DEVICE 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 (400 kHz)
I
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.
