The STR710-EVAL board is a complete
development platform for the ST R71x series. The
STR710-EVAL board is a cost effec tive , fle xible and
open design to demonstrate the capability of the
STR71x series of flash micro-controllers and to
enable ra pid e valuation of the STR71x de v ices and
available peripherals. It includes the high
performance STR710FZ2T6 ARM7TDMI
that boasts 256 Kbytes embed ded flash with “bestin-class” random access time, 64 Kbytes on-chip
high speed SRAM as well as up to 10 serial
communication int erfaces, including USB and CAN.
The STR710-EVAL board include s SRAM and f lash
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 to create a versatile stand-alone
test platform. A wide choice of third party
development to ol s u pp o rt is re ad i l y available, in
addition to thos e av a ilabl e from ST Microelectr onics .

STR710-EVAL board 1 Introduction
1 Introduction
STMicroelectronics is a global independent semiconductor company that designs, develops,
manufac tures a nd mark e ts a broad r ange of semi condu ctor int egr at ed circ uits an d di screte devices
used in a wide variety of applications.
The STR710-EVAL board is based on the STR710FZ2T6, a highly integrated micro controller,
running at 48 MHz that combines the popular ARM7TDMI
TM
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 demons trate the capability of the
STR71x series of flash micr o-con troller s and t o ena bl e ra pid e valuation of the STR71x devic es 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 s upports USB, CAN and RS232 inte rfaces. The on-board chip
STR710FZ2T6 is an ARM7TDMI
TM
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 super set 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 pl atform of the STR710F series is supported by an extensive software support
package, including de vice drivers in ANS I C source form and demonstration softw are. It is flashe d
with a demonstr ation appli catio n that sho ws the b asic f e atures o f the de vic e. De v el opment too ls are
readily available. This is complimented by a range of third party real-t ime OS and middleware.
Design schematics can also be supplied in elect r onic format to those customers with compatible
design env i r on m e nts.
