MT35XU01GBBA1G12-A0SIT

The MT35XU01GBBA1G12-A0SIT is a 1Gb (128 MB) Octal I/O serial NOR flash device in Micron’s Xccela family, catalog-listed with an 1.8V I/O supply and an x8 bus in a 24-ball T-PBGA package (6.00 x 8.00 x 1.20 mm body).

Key figures from the manufacturer page

• Interface: SPI-compatible Xccela bus, Octal protocol, JEDEC xSPI standard compliant.
• Speed: catalog speed 400MHz (400MTPS).
• Component configuration: 128Mb x8; the package carries 2 component(s) per the catalog.
• Package: TBGA, package type “GREEN”, 24-ball T-PBGA footprint per the family datasheet ordering chart.

Provenance: the manufacturer catalog page prints this ordering code verbatim as “MT35XU01GBBA1G12-A0SIT” with “Operating Temp -40C to +85C”, “I/O Voltage 1.8 VOLTS”, “Speed 400MHz” (400MTPS), “Part Status Code Production” and “Component Config 128Mb x8”; package “TBGA”, package type “GREEN”.

The manufacturer catalog lists this ordering code with part status “Production” (captured 2026-10-26). No stock, lead-time or pricing claim is made here.

Grade and qualification

This ordering code belongs to the manufacturer’s enhanced-serial-flash (SCCR) variant set of the MT35X family. The manufacturer’s qualification document covering these thirteen codes is the MT35X SCCR Addendum (PDF, Updated 2026-01-16), which the product page lists for this part; the local intake holds that addendum for verification. The qualification grade and the operating-temperature band shown above are carried by the temperature designation attached to this page; the prose here makes no further environmental-grade claim of its own.

Data source and completeness

Figures are taken from the manufacturer’s own part-detail page for this ordering code (rendered capture 2026-10-26). The family datasheet listed on that page is “Micron Xccela™ Flash Memory 1.8V, Octal I/O, 4KB, 32KB, 128KB, Sector Erase” (PDF, Updated 2026-06-08); the manufacturer’s confidential-formatted copy is not republished here, so no datasheet download link is claimed. The page gives no application list, so that field is intentionally left blank rather than inferred.
