STR91xF is a series of ARM-powered microcontrollers which combines a 16/32-bit ARM966ES
RISC processor core, dual-bank Flash memory, large SRAM for data or code, and a rich
peripheral 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. The ARM966E-S core can perform single-cycle DSP instructions, good for speech processing, audio algorithms,
and low-end imaging.
This Preliminary Datasheet provides STR91xF ordering information, functional overview,
mechanical information, and electrical device characteristics.
