The M95010/M95020/M95040 devices (M950x0) are electrically erasable programmable memories (EEPROMs) organized as 128/256/512 x 8 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 °C / +85 °C The M950x0-DF offers an additional page, named the identification page (16 bytes). The identification page can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode.

The M95020-A125 and M95020-A145 are 2-Kbit serial EEPROM Automotive grade devices operating up to 145°C. They are compliant with the very high level of reliability defined by the Automotive standard AEC-Q100 grade 0. The devices are accessed by a simple serial SPI compatible interface running up to 20 MHz. The memory array is based on advanced true EEPROM technology (Electrically Erasable PROgrammable Memory). The M95020-A125 and M95020-A145 are byte-alterable memories (256 × 8 bits) organized as 16 pages of 16 byte in which the data integrity is significantly improved with an embedded Error Correction Code logic. The M95020-A125 and M95020-A145 offer an additional Identification Page (16 byte) in which the ST device identification can be read. This page can also be used to store sensitive application parameters which can be later permanently locked in read-only mode.
