The SAMA5D3 series high-performance power-efficient Embedded MPU based on the ARM® Cortex®-A5 processor, achieving 536MHz with power consumption levels below 0.5mW in low-power mode. The device features a floating point unit for high-precision computing 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 comprehensive peripheral set includes an LCD controller with overlays for hardware-accelerated image composition, a touchscreen interface and a CMOS sensor interface. Connectivity peripherals include Gigabit EMAC with IEEE1588, 10/100Mbps EMAC, multiple CAN, UART SPI and I²C.
