Embest STDV710A Evaluation Board
Description
The STR710F-Z2T6 is an ARM-powered microcontroller with embedded Flash and RAM. It is based on the
ARM7TDMI core with low pin-count packages to aim at customers who want the power and flexibility of a
32-bit microcontroller plus an extensive range of peripheral functions and enhanced I/O capabilities. The
STR710F-Z2T6 with high connectivity is using various interfaces including CAN, USB, SPI, I2C, UART, EMI
(External Memory Interface) and etc. The controller is designed to target industrial control applications such as
factory automation, point-of-sale and vending machines, and testing equipment, as well as mass-market telecom
applications such as bridges and protocol translators.
Embest STDV710ATM Evaluation Board is intended as a low cost evaluation platform for STR710F-Z2T6
1
devices. The board expands all features of STR710F-Z2T6 microcontroller and support various additional
peripherals including 512k Bytes SRAM and 2M bytes flash on EMI. It integrates LEDs, buzzer, test buttons,
LCD, Ethernet, CAN, SPI, I2C, USB interfaces to create a versatile stand-alone test platform. Users can fully
take use of the board to meet your development requirements and applications. The Embest STDV710A
Evaluation Board Kit is a complete development environment contains an evaluation board, a JTAG debugger
interface and a plenty of sample programs for embedded development.

/TRST and /RESET
/TRST is the reset signal for the controller when debugging use the JTAG interface. /RESET is the reset signal
for CPU peripherals including on-chip and external. JP7 on board is used for the two reset signals. Considering
stability while debugging, JP7 is short-circuited on the back of the board and is of no use. If users don't want to
reset peripherals, you can chop up conjunctive wire on the back of the board. But you should note that JP7 be
short-circuited when running offline to assure reset controller while power-up reset.
IAP Enable
P1.8 of GPIO is used for enabling IAP program. If on-chip Flash is burned with IAP program which is provided
with the board, to short-circuit JP8 to active IAP function when resetting. (Boot mode should set from on-chip
4
flash booting.)
Note: The definition of this jumper is only valid when running IAP program. User program can use this
jumper for other purposes.
