Details for ATSAMA5D31A-CU by Microchip Technology

ATSAMA5D31

Part Description

The SAMA5D3 series is a high-performance, ultra-low-power ARM Cortex-A5 processor-based MPU.  The Cortex-A5 runs up to 536MHz and features a 128KB L2 cache and a floating-point unit.  It supports multiple memories, including DDR2 and LPDDR2.  It integrates powerful peripherals for connectivity:  Gigabit EMAC and/or 10/100 EMAC, 3 HS USB ports, up to 2 CAN ports, up to 3 SDIO/SD/MMC, up to 7 UARTs; and for user interface applications:  TFT LCD controller, touch controller, and a CMOS sensor (camera) interface.  These devices offer application security functions to protect against hacking such as a hardware encryption engine supporting AES, 3DES, as well as secure Hash Algorithm (SHA) and True Random Number Generator (TRNG) and a secure boot loader.  These devices come with a free main-lined Linux distribution.
