It speaks SPI with Quad I/O and QPI support, hitting a 133 MHz clock rate for fast read throughput.
At 133 MHz with Quad I/O, this part can sustain read throughput well above 50 MB/s in burst mode. That matters for direct code execution (XIP) from NOR Flash — the CPU doesn't stall waiting for the memory bus. The QPI mode reduces command overhead by using the same four I/O lines for address and data, cutting latency on random reads. If your MCU or SoC has a Quad SPI controller, this part lets you keep the firmware in-place without a separate DRAM for shadowing.
That means no last-time-buy notice looming, and it's qualified for new production designs. ROHS3 compliant. For long-term supply planning, the FL-L series is a mature, stable line — Infineon (formerly Cypress) continues to support it. If you need a wider temperature range, the sibling S25FL128LAGMFV013 extends to 105°C, but the 'FI003 stays at the standard industrial ceiling.
16-SOIC — rework-friendly footprint
Housed in a 16-SOIC (7.50 mm width) package, this is a rework-friendly part. The gull-wing leads are easy to inspect and hand-solder if needed. No exposed pad means you don't have to worry about thermal vias or solder paste coverage underneath — just a straightforward footprint. The wide body also gives decent creepage for the 3.6 V supply rail.
