2 Mbit serial SPI bus EEPROM

The M95M02 devices are Electrically Erasable PROgrammable Memories (EEPROMs) organized as 262144 x 8 bits, accessed through the SPI bus.

The M95M02 can operate with a supply range from 1.8 V to 5.5 V. These devices are guaranteed over the -40 °C/+85 °C temperature range.

The M95M02-DR offers an additional page, named the Identification Page (256 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
