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 STR730-EVAL board is based on the STR730FZ2T7, a highly integrated
microcontroller, running at up to 36 MHz that uses the popular ARM7TDMI
CPU featuring on-chip high speed single voltage flash memory and high-speed RAM, clock
generation via PLL, and numerous on-chip peripherals.
This board is intended as low cost development platform to demonstrate the capability of the
STR730 series of flash micro-controllers and to enable rapid evaluation of the STR730
devices and available peripherals.
The STR730-EVAL board has 8-Kbit SPI EEPROM and 8-Kbit I
CAN and RS232 interfaces. It includes a 2 x 16 programmable LCD display supported by
select, next, back, previous and wake-up push buttons.
The hardware platform of the STR730F 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 real-time OS and middleware.
Design schematics can also be supplied in electronic format to those customers with
compatible design environments.
