Atmel SAM3S

Converging Performance and Simplicity

The Atmel® | SMART™ SAM4N series comprises the entry point into our portfolio of Flash microcontrollers based on the ARM® Cortex®-M4 core. These microcontrollers feature a 100MHz operating frequency and offer up to 1MB of Flash, multiple serial communication peripherals and analog capability. This combination of features—plus low power consumption—makes the Atmel SAM4N series ideal for a wide range of applications in industrial automation, consumer and appliance, and energy metering markets.
The Atmel SAM4N series offers pin-to-pin compatibility with Atmel SAM4S, SAM3S, SAM3N and SAM7S devices, facilitating easy migration within the portfolio.
