Atmel SAM4S Series
Scalable Performance and
Memory Density, Power Efficiency
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 2MB of Flash and 160KB of SRAM
•ꢀ And a rich peripheral set for connectivity, system control and analog interfacing.
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.
Key Features
•ꢀ Improved Performance Level — Built around the ARM Cortex-M4 processor, the SAM4S operates at 120MHz and
integrates Atmel’s 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.
•ꢀ Low Power Consumption — The SAM4S series achieves 200µA/MHz in dynamic mode at a low operating frequency;
30mA at 120MHz; and 1µA 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 SAM4S series reaches 120MHz operating
frequency with a RAM retention mode below 25µA.
•ꢀ Safety and Security — Integrated best-in-class hardware code protection:
•ꢀ Prevents access to on-chip memory to protect your intellectual property (IP).
•ꢀ 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.
•ꢀ Atmel QTouch Capacitive Touch Support — 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.
•ꢀ Ease of Use — Accelerate your development cycle with Atmel Studio 6, 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, Atmel 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.
