K4UBE3D4AB-KFCL – LPDDR4X SDRAM – Samsung

The Samsung K4UBE3D4AB-KFCL is a 32Gb (DDP) LPDDR4X mobile SDRAM rated at 4266Mbps in a 200-ball FBGA package, with an extended -40 to 95°C operating temperature grade.

The Samsung K4UBE3D4AB-KFCL is a 32-gigabit (32Gb) Low-Power DDR4X (LPDDR4X) mobile SDRAM device built in a dual-die package (DDP) configuration. Each die is organized as 128Mb x 16DQ x 8 banks x 2 channels, giving the device a x32 overall organization across two channels per die. It is packaged in a space-efficient 200-ball fine-pitch ball grid array (FBGA) measuring 10 x 15 mm, making it well suited to compact, power-sensitive embedded and mobile designs.

The “KFCL” suffix designates the extended -40 to +95°C operating temperature grade, making this variant a strong fit for automotive, industrial, and other harsh-environment applications that standard commercial mobile DRAM cannot serve. This is an end-of-life / discontinued Samsung part, which makes long-term supply through authorized channels difficult.
