The SAMA5D4-XULT board is based on the integration of an ARM Cortex®-A5-based microprocessor with external memory, one Ethernet physical layer transceiver, two SD/MMC interfaces, two host USB ports and one device USB port, one 24-bit RGB LCD and HDMI interface and debug interfaces. Seven headers, compatible with Arduino R3 (Uno, Due) and two Xplained headers are available for various shield


The SAMA5D4 series is a high-performance, power-efficient ARM Cortex-A5 processor MPU capable of running up to 528 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 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 touch screen 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.
