Atmel SAM4S devices operate at 120MHz and integrate Atmel’s Flash read accelerator and optional cache memory to increase system performance. Atmel SAM4S MCUs also offer a rich peripheral set for connectivity, system control, and analog interfacing. The SAM4S series achieves 200µA/MHz in dynamic mode at a low operating frequency and 1µA at 1.8V in back-up mode with the real-time clock (RTC) running. The devices are pin-to-pin and software compatible with SAM3 and SAM3N Cortex-M3 processor-based MCUs, offering a smooth upwards migration path for performance and memory size.
