                                 Embest STDV912F Evaluation Board

Description
The STR912FW42 is among the STMicroelectronics STR91xF series ARM-powered
microcontrollers, which combines a 16/32-bit ARM966E-S RISC processor core with up to
96Kbytes SRAM, 256Kbytes Main Flash and 32Kbytes 2nd Flash. The ARM966E-S core can
perform single-cycle DSP instructions, good for speech processing, audio algorithms, and
low-end imaging. The microcontroller is also equipped with USB, CAN, Ethernet, AC motor
control, 4 timers, ADC, RTC, DMA and up to 80 GPIO. The rich peripherals set to form an ideal
embedded controller for a wide variety of applications such as point-of-sale terminals, industrial
automation, security and surveillance, vending machines, communication gateways, serial
protocol conversion, and medical equipment.


                                                                                                     1
Embest STDV912FTM Evaluation Board is an effective ARM9 platform for STMicroelectronics
STR912 microcontroller (MCU) family. The board takes all advantages of STR912FW42
microcontroller and integrates RS232, LEDs, audio, buzzer, test buttons, LCD, Ethernet, CAN2.0,
USB device, JTAG interface to create a versatile stand-alone test platform. All 128 pins of the
CPU can be extended to meet your development requirements and applications. A plenty of
sample programs are provided for this embedded development. Embest also provides
development tools for your options including IDE, flash programmer and emulators you may
need to help you get your product to market fast.
