MYIR has launched the MYC-YT113i CPU Module, offering larger capacities of external DDR3 memory options (512MB/1GB) to meet more customers’ needs while the MYC-YT113X CPU Module is fixed at 128MB on-chip DDR3 memory.

Measuring 39 by 37mm, the MYC-YT113i CPU is based on Allwinner’s T113-i dual-core ARM Cortex-A7 processor and integrates 4GB or 8GB eMMC. Extended IO signals are carried out through 140-pin stamp-hole interface and 50-pin LGA pads. It is ready to run Linux and suitable for applications such as HMI, industrial automation, display, and control terminals.

The MYD-YT113i Development Board is built around the MYC-YT113i CPU Module and provides a complete development platform for prototyping and evaluating purpose. Its base board has explored a rich set of

peripherals and interfaces including serial ports, one Gigabit Ethernet, two USB 2.0 HOST and one USB 2.0 OTG, one Micro SD card slot, one M.2 Socket for USB based 4G/5G LTE Module with two SIM card holders, one USB2.0 based Wi-Fi module, one GPIO/I2C/UART/SPI/CAN extension header, Audio input/output and LVDS display interface. MYIR also offers MY-WIREDCOM RPI Module(RS232/RS485/CAN) and MY-LVDS070C LCD Moduleas options for the MYD-YT113i Development Board to enhance the functionality of the board.

The MYC-YT113i CPU Module is provided with three standard configurations:

  • MYC-YT113i-4E512D-110-I (with 512MB DDR3 and 4GB eMMC)
  • MYC-YT113i-8E512D-110-I (with 512MB DDR3 and 8GB eMMC)
  • MYC-YT113i-8E1D-110-I (with 1GB DDR3 and 8GB eMMC)

The RAM/Flash can also be customised and discount is to be offered for volume quantities which can start from only $12.80.

MYIR also provides OEM/ODM services to help customers accelerate their time to market and save cost.
