Grade and lifecycle

This page documents the standard device ordered with the IT operating-temperature code, rated -40C to +85C. No qualification standard or environmental grade is asserted here.

The manufacturer part catalog lists this ordering code with part status “End of Life”, so the Lifecycle field is set to Obsolete on that basis.

Data source and completeness

The catalog prints this ordering code “MT25QU128ABA8ESF-0SIT” verbatim with “Operating Temp -40C to +85C”, “I/O Voltage 1.8 VOLTS”, “Part Status Code End of Life”, “Component Config 32Mb x4” and package “SOIC” (dimension 10.30 x 10.30 x 2.65 mm). Device figures come from Micron MT25QU128ABA 128Mb 1.8V Multiple I/O Serial NOR Flash current part (aba-0; first-hand Antenna House (first-party, AGG=NONE). No public datasheet hyperlink is published (confidential manufacturer copy, not byte-verified against a hosted public file).
