EEPROM
Description
The CAT24C32 is a 32ïKb CMOS Serial EEPROM devices,
internally organized as 4096 words of 8 bits each.
It features a 32ïbyte page write buffer and supports the Standard
(100 kHz), Fast (400 kHz) and FastïPlus (1 MHz) I2 C protocol.
External address pins make it possible to address up to eight
CAT24C32 devices on the same bus.
Features Supports Standard, Fast and FastïPlus I2 C Protocol 1.7 V to 5.5 V Supply V oltage Range 32ïByte Page Write Buffer Hardware Write Protection for Entire Memory Schmitt Triggers and Noise Suppression Filters on I2 C Bus Inputs
