The 133 MHz quad-SPI clock means the effective read bandwidth is roughly 532 Mbit/s in quad mode — enough to feed a Cortex-M or entry-level application processor without stalling on instruction fetches. The QPI mode reduces the command overhead by letting the opcode itself go over the four I/O lines, which tightens the latency on random reads. ## Supply rail and temperature — where this part fits the BOM That margin matters if your board has a long power cable drop or a shared 3.3 V bus with other loads that pull it down during transients. It is not rated for the 105°C or 125°C extended ranges that some under-hood automotive or downhole applications require. The package is a 16-SOIC with 0.295-inch body width (7.50 mm), surface-mount. For a BOM planner, this removes the urgency to stockpile or qualify a replacement. ## How it compares to the FL-S series and the extended-temperature sibling The closest peer within the same Infineon portfolio is the S25FL256SAGMFIR01, which is also a 256 Mbit NOR Flash in a 16-SOIC tube, but from the FL-S series. The FL-L series adds the QPI protocol, which can reduce command overhead on random-access patterns.","metaTitle":"Infineon S25FL256LAGMFI001 256Mbit NOR Flash, 133 MHz SPI","metaDescription":"Infineon S25FL256LAGMFI001 256Mbit FL-L series NOR Flash in 16-SOIC.
