DEVICE DESCRIPTION

The CAT24C64 is a 64-Kb CMOS Serial EEPROM

devices, internally organized as 128 pages of 64 bytes

each.

It features a 32-byte page write buffer and supports

both the Standard (100 kHz) as well as Fast (400 kHz)

External address pins make it possible to address up to

eight CAT24C64 devices on the same bus.
