K4U8E3S4AD-MGCL – LPDDR4X SDRAM – Samsung

The Samsung K4U8E3S4AD-MGCL is a 12Gb low-power LPDDR4X SDRAM with x32 organization, 4266Mbps data rate, in a 200-ball FBGA package. Available now for RFQ at Pacific Component Xchange.

The Samsung K4U8E3S4AD-MGCL is a Low-Power DDR4X (LPDDR4X) mobile SDRAM from Samsung’s K4U series, engineered for power-efficient, high-bandwidth memory in smartphones, tablets, and compact embedded platforms. It provides 12Gb of density with a 4266 Mbps data rate and a 32-bit (x32) interface in a space-saving 200-ball FBGA package, making it well suited to designs where board area and power budget are constrained.

As part of Samsung’s LPDDR4X portfolio, the K4U8E3S4AD-MGCL uses a reduced VDDQ I/O rail (0.6 V) to cut interface power versus standard LPDDR4 while maintaining JEDEC-compliant performance. With Samsung now winding down LPDDR4X production, this device is increasingly difficult to source through authorized channels, making it a priority part for buyers maintaining existing designs.
