Key features

• Built around the ARM Cortex-M4 core, the SAM4S operates at 120 MHz and integrates the Flash read accelerator and optional cache memory to increase system performance.
• The SAM4S features a multi-layer bus matrix, multi-channel direct memory access (DMA) and distributed memory to support high data rate communication.
• The SAM4S series achieves 180 µA/MHz in dynamic mode and 1 μA at 1.8V in back-up mode with the Real-Time Clock (RTC) running.
• The SAM4S series reaches 120 MHz operating frequency with a RAM retention mode below 25 μA.
• Integrated best-in-class hardware code protection: Prevents access to on-chip memory to protect your intellectual property; Supports secure device reconditioning (chip erase) for reprogramming; A unique 128-bit ID and scrambled external bus interface ensure software confidentiality while the hardware CRC checks memory integrity.
• Microchip QTouch Capacitive Touch Support: The SAM4S series is touch-ready, offering native support for Microchip's market-leading QTouch technology so you can easily implement buttons, sliders and wheels in your application.
• Accelerate your development cycle with Atmel Studio, a seamless, easy-to-use Integrated Development Environment (IDE).
• Get a jump-start on your design with dedicated evaluation kits and software packages.
• For rapid evaluation and code development, Microchip and industry-leading third parties provide a full range of development tools, Real-Time Operating System (RTOS), middleware and support services to reduce time to market.
