Overview:


 

The CPU module (CM) board SAMA5D3-CM is the heart of the SAMA5D3x-EK. It connects to the main board through a SODIMM200interface and integrates the SAMA5D3 series processor and external memories. The CM board serves as a minimal CPU sub-system. All Three SAMA5D31, SAMA5D34, and SAMA5D36 processors share the same CM board circuitry with minor configuration settings.

The CM board connects to a carrier board containing its connectors, power supply and any expansion I/O through a standard gold-plated SODIMM 200-pin connection.

Hardware:


 

The SAMA5D3x devices are packaged in a BGA324-ball BGA package and share an identical footprint. As different interfaces can be defined using the same pins, the functions available on the evaluation board depend on the actual configuration of the CPU.

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 mW 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 touch screen 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.

Memory
Two SDRAM/DDR2 are used as main system memory. MT47H128M16 - 2 Gb - 16 Meg x 16 x 8 banks, the board provides up to 4 Gb of on-board, soldered DDR2 SDRAM. The memory bus is 32 bits wide and operates at up to 166 MHz.
