Description
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 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 datasheet provides STR91xFA ordering information, functional overview, mechanical
information, and electrical device characteristics.
For complete information on STR91xFA memory, registers, and peripherals, please refer to the
STR91xFA Reference Manual.
For information on programming the STR91xFA Flash memory please refer to the STR9 Flash
Programming Reference Manual
For information on the ARM966E-S core, please refer to the ARM966E-S Rev. 2 Technical
Reference Manual.
