Description
Based on the powerful ARM® Cortex™-M4 processor, the Atmel® SAM4S series extends the Atmel Cortex-M portfolio to offer:
- Increased performance and power efficiency
- Higher memory densities up to 1MB of Flash and 128KB of SRAM
- And a rich peripheral set for connectivity, system control and analog interfacing.
SAM4S devices are pin-to-pin and software compatible with current SAM3 Cortex-M3-based MCUs, offering a smooth upwards migration path for performance and memory size.
The SAM4S series operates at 120MHz and integrates Atmel's Flash read accelerator and optional cache memory to increase system performance.
The SAM4S series achieves 200µA/MHz in dynamic mode at a low operating frequency; 30mA at 120MHz; and 3µA at 1.8V in back-up mode with the real-time clock (RTC) running.
Offering some of the best power consumption/performance rates on the market for standby mode, the SAM4S16 reaches 120MHz+ operating frequency with a RAM retention mode below 25µA.
The SAM4S series is touch-ready, offering native support for Atmel's market-leading QTouch® technology so you can easily implement buttons, sliders and wheels in your application.
