For new designs or volume production, you will want a pin-compatible replacement — see the FAQ for the closest family alternative. That is fast enough to feed a Cortex-M or entry-level application processor without stalling on instruction fetches, as long as the layout keeps the SPI trace length short and the decoupling tight around the 24-ball BGA. The 5 µs word write time and 3 ms page write time are typical for this NOR generation — fine for firmware updates over a slow link, but not for high-frequency data logging. ## 24-ball BGA — rework bench notes The 24-TBGA package measures 6 x 8 mm with a 0.8 mm ball pitch. That pitch is hand-reworkable with a decent hot-air station and a stencil, but the BGA needs a bake at 125°C for 24 hours if the moisture-barrier bag has been open longer than the floor-life window — MSL 3 is typical for this package class. The 24-ball footprint saves board area versus an SOIC-16, but you lose the ability to probe signals easily; bring out the SPI lines to test pads if the board goes through a repair loop.","metaTitle":"S25FL129P0XBHV303 NOR Flash, 128Mbit, SPI Quad I/O, 104 MHz","metaDescription":"Cypress S25FL129P0XBHV303 128Mbit NOR Flash, SPI Quad I/O at 104 MHz, 2.7-3.6V, -40°C to 105°C, 24-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL129P0XBHV303","Series":"FL-P","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":"104 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL129","Memory Organization":"16M x 8","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"24-BGA (6x8)","Write Cycle Time - Word, Page":"5µs, 3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccb237c2a38e68c2a9dc926a949a53f9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for S25FL129P0XBHV303?","answer":"The closest pin-compatible alternative within the same Cypress FL-P family is the S25FL128P0XBHV303. Both parts share the same 24-ball BGA footprint, SPI Quad I/O interface, voltage range, and temperature grade. The key difference is density: the S25FL128P0XBHV303 is 128 Mbit — the same capacity — so it is a direct functional replacement.
