KLMBG2JETD-B041

Overview   The KLMBG2JETD-B041 is Samsung’s 32GB eMMC 5.1 embedded storage device, integrating the NAND array and an eMMC controller in a single 153-ball FBGA package (11.5 × 13 mm). The controller handles bad-block management, wear levelling and ECC, so the host side needs no NAND management layer of its own — the shortest development path when migrating away from raw NAND. HS400 mode is supported, giving up to 400 MB/s of bus bandwidth on the 8-bit data bus; against the 200 MB/s of HS200 the difference shows clearly in boot time and large sequential writes. Revision 5.1 adds Command Queuing and Cache Barrier over 5.0, improving random IOPS.     Specification
