Description

The SAMA5 series are high-performance, ultra-low power ARM Cortex-A5 core based MPU devices. They support multiple memories, including DDR3, LPDDR3, and QSPI Flash. A rich set of peripherals, user interfaces, and robust security features simplify the design for control panels/HMI, secure IoT gateways, connectivity, barcode scanners, printers and POS terminal applications. The low-power features and small packages are ideal for wearables and other battery-operated consumer devices. A wide range of third-party offerings complements our development kits and software support.
