For designs that shadow code to RAM at boot, the faster read speed shortens the startup time. The interface uses four I/O lines for data, so the PCB trace routing needs matched lengths on the four data lines to maintain signal integrity at this frequency. The FL-S series is an established Infineon product line with broad distribution support.","metaTitle":"S25FL256SAGMFIG03 256Mbit NOR Flash, SPI Quad I/O, 133 MHz","metaDescription":"S25FL256SAGMFIG03 from Infineon FL-S series: 256Mbit NOR Flash, SPI Quad I/O at 133 MHz, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"FL-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"FLASH - NOR","Memory Size":"256Mbit","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":"S25FL256","Memory Organization":"32M 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":"$5.8400","priceTiers":[{"qty":1,"price":"$5.84000","currency":"USD"},{"qty":10,"price":"$5.32700","currency":"USD"},{"qty":25,"price":"$5.22480","currency":"USD"},{"qty":50,"price":"$5.18700","currency":"USD"},{"qty":100,"price":"$4.65440","currency":"USD"},{"qty":250,"price":"$4.63692","currency":"USD"},{"qty":500,"price":"$4.34586","currency":"USD"},{"qty":1450,"price":"$4.16248","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL256SAGMFIG03/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between S25FL256SAGMFIG03 and S25FL128SAGMFIG03?","answer":"The primary difference is memory density: the S25FL256SAGMFIG03 offers 256 Mbit, while the S25FL128SAGMFIG03 is the 128 Mbit variant. Both share the same FL-S series, SPI Quad I/O interface, 133 MHz clock, supply range, and 16-SOIC package. The density choice depends on the firmware image size and data storage requirements."},{"question":"Can S25FL256SAGMFIG03 replace S25FL256SAGMFIG01?","answer":"The S25FL256SAGMFIG01 is a sibling in the same FL-S series with identical 256 Mbit density, 133 MHz clock, and Quad-SPI interface. The suffix difference typically indicates packaging or temperature grade — the FIG03 is the Tape & Reel variant with industrial temperature range. Check the specific suffix details for your BOM; if the package and temperature grade match, it is a direct replacement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL256SAGMFIG03","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL256SAGMFIG03 when reusing this data.
