ON Semiconductor CAT24C01 Manual

CAT24C01, CAT24C02,
CAT24C04, CAT24C08,
CAT24C16
1-Kb, 2-Kb, 4-Kb, 8-Kb and
2
16-Kb I C CMOS Serial
EEPROM
Description
The CAT24C01/02/04/08/16 are 1−Kb, 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
2
(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
CAT24C01 or CAT24C02, four CAT24C04, two CAT24C08 and one
CAT24C16 device on the same bus.
