K4F4E3S4HF-MGCJ – LPDDR4 SDRAM – Samsung
Samsung K4F4E3S4HF-MGCJ is a 4 Gb LPDDR4 mobile SDRAM organized as 128M x 32, rated to 3733 Mbps in a 200-ball FBGA package. An obsolete, hard-to-find part available for quote from Pacific Component Xchange.
The Samsung K4F4E3S4HF-MGCJ is a 4 Gb Low-Power DDR4 (LPDDR4) mobile SDRAM device. It is organized as 128M x 32 and built on Samsung’s low-power mobile DRAM architecture, delivering high bandwidth at reduced power for space- and battery-constrained designs. The device operates at data rates up to 3733 Mbps and is housed in a compact 200-ball FBGA package, making it well suited for handheld, embedded, and edge computing platforms.
This part carries the -MGCJ order suffix, which corresponds to a commercial operating temperature range of -25 °C to +85 °C. Samsung also offers wider-temperature variants of the same K4F4E3S4HF die under other suffixes (for example -GFCJ at -40 to 95 °C) for designs requiring extended industrial thermal coverage.
