MT53E256M32D2FW-046 IT:B is a 8Gb LPDDR4/LPDDR4X SDRAM in a 256Mb x32 configuration (D2 die x32), on the -046 speed grade (4266 Mb/s/pin), VDD1 = 1.8 V with VDD2/VDDQ = 1.10 V or 0.60 V low-VDDQ option, in a 200-ball TFBGA package (10.00 x 14.50 x 1.10, package code FW), revision :B. Operating temperature range: -40C to +95C.
Key figures
- Configuration: 256Mb x32 per die; D2 (8Gb).
- Speed: -046 = 4266 Mb/s/pin.
- Supply: VDD1 = 1.8 V; VDD2/VDDQ = 1.10 V or 0.60 V.
- Package: 200-ball TFBGA, 10.00 x 14.50 x 1.10 (package code FW); revision :B.
- Operating temperature range: -40C to +95C.
Temperature and lifecycle
The manufacturer part catalog lists this ordering code’s operating range as -40C to +95C, and its part status as "Production", so the Lifecycle field is set to Active on that basis.
Source and datasheet link
Device figures come from Micron 200-ball x16/x32 LPDDR4/LPDDR4X SDRAM current commercial/industrial-grade part (first-hand micron-ds-fo.xsl, the document body is marked manufacturer-confidential, AGG=NONE; Figure1 explicitly marks the option bit: A = package-level burn-in, blank = standard; this part number carries no A option, so it is not vehicle-grade) + Micron lpddr4 part-catalog export (2026-11-02); the operating-temperature band and supply status come from the manufacturer part catalog. No public datasheet hyperlink is published (this is a confidential manufacturer copy, not byte-verified against a hosted public file).
Who makes it
Micron Technology, Inc., founded 1978 and headquartered in Boise, Idaho, is the manufacturer of this LPDDR4/LPDDR4X family.
