STMicroelectronics brings the power of an ARM966E-S processor core to the world of general purpose Flash
microcontrollers, opening endless opportunities to embedded system designers by making networking and other
demanding applications easy and affordable.
The STR91x family of MCUs delivers up to 96 MIPS peak performance while executing code directly from its Flash
memory, executes single-cycle DSP instructions within its ARM966E-S core, and includes Ethernet, USB, and CAN
interfaces. These features, combined with Flash memory sizes reaching 2.1 Mbytes and a vast 96 Kbytes SRAM,
make the
