The 66 MHz clock rate with Quad I/O (four data lines) gives a sustained read throughput that can feed an automotive MCU's execute-in-place (XIP) or shadow-to-RAM boot flow without stalling the core. If your application uses the SPI bus for firmware shadowing or over-the-air update staging, the 66 MHz Quad I/O keeps the transfer window short. The same interface is backward-compatible with single and dual SPI, so it drops into an existing SPI Flash socket without firmware changes — you just leave the extra pins unconnected if the host doesn't support Quad. The AEC-Q100 qualification and -40 to 105 °C operating temperature tell you this part was characterised for the thermal cycling and reliability demands of automotive under-hood and chassis domains. For industrial or outdoor telecom designs that don't require the full AEC paperwork, the temperature range alone still covers most extended-environment cases. ## 24-TBGA footprint — rework and inspection considerations Solder joints are not visually inspectable — X-ray is the standard for void and alignment check. If your rework station doesn't have a pre-heater and a hot-air nozzle sized for this body, the adjacent passives can shift during removal. The base product number S25FL128 covers a family of density and package variants; if your procurement team wants a second-source hedge, the S25FL128SDPBHA303 (same die, different package code) is a direct replacement candidate — confirm the package suffix matches your footprint before swapping.","metaTitle":"S25FL128SDPBHB303 128 Mbit NOR Flash, AEC-Q100, 66 MHz SPI","metaDescription":"Infineon/Cypress S25FL128SDPBHB303 128 Mbit NOR Flash, SPI Quad I/O, 66 MHz, 2.7-3.6 V, -40 to 105 °C, 24-TBGA, AEC-Q100.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL128SDPBHB303","Series":"Automotive, AEC-Q100, FL-S","Package":"Tape & Reel (TR)","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"24-TBGA","Clock Frequency":"66 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":"24-BGA (6x8)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5318","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL128SDPBHB303 a direct replacement for S25FL128SDPBHA303?","answer":"The S25FL128SDPBHA303 shares the same die and electrical characteristics — the difference is in the package suffix.
