8Kbit SPI EEPROM in 8-SOIC — 5V operation, 10 MHz bus
The M95080-MN6T is an 8Kbit serial EEPROM from STMicroelectronics, organized as 1K x 8 bits and accessed via an SPI bus running up to 10 MHz.
The 8Kbit SPI EEPROM market includes many functional equivalents, but a pin-compatible drop-in from another vendor would require verifying the SPI command set and write-cycle timing against the original design.
Write-cycle timing and firmware update planning
The write cycle time per word or page is 5 ms (typical). For a 1K x 8 memory, a full-chip write (sequentially writing all 1024 bytes) would take roughly 5.1 seconds at one byte per write cycle, assuming no page write mode acceleration. This sets a floor for firmware update or parameter storage intervals — a field update that rewrites the entire array must budget for several seconds of uninterrupted write time.
