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.","metaTitle":"S25FL128LAGMFI003 NOR Flash 128Mbit SPI Quad I/O, 133 MHz","metaDescription":"Cypress S25FL128LAGMFI003 FL-L series 128Mbit NOR Flash, SPI Quad I/O interface, 133 MHz clock, 2.7-3.6V, -40 to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"FL-L","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-L","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8700","priceTiers":[{"qty":1,"price":"$3.87000","currency":"USD"},{"qty":10,"price":"$3.51100","currency":"USD"},{"qty":25,"price":"$3.43440","currency":"USD"},{"qty":50,"price":"$3.41580","currency":"USD"},{"qty":100,"price":"$3.06260","currency":"USD"},{"qty":250,"price":"$3.05148","currency":"USD"},{"qty":500,"price":"$2.93998","currency":"USD"},{"qty":1450,"price":"$2.79503","currency":"USD"},{"qty":2900,"price":"$2.76530","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128LAGMFI003/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL128LAGMFI003 obsolete or active?","answer":"The product status is active."},{"question":"What is the clock frequency of S25FL128LAGMFI003?","answer":"The SPI clock frequency is 133 MHz.
