Description of product

MYC-SAMA5D44 CPU module | ATMEL SAMA5D44 ARM Cortex-A5 Controller Board-Welcome to MYIR

Measuring only 67.6mm by 45mm, the tiny MYC-JA5D4X series CPU Modules are highly-integrated Linux-ready SOM (System on Modules) cards ideal for your next embedded design. It is based on Atmel’s SAMA5D4 series ARM Cortex-A5 MPUs which can operate at 600MHz (945DMIPS). 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. Additionally, the MYC-JA5D4X module has 512MB DDR2 SDRAM, 512MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY on board and is equipped with one SO-DIMM 200-pin connector to bring out all the I/O signals from the CPU Module. It is ideal for any high-performance, low-power and cost-sensitive industrial application such as control panels/HMI, fitness equipment, smart grid infrastructure, communications gateways, imaging terminals and more.



The MYC-JA5D4X series CPU Modules allow two selections of Atmel SAMA5D42 and SAMA5D44 processors. The only difference between the two processors is that the SAMA5D44 supports Hardware video decoder while the SAMA5D42 cannot. MYIR provides comprehensive documents and ready-to-run software packages for running Linux 3.18 operating systems on the MYC-JA5D4X series modules.

MYIR offers a development board MYD-JA5D4X for evaluation and prototyping based on Atmel SAMA5D4 solutions. The board is using the MYC-JA5D4X as core controller to be mounted on the specific designed base board, delivering a rich set of peripherals and user interfaces including serial ports, USB Host/Device, Ethernet ports, RS485, TF card slot, Audio in/out, HDMI, LCD, Camera interface, etc.

MYD-JA5D4X Development Board

MYIR also provides custom design services, we can help with your base board design based on the MYC-JA5D4X CPU module rapidly; we can also modify on existing hardware, whether reducing, adding or removing functions according to your requirements.


The Atmel | SMART SAMA5D4 MPU is ideal for any high-performance, secure, and cost-sensitive industrial application. High-speed computing needs are supported by ARM Neon and a 128kB L2 cache that increases the overall system performance. The SAMA5D4 is an ideal fit for low-cost user interface applications that require video playback. The high-grade security features allow you to protect any system against counterfeiting and software theft, while also enabling you to securely store and transfer data.
