K4UBE3D4AB-MGCL – LPDDR4X SDRAM – Samsung

The Samsung K4UBE3D4AB-MGCL is a 32 Gb LPDDR4X mobile SDRAM in a 200-ball FBGA package, rated for data rates up to 4266 Mbps. This part has been discontinued by Samsung and is available for RFQ from Pacific Component Xchange.

The Samsung K4UBE3D4AB-MGCL is a 32 Gbit (4 GB) low-power LPDDR4X SDRAM device engineered for high-bandwidth, energy-efficient operation in mobile and embedded platforms. Built on Samsung’s LPDDR4X technology, it delivers higher performance than standard LPDDR4 while reducing I/O power through a lower 0.6 V VDDQ supply, making it a preferred memory choice for space- and power-constrained designs. The 32 Gb density is internally configured as 16 Gb x 2 in a dual-channel architecture.

Supplied in a compact 200-ball FBGA package, the K4UBE3D4AB-MGCL supports data transfer rates up to 4266 Mbps (2133 MHz clock) using a double-data-rate architecture with two data transfers per clock cycle. Industry-standard JEDEC LPDDR4X features such as auto self-refresh, auto precharge, write leveling, data mask, asynchronous reset, and ZQ calibration ensure robust, reliable integration into modern system designs.
