M95256-DFCS6TP/K

M95256-DFCS6TP/K is a 256Kbit serial SPI bus EEPROM in a 8 pin WLCSP package. The M95256-DF can operate with a supply voltage from 1.7 V to 5.5V, over an ambient temperature range of -40°C / +85°C. It offers an additional page, named the identification page (64 bytes). The identification page can be used to store sensitive application parameters that can be (later) permanently locked in Read-only mode.
