描述 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 featuresthe ARM NEON SIMD engine, a 128KB L2 cache and a floating-point unit.? It supports multiple memories, including DDR2and LPDDR2. ?It integrates powerfulperipherals for connectivity:? dual 10/100EMACs, 3 HS USB ports, 2 SDIO/SD/MMC, 8 UARTs; and for user interfaceapplications:? TFT LCD controller, touchcontroller, 720p hardware video decoder (H264, VP8, MPEG4), and a CMOS sensor (camera)interface. ?These devices offer advancedsecurity functions to protect customer code and secure external data transferssuch as: ?ARM TrustZone, tamper detectionpins, a hardware encryption engine supporting AES, 3DES, as well assecure Hash Algorithm (SHA) and True Random Number Generator (TRNG), securedata storage for private keys, on-the-fly decryption of code stored in externalDDR and a secure boot loader. ?Thesedevices come with a free main-lined Linux distribution.
