ATSAMA5D41B-CU Part Information

Details for ATSAMA5D41B-CU by Microchip Technology


Part Description

The SAMA5D4 series is a high-performance, ultra-low-power ARM Cortex-A5 processor-based MPU.  The Cortex-A5 runs up to 600MHz and features the ARM NEON SIMD engine, a 128KB L2 cache and a floating-point unit.  It supports multiple memories, including DDR2 and LPDDR2.  It integrates powerful peripherals for connectivity:  dual 10/100 EMACs, 3 HS USB ports, 2 SDIO/SD/MMC, 8 UARTs; and for user interface applications:  TFT LCD controller, touch controller, 720p hardware video decoder (H264, VP8, MPEG4), and a CMOS sensor (camera) interface.  These devices offer advanced security functions to protect customer code and secure external data transfers such as:  ARM TrustZone, tamper detection pins, a hardware encryption engine supporting AES, 3DES, as well as secure Hash Algorithm (SHA) and True Random Number Generator (TRNG), secure data storage for private keys, on-the-fly decryption of code stored in external DDR and a secure boot loader.  These devices come with a free main-lined Linux distribution.
