SAMA5D4 SERIES Low-Power Arm® Cortex®-A5 Processor-Based MPU, 600 MHz, Video Decoder, Graphic LCD, Camera Interface, Dual 10/100 Ethernet with IEEE®1588, Advanced Security Description The SAMA5D4 Series is a high-performance, power-efficient Arm® Cortex®-A5 processor-based MPU running at up to 600 MHz. It integrates the Arm NEON™ SIMD engine for accelerated signal processing, multimedia and graphics, as well as a 128 KB L2-Cache for high system performance. The device Features the Arm Trust Zone® enabling a strong security perimeter for critical software, as well as several hardware security Features . The device also Features advanced user interface and connectivity peripherals. The SAMA5D4 devices have three software-selectable low-power modes: Idle, Ultra-low-power, and Backup. In Idle mode, the processor is stopped while all other functions can be kept running at normal operating bus frequency. In Ultralow-power mode, the processor is stopped while all other functions can be kept running at minimum operating bus frequency. In Backup mode, only the real-time clock, real-time timer, backup SRAM, backup registers, and wakeup logic are running. The SAMA5D4 Features an internal multi-layer bus architecture associated with 32 DMA channels to sustain the high bandwidth required by the processor and the high-speed peripherals. The device supports DDR2/LPDDR/LPDDR2 and SLC/MLC NAND Flash memory with 24-bit ECC. The prehensive peripheral set includes a 720p hardware video decoder, an LCD controller with overlays for hardware-accelerated image position, a resistive touchscreen function, and a CMOS sensor interface. Connectivity peripherals include a dual 10/100 Ethernet MAC with IEEE1588, three HS USB ports, UARTs, SPIs and I2Cs. Security Features include an “on-the-fly” encryption-decryption process from the external DDR memory, tamper detection pins, secure storage of critical data, an integrity check monitor (ICM) to detect modification of the memory contents and...
