Atmel's Cortex™-M3 MCU brings more connectivity to the SAM3 family

Image of Atmel's SAM3A Flash MCUThe Atmel® 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). Devices are available in a dual-bank configuration of 256 KB and 512 KB Flash total and in 100-pin QFP and BGA package options. The architecture is designed to support high-speed data transfers and includes a multi-layer bus matrix plus dual SRAM banks, direct memory access (DMA) channels and peripheral DMA controller (PDC) for applications supporting multi-task operations. The SAM3A series is ideal for networking applications in the industrial embedded market and in home and building automation, smart grids and industrial automation.
