Product overview

Description

The M95M01 devices are electrically erasable programmable memories (EEPROMs) organized as 131072 x 8 bits, accessed through the SPI bus.

The M95M01-R can operate with a supply range from 1.8 V to 5.5 V, the M95M01-DF can operate with a supply range from 1.7 V up to 5.5 V. These devices are guaranteed over the -40 °C/+85 °C temperature range.

The M95M01-DF offers an additional page, named the identification page (256 bytes). The identification page can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode.

The SPI bus signals are C, D and Q. The device is selected when chip select (S) is driven low. Communications with the device can be interrupted when the HOLD is driven low.
