The 133 MHz clock rate gives a theoretical throughput edge over older single-SPI parts, though real-world gain depends on the controller's Quad SPI peripheral and board layout. ## Package and footprint — what you need to know for layout Housed in a 16-pin SOIC with 7.50 mm body width (the 0.295-inch wide version), surface-mount only. The 16-SOIC is a common footprint for NOR Flash — same as many 128 Mbit and 256 Mbit parts from other vendors — so a layout swap between suppliers is often a straight drop-in. ## Where it fits in a design Typical use cases: code storage for a microcontroller or SoC that boots from SPI NOR, configuration data for an FPGA, or firmware-over-the-air staging area. The 128 Mbit capacity is a common sweet spot — enough for a full Linux kernel or a hefty application image, without the cost jump to 256 Mbit or 512 Mbit parts.","metaTitle":"S25FL128SAGMFVG00 NOR Flash 128 Mbit, SPI Quad I/O, 133 MHz","metaDescription":"S25FL128SAGMFVG00 128 Mbit NOR Flash from Cypress, SPI Quad I/O interface at 133 MHz, -40°C to 105°C, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tray","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","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1570","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL128SAGMFVG00 compatible with 3.3V systems?","answer":"The SPI I/O levels are also 3.3 V tolerant, so no level shifting needed for most 3.3 V controllers."},{"question":"What is the closest pin-compatible alternative to S25FL128SAGMFVG00?","answer":"Within the same Cypress FL-S family, the S25FL128SAGMFI00 shares the same 16-SOIC footprint, 128 Mbit density, and Quad SPI interface.
