Description

The NV24C64MUW is a EEPROM Serial 64−Kb I2C Automotive

Grade 1 device, organized internally as 256 pages of 32 bytes each.

This device supports the Standard (100 kHz), Fast (400 kHz) and

Fast−Plus (1 MHz) I2C protocol.

Data is written by providing a starting address, then loading 1 to 32

contiguous bytes into a Page Write Buffer, and then writing all data to

non−volatile memory in one internal write cycle. Data is read by

providing a starting address and then shifting out data serially while

automatically incrementing the internal address count.

External address pins make it possible to address up to eight

NV24C64MUW devices on the same bus.
