Description
The CAT24C01/02/04/08/16 are 1ïKb, 2ïKb, 4ïKb, 8ïKb and
16ïKb respectively CMOS Serial EEPROM devices organized
internally as 8/16/32/64 and 128 pages respectively of 16 bytes each.
All devices support both the Standard (100 kHz) as well as Fast
(400 kHz) I2 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
nonïvolatile 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
CAT24C01 or CA T24C02, four CA T24C04, two CAT24C08 and one
CAT24C16 device on the same bus.
Features Supports Standard and Fast I2 C Protocol 1.7 V to 5.5 V Supply Voltage Range 16ïByte Page Write Buffer Hardware Write Protection for Entire Memory Schmitt Triggers and Noise Suppression Filters on I2 C Bus Inputs
