KLMCG4JEUD-B04Q058 – eMMC 5.1 64GB Managed NAND – Samsung

The Samsung KLMCG4JEUD-B04Q058 is a 64GB automotive-grade eMMC 5.1 embedded managed-NAND device in a 153-ball FBGA package, integrating MLC NAND flash and an MMC controller with the HS400 interface for embedded storage applications.

The Samsung KLMCG4JEUD-B04Q058 is a 64GB embedded multimedia card (eMMC) compliant with the JEDEC eMMC 5.1 standard. It belongs to Samsung’s KLMCG4JEUD-B04Q family of automotive managed-NAND devices, combining 128Gb MLC NAND flash (organized as 128Gb x 4) with an integrated MMC controller in a single 153-ball FBGA package. By managing wear leveling, ECC, and bad-block handling on-chip via the Flash Translation Layer, eMMC simplifies host-side firmware and accelerates time-to-market for embedded designs.

This device supports the high-speed HS400 mode (200MHz DDR) and uses a dual-supply scheme: a memory-core supply (VDDF / VCC) rated 2.7V to 3.6V for the NAND, and an interface supply (VDD / VCCQ) selectable at 1.70V-1.95V or 2.7V-3.6V for the controller/host interface. The B04Q part is AEC-Q100 compliant and rated for an automotive case-temperature range of -40°C to +105°C, making it well suited to industrial and automotive-grade embedded systems.
