SAM3A Microcontrollers with CAN Connectivity by Atmel

Semiconductor Vendor with ARM Processor RTL license from ARM

Product Description

The Atmel® SAM3A ARM® Cortex™-M3 processor-based Flash 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 256KB and 512KB 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.
