M95040-DF Datasheet Spi Bus Eeprom

Manufacturer: STMicroelectronics

Overview: M950x0-W M950x0-R M950x0-DF Datasheet 4 Kbit, 2 Kbit and 1 Kbit serial SPI bus EEPROM with high-speed clock SO8N (150 mil width) TSSOP8 (169 mil width) UFDFPN8 (MC) DFN8 (2 x 3 mm) Product status link M95040-DF M95010-R.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

1 Description 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.
