Jz144 Emmc [work] [TRUSTED]

The JZ144 (often specifically the JZ144GB) is a high-density, embedded Multi-Chip Package (eMCP) integrated circuit that combines eMMC flash memory and DDR3L DRAM into a single BGA144 package. It is primarily designed for compact industrial, mobile, and IoT applications where PCB real estate is limited. Key Specifications
