The M95080-RMB6TG is an 8-Kbit serial EEPROM from STMicroelectronics, organized as 1K × 8 bits and accessed over an SPI bus running at up to 10 MHz.
Obsolete status — what it means for supply and the replacement path
STMicroelectronics lists the M95080-RMB6TG as Obsolete, though the spec table carries a 'current' lifecycle flag — the official manufacturer status overrides the catalog record.
Write-cycle timing and the 5 ms page-program window
For a data-logging application writing one 8-bit word every 10 seconds, the EEPROM spends 0.05 % of its time in the write cycle — the rest is read-idle. The 5 ms window also sets the minimum SPI bus idle time between write commands; a host that polls the status register for the WIP bit must wait at least this long before the next write cycle starts.
Package and board-fit: 8-UFDFPN exposed pad
The exposed pad on the underside requires a thermal land on the PCB — the datasheet's recommended land pattern keeps the junction temperature within the −40 to 85 °C operating range at the 10 MHz clock rate.
