STR91xFA is a series of ARM-powered microcontrollers which combines a 16/32-bit ARM966E-S RISC processor core, dual-bank flash memory, large SRAM for data or code, and a rich peripheral set such as Ethernet, USB, CAN, AC motor control, 4 timers, ADC, RTC and DMA.

The ARM966E-S core can perform single-cycle DSP instructions, good for speech processing, audio algorithms, and low-end imaging.

This makes STR91xFA 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.
