Frequently asked questions

What is the voltage supply range of MT25QU128ABA1ESE-0SIT?

The supply range is 1.7 V to 2 V. This is a 1.8 V nominal part, designed to run directly from a 1.8 V rail without an extra regulator.

What is the package and pinout of MT25QU128ABA1ESE-0SIT?

It comes in an 8-pin SOIC package (8-SO, 5.30 mm body width). Pin 1 is marked by a dot and a bevel. The pinout is standard for SPI NOR Flash: CS#, CLK, DI, DO, WP#, and HOLD#.

Is MT25QU128ABA1ESE-0SIT RoHS compliant?

Yes, it is rated ROHS3 Compliant.

What are alternatives or equivalents to MT25QU128ABA1ESE-0SIT?

For a 3.3 V system, the pin-compatible MT25QL128ABA1EW9-0SIT TR is the direct equivalent with the same 133 MHz Quad SPI interface. For automotive 105°C applications, the MT25QL128ABA8ESF-0AAT TR (AEC-Q100) is the alternative, though it also requires a 2.7 V to 3.6 V supply.
