Description

M95160 M95160-W M95160-R M95160-DF

The M95160 devices are Electrically Erasable PROgrammable Memories (EEPROMs)

organized as 2048 x 8 bits, accessed through the SPI bus.

The M95160-W can operate with a supply voltage from 2.5 V to 5.5 V, the M95160-R can

operate with a supply voltage from 1.8 V to 5.5 V, and the M95160-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 M95160-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.
