Uncompromised Performance and Ease of Use
The Atmel® entry point into ARM® Cortex™ M3 technology, the SAM3N intelligently combines high-performance architecture, peripherals and power–saving techniques to deliver uncompromised performance. Available in multiple memory densities, pin counts and package types, the SAM3N offers a scalable solution to meet application requirements. It is supported by a full set of software libraries, project examples, tools and a worldwide ecosystem to shorten development cycle time. Pin-to-pin compatible with the SAM7S and the SAM3S, the SAM3N facilitates migration within the family.
Atmel QTouch Capacitive Touch Support — The SAM3N series is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders and wheels in your application.
Data Speedway — Native 3-layer bus AHB matrix support with 10 peripheral DMA channels and distributed memory for high-speed uninterrupted data flows with minimum processor overhead.
Simplified PCB 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 PCB design.
1.62 to 3.6V Operation and Low Power — True 1.8V±10% operation extends device operation when running from two AA alkaline batteries. The SAM3N only consumes 22 mA at 48 MHz operation and 1.9 uA in backup mode with the RTC running.
