CAT24C164
16 kb CMOS Serial
EEPROM, Cascadable
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
2048 x 8 bits. The device supports both the 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
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.
