CAT24C164
FEATURES
16-Kb CMOS Serial EEPROM, Cascadable
DEVICE DESCRIPTION
The CAT24C164 is a 16-Kb CMOS cascadable Serial
EEPROM device organized internally as 128 pages of
16 bytes each, for a total of 2048x8 bits. The device
supports both the Standard (100 kHz) as well as Fast
(400 kHz) 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.
External address pins make it possible to address
up to eight CAT24C164 devices on the same bus.
