2-Kb, 4-Kb, 8-Kb and 16-Kb
I2C CMOS Serial EEPROM
Description
The CAV24C02/04/08/16 are 2−Kb, 4−Kb, 8−Kb and 16−Kb
respectively CMOS Serial EEPROM devices organized internally as
8/16/32/64 and 128 pages respectively of 16 bytes each. All devices

support both the Standard (100 kHz) as well as Fast (400 kHz) I C
protocol.
Data is written by providing a starting address, then loading 1 to 16
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
CAV24C02, four CAV24C04, two CAV24C08 and one CAV24C16
device on the same bus.
