NOR flash is typically used for code storage and execute-in-place (XIP) applications in embedded systems, where random-access read speed and reliability matter more than density. The 64 Mbit capacity fits firmware images for microcontrollers, boot loaders, and configuration data in industrial or networking gear. The 8-WSON package (5x6 mm body) with an exposed pad helps conduct heat into the PCB copper plane. ## Write cycle and page programming Page write cycle time is 3 ms typical. This means programming a 256-byte page takes 3 ms, so a full 64 Mbit firmware update (8 MB) would take roughly 96 seconds at the page level, not counting overhead for sector erase and command sequences. Budget this into the field update window. The SPI Quad I/O interface reads four bits per clock cycle, quadrupling the throughput over standard SPI at the same clock rate. At 108 MHz, the quad read throughput is about 54 MB/s, which is fast enough for XIP of code from flash without shadowing to RAM. ## Obsolete — sourcing through independent channels Because no pin-compatible replacement is recorded, a board redesign may be required to migrate to a current NOR flash part. The functional replacement would need to match the 64 Mbit density, SPI Quad I/O interface, 2.7-3.6 V supply, and 8-WSON footprint — a parametric search against those constraints is the next step.","metaTitle":"Infineon S25FL164K0XNFIQ11 64Mbit NOR Flash, SPI Quad I/O","metaDescription":"Infineon S25FL164K0XNFIQ11 64Mbit NOR Flash, SPI Quad I/O, 108 MHz, 2.7V-3.6V, -40°C to 85°C, 8-WSON.
