Product Description

The SAMA5D2 series is a high-performance, ultra-low-power ARM Cortex-A5 processor-based MPU.  The Cortex-A5 runs up to 500MHz and features the ARM NEON SIMD engine, a 128KB L2 cache and a floating-point unit.  It supports multiple memories, including DDR3, LPDDR3 and QSPI Flash.  It integrates powerful peripherals for connectivity:  EMAC, up to 3 HS USB ports, up to 2 CAN ports, up to 2 SDIO/SD/MMC, up to 10 UARTs; and for user interface applications:  TFT LCD controller, touch controllers, class D amplifier, audio PLL, 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 RSA, ECC, 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 or QSPI memory and a secure boot loader.  These devices come with a free main-lined Linux distribution.

Features
      • Low System Cost and High Value Integration:

      - DDR3/DDR3L/LPDDR3 support

      - Embedded audio subsystem

      - 0.8mm ball pitch package reduces PCB design complexity

      - Simple power management scheme

      - 4-layer PCB

      • Ultra-Low Power Consumption:

      - Ultra-low-power architecture for extensive battery life

      - <200uA retention mode with fast wake-up

      - 5uA in backup mode

      - New backup mode with DDR self-refresh

      • State-of-the-Art Security:

      - Hardware encryption engine

      - Tamper pins and secure key storage

      - Active die shield and environmental monitors (D23 & D28 only)

      - Secure boot

      • Extensive Ecosystem:

      - Free Linux® and Qt SDK

      - Complete set of C examples for non-OS users

      - Low-Cost Development board

      - Multiple third-party software and hardware partners
