  • The M95640 devices are Electrically Erasable PROgrammable Memories (EEPROMs) organized as 8192 x 8 bits, accessed through the SPI bus.

    The M95640-W can operate with a supply voltage from 2.5 V to 5.5 V, the M95640-R can operate with a supply voltage from 1.8 V to 5.5 V and the M95640-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 M95640-D offers an additional page, named the Identification Page (32 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
