What this document says about grade and variants
This page documents only the standard device ordered with the IT operating-temperature code, rated from -40°C to +85°C. The ordering chart in the datasheet lists the family across several densities, voltages, I/O boot configurations and further operating-temperature codes as separate part numbers; higher-temperature and ruggedised wide-temperature variants are distinct ordering codes and are not claimed for this device. No qualification standard or environmental grade is asserted here — the reliability figures above are the datasheet’s own endurance and retention numbers, not an environmental grade.
Data source and completeness
Figures are taken from the manufacturer datasheet MT35X 256Mb, 1.8V Octal I/O Serial NOR Flash (Xccela family) datasheet — Rev. G 05/2026 (©2016 Micron Technology, Inc.)，md5 802b719e99b5668d2c2bc8f81adfbfff. This is the manufacturer’s confidential-formatted copy, so no public datasheet link is claimed; the manufacturer product page is the reference. The datasheet gives no application list and no lifecycle/end-of-life status for this ordering code, so those fields are intentionally left blank rather than inferred.
Who makes it
MT35XU256ABA1G12-0SIT is made by Micron Technology, Inc., which began in 1978 in Boise, Idaho and is the maker of the Xccela serial flash line. ©2016 Micron Technology, Inc.
