AEC-Q100 qualified 128 Mbit NOR Flash for automotive and industrial designs
133 MHz Quad SPI — what it means for read throughput and pin count
The 133 MHz clock applies to both single-SPI and Quad I/O modes; in Quad I/O the effective data rate reaches 532 Mbps (133 MHz × 4 bits). That throughput supports fast code shadowing for XiP (eXecute-in-Place) or quick firmware boot from a companion MCU. The QPI mode reduces command overhead by using the same four I/O lines for address and data, which simplifies the host controller's state machine. The SPI Quad I/O interface keeps the pin count to eight — four data lines plus clock, chip select, and supply — so the 8-SOIC package fits on a two-layer board without a dense BGA escape. This matters for automotive ECU layouts where board area and layer count are tightly budgeted.
Deployment context — where the 105°C rating and AEC-Q100 matter
If the design targets a commercial or consumer application, the same silicon is available in the FL-L series with a commercial temperature grade — but this variant's qualification headroom costs nothing extra on the BOM.
Supply and sourcing — quoted to order
For a production BOM requiring an AEC-Q100 NOR Flash with a 133 MHz Quad SPI interface, the S25FL128LAGMFB013 can be specified into the line and ordered on a per-lot basis.
