KLM4G1FETE-B041001 – eMMC 5.1 – Samsung

The Samsung KLM4G1FETE-B041001 is a 4GB eMMC 5.1 managed NAND device in a 153-ball FBGA package with an HS400 high-speed interface, ideal for embedded and mobile storage designs.

The Samsung KLM4G1FETE-B041001 is a 4GB eMMC 5.1 embedded storage device that integrates NAND flash memory with an on-chip MultiMediaCard controller in a single, compact 153-ball FBGA package. By handling wear leveling, bad-block management, and ECC internally, this managed-NAND solution simplifies host design and shortens time to market for space-constrained embedded systems. It supports the high-speed HS400 interface defined in the JEDEC eMMC 5.1 standard, delivering reliable, low-power non-volatile storage for an operating system, firmware, and user data.
