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.
