MYIR MYC-J1028X CPU module features NXP LS1028A dual Cortex-A72 SoC with time-sensitive networking (TSN)

MYIR has introduced the MYC-J1028X CPU module based on NXP LS1028A dual Cortex-A72 processor with time-sensitive networking (TSN) support, as well as the MYD-J1028X development board with five Gigabit Ethernet ports, and other interfaces to evaluate the solution.

The MYC-J1028X is equipped with 2GB DDR4, 8GB eMMC flash, a 32Kbit EEPROM, and a temperature sensor by default, and exposes all I/Os through a 314-pin MXM 3.0 edge connector. The module also comes with footprints to solder a QSPI NAND Flash, XSPI NOR Flash, and/or ECC memory. Typical applications include industrial routers, industrial control, edge computing, automotive electronics, industrial IoT, and more.
