No last-time-buy window exists; the part is already out of production. ## 108 MHz clock and Quad I/O — what the speed rating means The 108 MHz clock frequency is the maximum SPI clock for Quad I/O reads. At that speed, the controller can fetch instructions or data at up to 54 MB/s (108 MHz × 4 bits). That is enough bandwidth to shadow-boot a 64 Mbit image in under 150 ms, or to stream firmware updates over the air without stalling the application. The 3 ms write cycle time per page (Word, Page) is typical for NOR — the controller must poll the status register or wait 3 ms before issuing the next write command. For OTA staging, plan a write buffer in the MCU RAM so the Flash write does not block the communication stack.","metaTitle":"S25FL164K0XBHI023 64Mbit NOR Flash, SPI Quad I/O, 108 MHz","metaDescription":"Cypress S25FL164K0XBHI023 64Mbit NOR Flash, SPI Quad I/O, 108 MHz, 2.7-3.6V, -40°C to 85°C, 24-TBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL164K0XBHI023","Series":"FL1-K","Package":"Cut Tape (CT)","Technology":"FLASH - NOR","Memory Size":"64Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"24-TBGA","Clock Frequency":"108 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL164","Memory Organization":"8M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"24-BGA (8x6)","Write Cycle Time - Word, Page":"3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a68b7e99eb04ca36ab30eedaef96990c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL164K0XBHI023 obsolete?","answer":"Yes, the S25FL164K0XBHI023 carries an Obsolete lifecycle status.

There is no direct drop-in from the original manufacturer. For a pin-compatible alternative, evaluate other 64 Mbit NOR Flash devices in the 24-TBGA package with SPI Quad I/O support from vendors like Winbond or Macronix — but verify the footprint and command set against your firmware driver before committing the BOM."},{"question":"Does S25FL164K0XBHI023 support SPI Quad I/O?","answer":"Yes, the memory interface is SPI Quad I/O.
