ST M95020-RDW6TP

The M95010/ M95020/M95040 devices (M950x0) are electrically erasable programmable memories (EEPROMs) organized as 128/256/512x8 bits respectively, accessed through the SPI bus. The M950x0-W can operate with a supply voltage from 2.5 V to 5.5 V, the M950x0-R can operate with a supply voltage from 1.8 V to 5.5 V, and the M950x0-DF can operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of -40 ℃ /+85 ℃ The M950x0-DF offers an additional page, named the Identification Page (16 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
