Temperature and lifecycle
The manufacturer part catalog lists this ordering code’s operating range as -30C to +85C. Its part status is "Contact Sales", which the catalog does not map to a public offer-status term, so the Lifecycle field is left blank and tracked for a manufacturer PCN.
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.
