MX29GL128FLT2I-90G

MX29GL128FLT2I-90G overview

MX29GL128FLT2I-90G is a 128Mbit, 3V page-mode Parallel NOR Flash device supporting x8 and x16 bus configurations. The exact ordering code specifies 90 ns access, an industrial-temperature range and the 56-TSOP package.

The L device option uses lowest-address-sector protection when WP# is asserted low. That protection behavior, the selected bus width and the package pinout should all be checked during design or replacement review.

Key technical specifications

Sourcing review

Confirm the x8/x16 configuration, sector-protection behavior, speed grade, package, date-code restrictions, qualification and traceability. Availability and delivery terms are determined through an RFQ review.

Design and replacement checks

MX29GL128FLT2I-90G selection should be reviewed at the full ordering-code level. Confirm the 128 Mbit density, 3 V supply class, x8 or x16 bus configuration, 90 ns timing, 56-TSOP footprint and industrial temperature range against the board design. Firmware and boot code should also be checked for sector layout, command-set, protection and status-register assumptions.

For replacement analysis, do not rely on density alone. A candidate must match the parallel interface, pinout, access timing, sector organization and WP# protection behavior required by the application. An RFQ should include the exact MPN, required quantity, packing preference, acceptable date codes, traceability requirements and delivery location so that availability can be evaluated without silently changing the speed, package or protection option.
