Mouser Electronics, Inc. stocks the expanded SAM3 Cortex™-M3 MCUs from Atmel. These include the SAM3N (entry level), SAM3S (simplify system design/reduce power consumption) and SAM3A (connectivity/PHY).
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. The Atmel® SAM3S Cortex™ M3 Flash MCU integrates features to simplify system design and reduce power consumption down to 2.3 mW at 1 MHz, 1.45mW/MHz at 64 MHz operation and 1.6 uA in backup mode with the RTC running. The SAM3S is the ideal migration path to a more powerful and feature-rich MCU. SAM3A ARM® Cortex™-M3 Flash-based microcontroller (MCU) features connectivity peripherals including a dual CAN interface and high-speed USB (HS USB) MiniHost and device with on-chip physical layer (PHY).
