MTFC4GMWDQ-3M AIT

The MTFC4GMWDQ-3M AIT from Micron Technology is a 4GB eMMC 5.1 embedded NAND flash memory in a 153-ball VFBGA package. It integrates the NAND flash memory and controller in a single package, providing a complete managed storage solution. The eMMC 5.1 interface supports HS400 mode for up to 300MB/s read bandwidth. The integrated controller handles ECC, wear leveling, bad block management, and power-fail protection transparently. The AIT temperature grade supports -25C to +85C operation. Command queuing improves random I/O performance over legacy eMMC versions.

The MTFC4GMWDQ-3M AIT integrates a NAND flash memory array with an on-die controller. The controller manages all flash operations including ECC (error correction code), wear leveling across all blocks, bad block detection and replacement, and power-fail recovery. The eMMC interface uses an 8-bit parallel bus with CMD/CLK/DAT signals. In HS400 mode, data is clocked on both rising and falling edges (DDR) at 200MHz, achieving 400MB/s raw bandwidth. The controller maps logical block addresses (LBAs) to physical flash pages, hiding the complexity of NAND management from the host.
