Microchip SAMA5D2 Series of Microprocessors (MPUs)

Arm® Cortex®-A5 based device runs up to 500 MHz

The SAMA5D2 series by Microchip is a high-performance, ultra-low-power Arm® Cortex®-A5 based microprocessor (MPU).

The Cortex A5 processor runs up to 500 MHz and features the Arm Neon™ SIMD technology engine, a 128 KB L2 cache and a floating point unit. It supports multiple memories, including latest-generation technologies such as DDR3, LPDDR3 and QSPI Flash.

The SAMA5D2 MPU integrates powerful peripherals for connectivity (EMAC, USB, dual CAN, up to 10 UARTs, and more) and user interface applications (TFT LCD controller, projected capacitive and resistive touch controllers, class D amplifier, audio PLL, CMOS sensor interface, etc.).

These microprocessors offer advanced security functions to protect customer code and secure external data transfers. They include Arm TrustZone® technology, tamper detection, secure data storage, hardware encryption engine, on-the-fly decryption of code stored in external DDR or QSPI memory and a secure bootloader.

They also come with a free Microchip Linux® distribution.
