The MTFC8GAKAJCN-1M-WT is an 8GB eMMC 5.1 embedded flash storage device from Micron in a 153-ball BGA package (11.5x13mm). eMMC integrates a NAND Flash memory array (MLC or TLC) with a Flash controller in a single package, presenting a simple eMMC interface to the host. The controller handles all NAND management: wear leveling (distributing writes across all blocks), bad block management (remapping failed blocks), error correction (BCH or LDPC ECC with up to 40-bit correction per 1KB), and garbage collection (reclaiming space from invalidated pages). The eMMC 5.1 specification supports HS400 mode: 200MHz DDR clock on the CMD and DAT buses, achieving 400MB/s theoretical bandwidth (320MB/s typical). The 1.2V VDD2 supply powers the NAND core, while 1.8V VDDQ powers the I/O. The HS400 mode uses the DS (Data Strobe) signal from the eMMC to the host for read data timing, eliminating setup/hold timing margin issues. The device supports: (1) Command queuing (CQ) for improved random read/write performance by reordering commands; (2) Background operation (BKOPS) for automatic garbage collection during idle; (3) Secure erase and trim for efficient space management; (4) Write reliability features including power-fail protection and refresh of critical data. The -1M suffix specifies industrial temperature (-40C to +85C). The -WT suffix specifies tape-and-reel packaging. eMMC is the dominant non-removable storage solution for IoT, automotive infotainment, and embedded Linux systems.
