The 1.5 ms typical page write time sets the floor for firmware-update cycles: writing a full 64 Mbit at 256-byte pages takes about 48 seconds, plus erase overhead, so an OTA update strategy should budget for that window. The SPI interface supports standard, dual, and quad I/O commands — the quad mode requires four data lines (IO0-IO3) plus the chip select and clock, which ties up six GPIOs on the host controller. ## Temperature grade and deployment context The non-volatile FLASH technology retains data across power cycles — no battery backup needed for configuration storage or calibration constants in a field-deployed system.","metaTitle":"SST26WF064C-104I/MF 64Mbit FLASH, SPI Quad I/O, 104 MHz","metaDescription":"Microchip SST26WF064C-104I/MF 64Mbit SPI Quad I/O FLASH, 104 MHz clock, 1.65-1.95V, industrial temp, 8-WDFN.
