DEVICE DESCRIPTION
The CAT24C03/CAT24C05 is a 2-kb/4-kb 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 (100kHz) as well as Fast
(400kHz) I
2
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.
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.
