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 1MB of Flash and 128KB 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 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.
