2-Kb and 4-Kb I2C Serial
EEPROM with Partial Array
Write Protection
Description
The CAT24C03/05 is a 2Kb/4Kb CMOS Serial EEPROM device
organized internally as 16/32 pages of 16 bytes each, for a total of
256x8/512x8 bits. These devices support both 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
nonvolatile 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.
Write operations can be inhibited for upper half of memory by
taking the WP pin High.
External address pins make it possible to address up to eight
CAT24C03 or four CAT24C05 devices on the same bus.
