That means no further production runs; the only channel is surplus inventory or broker stock. For an existing BOM, a last-time buy may have already closed — verify date codes and remaining shelf life before committing to a large reel. ## 32 Mbit NOR Flash with 108 MHz Quad I/O — what it delivers The S25FL132K0XNFI043 is a 32 Mbit (4 M x 8) SPI NOR Flash from Cypress's FL1-K series. It supports Quad I/O at a clock frequency of 108 MHz, which gives a practical read throughput high enough for execute-in-place (XIP) firmware on a moderate-speed MCU. ## Industrial temperature range — where it works The 3 ms page write cycle time is standard for NOR; it governs the firmware-update speed during OTA or in-system programming.","metaTitle":"S25FL132K0XNFI043 32Mbit SPI NOR Flash, 108 MHz Quad I/O","metaDescription":"S25FL132K0XNFI043 is a 32Mbit SPI NOR Flash from Cypress FL1-K series, 108 MHz Quad I/O, 2.7-3.6V, 8-SOIC, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL132K0XNFI043","Series":"FL1-K","Package":"Tape & Reel (TR)","Technology":"FLASH - NOR","Memory Size":"32Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"108 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL132","Memory Organization":"4M x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-SOIC","Write Cycle Time - Word, Page":"3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1fd19ebea1d138715df21d570700e895.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL132K0XNFI043/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL132K0XNFI043 obsolete and what is its replacement?","answer":"Yes, Cypress lists the S25FL132K0XNFI043 as Obsolete.
