CAV24C32 Datasheet, PDF (1/10 Pages) ON Semiconductor – CMOS Serial EEPROM

CAV24C32
32-Kb I²C CMOS Serial
EEPROM
Description
The CAV24C32 is a 32−Kb CMOS Serial EEPROM devices,
internally organized as 4096 words of 8 bits each.
It features a 32−byte page write buffer and supports the Standard
(100 kHz) and Fast (400 kHz) I²C protocol.
External address pins make it possible to address up to eight
CAV24C32 devices on the same bus.
