Product details

The Micron MT25QL128ABA1EW9-0SIT is a 128 Mbit serial NOR Flash memory using the SPI - Quad I/O interface, clocked at 133 MHz.

133 MHz clock — what it means for read throughput

Standard SPI at the same clock would deliver one-quarter the throughput because Quad I/O transfers four bits per cycle. If your design currently runs a dual-I/O NOR at 133 MHz, this part doubles the read rate without changing the PCB footprint — the pinout is the same 8-pin WDFN.

For BOM planning, the MT25QL128ABA1EW9-0SIT is a current-production line item with no imminent supply discontinuity. The ROHS3 compliance means it ships without restricted substances under current EU exemptions.

That covers industrial control cabinets and outdoor telecom shelters.

Frequently asked questions

What is the voltage supply range for MT25QL128ABA1EW9-0SIT?

The supply voltage range is 2.7 V to 3.6 V, which is the standard 3.3 V logic rail with margin for brownout and overvoltage.

What is the operating temperature range of MT25QL128ABA1EW9-0SIT?

The operating temperature range is -40°C to 85°C, suitable for industrial and telecom environments.

What are the packaging options for MT25QL128ABA1EW9-0SIT?

This specific variant ships in a Tray. For Tape & Reel, use the MT25QL128ABA1EW9-0SIT TR variant.

Can MT25QL128ABA1EW9-0SIT be a direct replacement for other Micron NOR Flash?

Yes, it is pin-compatible with other 8-pin WDFN MT25Q family parts of the same density. The Quad I/O interface is backward-compatible with standard SPI and dual-I/O protocols.
