The 24-TBGA package (6x8 mm) keeps the footprint compact for space-constrained designs. If you are qualifying this for a production BOM, plan for a last-time-buy or a validated replacement. ## 66 MHz clock and Quad SPI — what the interface means for throughput The 66 MHz clock rate with Quad I/O (four data lines) gives a theoretical peak read throughput of 264 Mbps (66 MHz x 4 bits). In practice, the controller overhead and command overhead reduce that, but it still offers a significant speed advantage over standard SPI at the same clock. The QPI mode allows the command and address to also use the four I/O lines, reducing instruction overhead. For a firmware engineer, this means faster code shadowing to RAM and quicker OTA update staging compared to a single-bit SPI NOR Flash running at the same frequency. ## Package and temperature — design-in checklist The 24-TBGA (6x8 mm) package is a fine-pitch BGA. The PCB layout needs a via-in-pad or microvia strategy for the inner balls; the datasheet's recommended land pattern should be followed exactly.","metaTitle":"S25FL256LDPBHN033 256 Mbit NOR Flash, 66 MHz, Quad SPI","metaDescription":"S25FL256LDPBHN033 is a 256 Mbit NOR Flash from the FL-L series, 66 MHz clock, Quad SPI interface, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-L","Package":"Tape & Reel (TR)","Technology":"FLASH - NOR","Memory Size":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"24-TBGA","Product Status":"Obsolete","Clock Frequency":"66 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"24-BGA (6x8)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bf25acfe331e51d6917f0712f2b10471.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for S25FL256LDPBHN033?","answer":"For a pin-compatible replacement, check the S25FL256L family from Cypress/Infineon — parts with similar density, package, and interface may be available as active alternatives.
