That clock rate, combined with the quad data lines, gives a read throughput that keeps an MCU fed during execute-in-place (XIP) boot or over-the-air update staging — the 128 Mbit density holds a substantial firmware image plus a config or log partition. ## Package and mounting — 8-SOIC wide-body Housed in an 8-SOIC wide-body package (5.30 mm body width), surface-mount soldered. The 8-pin footprint is a common NOR Flash layout shared across many 128 Mbit parts from multiple vendors, which simplifies second-sourcing or a last-minute swap. ## Lifecycle status — active, no near-term LTB risk The FL-S series is a mature, widely deployed NOR Flash family, so supply continuity through the independent channel is stable.","metaTitle":"S25FL127SABMFB103 128 Mbit NOR Flash, 108 MHz Quad-SPI","metaDescription":"Cypress S25FL127SABMFB103 FL-S series 128 Mbit NOR Flash, 108 MHz SPI/Quad I/O, 2.7-3.6V, -40 to 105°C, 8-SOIC.

The FB103 variant is Tape & Reel. Electrically and footprint-wise they are interchangeable, but verify the specific suffix meaning against the manufacturer's ordering guide for your assembly process."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL127SABMFB103","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL127SABMFB103 when reusing this data.
