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.
