N24C32
32 Kb I2C CMOS Serial
EEPROM
Description
The N24C32 is a 32 Kb CMOS Serial EEPROM device, organized
internally as 128 pages of 32 bytes each. This device supports the
Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I C

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
N24C32 devices on the same bus.
