Introduction
The STR730-EVAL board is a complete development platform for the STR73x series.
It is a cost effective, flexible and open design to demonstrate the capability of the STR730
series of flash micro-controllers and to enable rapid evaluation of the STR73x devices and
available peripherals.
It includes the high performance STR730F ARM7TDMITM processor running at up to
36 MHz, that features a rich set of peripherals and serial communication interfaces,
including CAN (controller area network), STR730F, SPI EEPROM, I2C EEPROM and an
LCD display.
The board can be used as a versatile stand-alone test platform, supporting a CAN interface
and a UART RS232 interface, LED displays, 2 x 16 LCDs, piezo buzzer, test buttons, a JTAG
connector and an analog channel.
A wide choice of third party development tools are readily available in addition to the those
available from STMicroelectronics.
