SAMA5D41 / SAMA5D42 SAMA5D43 / SAMA5D44 Atmel SMART ARM-based Embedded MPU DATASHEET Description The Atmel SMART SAMA5D4 Series is a high-performance, power-efficient ARM Cortex -A5 processor MPU capable of running 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 TrustZone 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 Ultra- low-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 comprehensive peripheral set includes a 720p hardware video decoder, an LCD controller with overlays for hardware-accelerated image composition, 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 includes 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 a secure boot. The product also includes a dedicated coprocessor for public key cryptography such as RSA and elliptic curves algorithms (ECC), as well as AES, 3DES, SHA function and TRNG. These features permit to protect the system against counterfeiting, to safeguard sensitive data, authenticate safe program or secure external data transfers. The SAMA5D4 series is optimized for control panel/HMI applications needing video playback and applications that require high levels of connectivity in the industrial and consumer market. Its security features make the SAMA5D4 well suited for secure gateways or for the IoT.
