Overview
The M95256-DFMC6TG is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is organized as 32768 x 8 bits and is accessed through the Serial Peripheral Interface (SPI) bus. This device operates within a supply voltage range of 1.7 V to 5.5 V and is designed to function over an ambient temperature range of -40 °C to +85 °C. The M95256-DFMC6TG features an additional write lockable page known as the Identification page, which can store sensitive application parameters and be permanently locked in read-only mode.
