Overview
The M95M02-DRMN6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is organized as 262144 x 8 bits, providing a total of 2 Mbits (256 Kbytes) of EEPROM memory. This device is accessed through the Serial Peripheral Interface (SPI) bus, making it compatible with a wide range of microcontrollers and other SPI-compatible devices.
The M95M02-DRMN6TP operates over a temperature range of -40 °C to +85 °C with a supply voltage of 1.8 to 5.5 V. It also features an additional 256-byte Identification page that can be used to store sensitive application parameters and can be permanently locked in read-only mode.
