Atmel SAM4S Series

Scalable Performance and

Memory Density, Power Efficiency

•

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

•

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.
