Atmel Cortex-M Family

The Atmel SAM4S16, the first member of our SAM4 family, operates at a maximum speed of 120MHz and features 1MB of Flash, 128KB of SRAM and a full peripheral set. Energy-efficient, the SAM4S16 achieves 200uA/MHz in dynamic mode at low operating frequency and below 25uA in wait mode (RAM retention). Software and pin compatibility ensure seamless migration between the SAM4S16 and members of the Atmel SAM7S, SAM3S and SAM3N series. Get details on the SAM4S16.
