Overview
The M95256-RMN6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is part of the M95256 series, which are organized as 32768 x 8 bits and accessed through the SPI bus. This device operates with a supply voltage from 1.8 V to 5.5 V and is designed to function over an ambient temperature range of -40 °C to +85 °C. The M95256-RMN6TP 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.
