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.
