Description
The M95M02 devices are electrically erasable programmable memory (EEPROM) organized as 262144 x 8 bits,
accessed through the SPI bus.
Over an ambient temperature range of -40 °C / +85 °C the M95M02-DR can operate with a supply voltage from
1.8 to 5.5 V. Over an ambient temperature range of -20 °C / +85 °C the M95M02-DF can operate with a supply
voltage from 1.7 to 5.5 V.
The M95M02 devices offer an additional page, named the Identification page (256 bytes). The Identification page
can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode.
