Microchip Technology SAMA5D2 Series 32-Bit Microprocessors

Microchip Technology SAMA5D2 Series 32-Bit Microprocessors are high-performance, ultra-low-power MPUs based on the Arm® Cortex®-A5 Core. The Cortex A5 Processor runs up to 500MHz and features the Arm Neon™ SIMD technology engine, a 128KB L2 cache, and a Floating Point Unit (FPU). It supports multiple memories, including DDR3, LPDDR3, and QSPI Flash. These devices integrate powerful peripherals for connectivity, including EMAC, USB, dual CAN, up to 10 UARTs, and more. The SAMA5D2 MPUs also offer a broad range of integrated user interface applications, such as TFT LCD controllers, projected capacitive and resistive touch controllers, class D amplifiers, audio PLL, and CMOS sensor interfaces. 

The Microchip Technology SAMA5D2 MPUs 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.
