SAM4S Microcontrollers by Atmel

Semiconductor Vendor with ARM Processor RTL license from ARM

Product 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
• 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.

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 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.

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 design cycle with a comprehensive integrated development tool, evaluation kit and software package. For rapid evaluation and code development, Atmel and industry-leading third parties provide a full range of development tools, RTOS, middleware and support services to reduce time to market.
