Device Overview

Summary

The SAMA5D21 is a high-performance, 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 device integrates powerful peripherals for connectivity and user interface applications, and offers advanced security functions (Arm TrustZone® , tamper detection, secure data storage, secure boot, etc.), as well as high-performance crypto accelerators AES, SHA and TRNG.

The SAMA5D2 series is delivered with free Linux® distributions, MPLAB X IDE, MPLAB Harmony v3 and bare metal C examples.

Microchip provides fully tested and validated power management solutions complying with the SAMA5D21 specific power sequencing needs for various supply and DRAM configurations-enabling a risk-free solution immediately on first power-up. Go to the Treelinktool -> DC/DC converters and select SAMA5D2 to find more details.
