SAMA5D2 Series


The SAMA5D2 series is a high-performance, ultra-low-power ARM Cortex-A5 processor based MPU. The Cortex A5 processor 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 latest-generation technologies such as DDR3, LPDDR3, and QSPI Flash. It integrates powerful peripherals for connectivity (EMAC, USB, dual CAN, up to 10 UARTs, etc.) and user interface applications (TFT LCD controller, PCAP and resistive touch controllers, touch controller, class D amplifier, audio PLL, CMOS sensor interface, etc.). The devices offer advanced security functions to protect customer code and secure external data transfers. These include ARM TrustZone, tamper detection, secure data storage, hardware encryption engine, on-the-fly decryption of code stored in external DDR or QSPI memory and a secure boot loader. The devices comes with a free Microchip Linux distribution.
