MYD-JA5D44 Development Board

The MYD-JA5D4X Development Boardis a complete evaluation platform for Atmel’s ARM Cortex-A5 based The MYD-JA5D4X Development Board is a complete evaluation platform for Atmel’s ARM Cortex-A5 based SAMA5D42 or SAMA5D44 processor which is among the SAMA5D4 MPU series and can operate at up to 600MHz. Compared to the previous Cortex-A5 SoC from Atmel, the SAMA5D3, the SAMA5D4 brings a L2 cache, NEON, a slightly different clock tree, a hardware video decoder, and Trustzone support. The MYD-JA5D4X board is built around MYIR’s MYC-JA5D4X CPU Module and has a specific designed base board which takes full features of SAMA5D4 SOC to extend a rich set of peripherals and interfaces including serial ports, two USB Host ports, one Mini USB Device port, two 10/100Mbps Ethernet ports, RS485, TF card slot, Audio in/out, HDMI, LCD and more.

MYD-JA5D4X Development Board

The MYC-JA5D42 and MYC-JA5D44 CPU modules are sharing the same circuit design with only minor CPU feature difference. The Atmel SAMA5D44 can support 720p resolution hardware video decoder while the SAMA5D42 cannot. The MYC-JA5D4X has integrated the SAMA5D4 processor, 512MB DDR2, 512MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY on board. They are served as the core controller of the MYD-JA5D4X development board and connected to the base board through DDR2 SO-DIMM 200-pin connector. They can also be embedded into your products directly which can speed up your time to market.

SAMA5D4 Series Devices

The MYD-JA5D4X Development Board comes along with Linux 3.18 software packages, necessary cable accessories as well as detailed documents to enable quick start when getting the goods out of box. It is an excellent EVM (Evaluation Module) and a good reference design for extensively evaluation, fast prototyping and creating applications that require video playback, audio, mass storage, networking, connectivity and more. Typical applications are such as control panel/HMI, fitness equipment, smart grid infrastructure, communications gateways, imaging terminals, etc.
