Overview
The M95080-RDW6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. It is organized as 1024 x 8 bits and is accessed through the Serial Peripheral Interface (SPI) bus. This device is part of the M95080 series, which includes variants with different supply voltage ranges. The M95080-R specifically 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. It features an additional write lockable identification page, making it suitable for storing sensitive application parameters that can be permanently locked in read-only mode.
