Grade and lifecycle
This ordering code carries the manufacturer’s wide-temperature grade designation; the qualification grade and operating-temperature band are carried by the temperature term attached to this page, and the prose here makes no further environmental-grade claim of its own.
The manufacturer catalog lists this ordering code with part status “Production”; the lifecycle field is set accordingly (Production → Active, End of Life → Obsolete).
Data source and completeness
The manufacturer part catalog prints this ordering code “MT25QU256ABA8E12-0AUT” verbatim with “Operating Temp -40C to +125C”, “I/O Voltage 1.8 VOLTS”, “Speed 166MHz”, “Part Status Code Production” and “Component Config 64Mb x4”; package “TBGA”. Device figures come from the same-manufacturer MT25QU256ABA family datasheet (md5 on file, first-party, AGG=NONE). No public datasheet hyperlink is published.
Who makes it
Micron Technology, Inc., founded 1978 and headquartered in Boise, Idaho, is the manufacturer of this serial NOR family.
