SAMA5D2 Series Ultra-Low-Power Arm® Cortex®-A5 Core-Based MPU, 500 MHz, Graphics Interface, Ethernet 10/100, CAN, USB, PCI 5.0 Pre-Certified Introduction
The SAMA5D2 series is a high-performance, ultra-low-power Arm Cortex-A5 CPU-based embedded microprocessor (MPU) running up to 500 MHz, with support for multiple memories such as DDR2, DDR3L, LPDDR2, LPDDR3, and QSPI and e.MMC Flash. The devices integrate powerful peripherals for connectivity and user interface applications, and offer advanced security functions (Arm TrustZone®, tamper detection, secure data storage, etc.), as well as high- performance crypto accelerators AES, SHA and TRNG. Selected members of the SAMA5D2 series are qualified for extended industrial temperature range operation (-40°C to 105°C external temperature). The SAMA5D2 series is delivered with a free Linux® distribution and bare metal C examples.
