Overview
The M95M01-DFDW6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is organized as 131072 x 8 bits, providing 1 Mbit (128 Kbytes) of EEPROM memory. This device is accessed through the serial peripheral interface (SPI) bus, making it compatible with a wide range of applications. The M95M01-DFDW6TP operates within a supply voltage range of 1.7 V to 5.5 V and is guaranteed over an operating temperature range of -40 °C to +85 °C. An additional 256-byte identification page is available for storing sensitive application parameters, which can be permanently locked in read-only mode.
