors.
2.8
USB full speed interface
USB full speed interface device supported by a type B connector. The USB clock uses a separate 48 MHz oscillator. See Section 3.1: USB on page 14.
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 (L9616). See Section 3.2: CAN bus connector on page 14. The L9669 transceiver only works in normal mode, the wake-up functionality is not implemented.
Caution: The board schematic for the CAN interface detailed in Section 4.10: STR720-EVAL board - CAN
interface, is not a reference design and should not be copied. To design a CAN interface with the STR720 please refer to the "STR720 Hardware Development Getting Started Guide AN1907".
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 3.3: RS232 serial data connector on page 15. RS232-A connects directly to UART1, transmit and receive only. RS232-B connects to UART2, transmit and receive only. RTS is shorted to CTS and DTR is shorted to DSR at the connector for both interfaces.
2.11
Analog input
The following analog inputs are provided, see the schematics Section 4.1 on page 18:

ADC connector: CN4, LM35 temperature sensor IC4 is connected to pin 4 of the ADC connector CN4 (pins 3 and 4 must be shorted to enable temperature sensing,) variable resistor VR1 is connected to pin 2 of the ADC connector CN4 (pins 1 and 2 must be shorted to enable the variable resistor.)
