SAM3X ARM® Cortex®-M3 Flash-Based Microcontrollers

Microchip Technology SAM3X ARM® Cortex®-M3 Flash-Based Microcontrollers bring more connectivity by adding Ethernet, dual CAN, and high-speed USB (HS USB) MiniHost and device with an on-chip physical layer (PHY). These devices feature a dual-bank configuration of 256kb and 512kb Flash total and are available in 100-pin and 144-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 a peripheral DMA controller (PDC) for applications supporting multi-task operations. Microchip Technology SAM3X ARM® Cortex®-M3 Flash-Based Microcontrollers are ideal for networking applications in the embedded industrial market and home and building automation, smart grids, and industrial automation.
