DEVICE DESCRIPTION

The CAT24C32 is a 32-Kb CMOS Serial EEPROM

devices, internally organized as 128 pages of 32 bytes

each.

It features a 32-byte page write buffer and supports

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

I2C protocol.

External address pins make it possible to address up to

eight CAT24C32 devices on the same bus.

For Ordering Information details, see page 15.
