Description
The CAT24C01/02/04/08/16 are 1Kb, 2Kb, 4Kb, 8Kb and
16Kb respectively CMOS Serial EEPROM devices organized
TDFN8*

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
nonvolatile memory in one internal write cycle. Data is read by
