- Simplified System Design and Low System Cost
Integrated serial resistors eliminate the need for external resistors to preserve signal integrity, resulting in reduced BOM cost, real estate savings, and simplified system design.
- Parallel Capture Mode
The SAM3S is the first ARM® MCU with parallel data capture mode on PIOs and DMA support. The parallel data capture mode on the PIOs complements the external bus interface for data collection from external devices that are not compliant with standard memory read protocols, such as low-cost image sensors.
- Atmel QTouch Capacitive Touch Support
The SAM3S series is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders, and wheels in your application.
- Safety and Security
Memory protection unit improves code protection and secures multi-application/task execution. Unique 128-bit ID and scrambled external bus interface ensure software confidentiality while the hardware CRC checks memory integrity.
