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.
