N24C64 Datasheet, PDF (1/11 Pages) ON Semiconductor – 64 Kb I2C CMOS Serial EEPROM

N24C64
64 Kb I²C CMOS Serial
EEPROM
Description
The N24C64 is a 64 Kb CMOS Serial EEPROM 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
N24C64 devices on the same bus.
