CAT24C02, CAT24C04,
CAT24C08, CAT24C16
EEPROM Serial
2/4/8/16 Kb I2C
Description
The CAT24C02/04/08/16 are 2−Kb, 4−Kb, 8−Kb and 16−Kb
respectively I2C Serial EEPROM devices organized internally as
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) I2C
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
CAT24C02, four CAT24C04, two CAT24C08 and one CAT24C16
device on the same bus.
