SAMA5D21 Datasheet | Atmel

SAMA5D2 Series Atmel | SMART ARM-based Embedded MPU Introduction The Atmel® | SMART SAMA5D2 series is a high-performance, ultra-low-power ARM® Cortex®-A5 processor-based MPU running up to 500 MHz, with support for multiple memories such as DDR2, DDR3, DDR3L, LPDDR1, LPDDR2, LPDDR3, and QSPI Flash. The devices integrate powerful peripherals for connectivity and user interface applications, and offer advanced security functions (ARM Trust Zone®, tamper detection, secure data storage, etc.), as well as highperformance crypto-processors AES, SHA and TRNG. The SAMA5D2 series is delivered with a free Atmel Linux distribution and bare metal C examples.
