KLM8G1GEUF-B04Q057 – eMMC 5.1 – Samsung

Samsung KLM8G1GEUF-B04Q057 is an 8GB automotive-grade eMMC 5.1 managed NAND device (64Gb MLC) in a 153-ball FBGA package, rated for -40°C to +105°C operation with HS400 (200 MHz DDR) interface support.

The Samsung KLM8G1GEUF-B04Q057 is an 8GB embedded MultiMediaCard (eMMC) device built to the JEDEC eMMC 5.1 standard. It integrates Samsung 64Gb MLC NAND flash with an on-die managed-NAND controller in a single 153-ball FBGA package, presenting a simple, standardized block-storage interface to the host. The “Q” grade marks this part as a member of Samsung’s automotive eMMC product family, making it suited to harsh-environment, high-reliability embedded designs that require an extended operating temperature range.

By handling wear leveling, bad-block management, ECC, and the flash translation layer internally, this device dramatically simplifies system design compared to raw NAND, while delivering the high-speed HS400 DDR interface defined in eMMC 5.1.
