Embest STDV711F Evaluation Board
The STDV711F evaluation board is intended as a low-cost development platform to enable rapid evaluation of the STR71x series of 32-bit 64-pin ARM7 core microcontrollers from STMicroelectronics. The board is based on STR711FR2T6 microcontroller with on-chip 256+16Kbyte high-speed single voltage flash memory and 64Kbyte high-speed RAM. It is a highly integrated microcontroller with an embedded ARM7TDMI core and is compatible with all ARM tools and software. Serial peripheral interfaces include 2 SPIs, 2 IIC interfaces, 4 UARTs, and HDLC, SC, MMC interfaces. The device provides a USB interface and a 4-channel 12-bit A/D converter, 4 16-bit standard timers, RTC (Realtime Clock), WDG (Watchdog) and enhanced I/O ports and supports JTAG with debug mode trigger request.
The STDV711F evaluation board takes advantage of STR711FR2T6 and has several boot mode selections. It integrates on board 2 RS232 UARTs, LEDs, test buttons, an ADC input and speaker to create a stand-alone versatile test platform. A 20-pin JTAG interface is also provided on this board to support high-speed download, in-circuit debugging and flash programming. It integrates a high-speed USB2.0 interface and 30 I/Os of the CPU are fully expanded on the board to support HDLC, SC interfaces and etc.
The board comes with documentation, schematics and plenty of example programs in source code to support the hardware platform. This is an idea platform for applications such as biometric chip card readers, point-of-sale and vending machines, testing equipment, USB memory sticks, PC keyboards and fingerprint transponders.
