4 Gbit LPDDR4 in a 10×14.5 mm BGA
The MT53E256M16D1DS-046 WT:B is a 4 Gbit Mobile LPDDR4 SDRAM organized as 256M x 16, clocked at 2.133 GHz and running from a 1.1 V core supply. It ships in a 200-ball WFBGA package measuring 10×14.5 mm — the footprint and ball map match the JEDEC LPDDR4 standard, so the layout transfers across density upgrades within the same package code.
Memory density and bus width for the BOM
At 4 Gbit with a x16 data bus, this part delivers 512 MB per package. The 2.133 GHz clock rate corresponds to a 4266 MT/s data rate on the double-data-rate bus — the controller PHY must support that speed grade to close timing on the fly. The operating temperature range is -30°C to 85°C (TC), which covers the industrial envelope for most portable and embedded systems. The 1.1 V supply keeps the I/O and core on the same rail, simplifying the power tree.
Active production, RoHS3 compliant
The tray delivery format is standard for BGA devices in volume production.
