ATSAMA5D22A-CUR [Microchip]

The SAMA5D2 Series is a high-performance, power-efficient embedded MPU based on the Arm Cortex-A5 processor. It integrates the Arm NEON SIMD engine for accelerated multimedia and signal processing, a configurable 128-Kbyte L2 cache and a floating point unit (FPU) for high-precision computing. The device features an advanced user interface and connectivity peripherals. Advanced security is provided by powerful cryptographic accelerators, by the Arm TrustZone technology securing access to memories and sensitive peripherals, and by several hardware features that safeguard memory content, authenticate software, detect physical attacks and prevent information leakage during code execution. The device supports DDR2, DDR3, DDR3L, LPDDR1, LPDDR2, LPDDR3, QSPI and e.MMC Flash, and SLC/MLC parallel NAND Flash memory up to 32-bit ECC. The comprehensive peripheral set includes an LCD TFT controller with overlays for hardware-accelerated image composition, an image sensor controller, audio support through I2S, SSC, a stereo Class D amplifier and a digital microphone. Connectivity peripherals include a 10/100 EMAC, USBs, CANs, FLEXCOMs, UARTs, SPIs and two QSPIs, SDIO/SD/e.MMCs, and TWIs/I2C. Protection of code and data is provided by automatic scrambling of memories and an Integrity Check Monitor (ICM) to detect any modification of the memory contents. The SAMA5D2 also supports execution of encrypted code (QSPI or one portion of the DDR) with an 'on-the-fly' encryption-decryption process. With its secure design architecture, cryptographic acceleration engines, and secure bootloader, the SAMA5D2 is the ideal solution for point-of-sale (POS), IoT and industrial applications requiring device authentication, anti-cloning, data protection and secure communication.
