SAMA5D31 Datasheet | Atmel

ARM-based Embedded MPU SAMA5D3 Series Description The Atmel SAMA5D3 series is a high-performance, power-efficient embedded MPU based on the ARM ® Cortex ® -A5 processor, achieving 536 MHz with power consumption levels below 0.5 m W in low-power mode. The device Features a floating point unit for high-precision puting and accelerated data processing, and a high data bandwidth architecture. It integrates advanced user interface and connectivity peripherals and security Features . The SAMA5D3 series Features an internal multi-layer bus architecture associated with 39 DMA channels to sustain the high bandwidth required by the processor and the high-speed peripherals. The device offers support for DDR2/LPDDR/LPDDR2 and MLC NAND Flash memory with 24-bit ECC. The prehensive peripheral set includes an LCD controller with overlays for hardware-accelerated image position, a touchscreen interface and a CMOS sensor interface. Connectivity peripherals include Gigabit EMAC with IEEE1588, 10/100 EMAC, multiple CAN, UART, SPI and I2C. With its secure boot mechanism, hardware accelerated engines for encryption (AES, TDES) and hash function (SHA), the SAMA5D3 ensures anti-cloning, code protection and secure external data transfers. The SAMA5D3 series is optimized for control panel/HMI applications and applications that require high levels of connectivity in the industrial and consumer markets. Its lowpower consumption levels make the SAMA5D3 particularly suited for battery-powered devices. There are five SAMA5D3 devices in this series. Table 1-1 “SAMA5D3 Device Differences” shows the differences in the embedded Features . All other Features are available on all derivatives; this includes the three USB ports as well as the encryption engine and secure boot Features . 11121D- ATARM- 03-Apr-14 1.
