CAT24M01WI-GT3 Programmable IC Chips 1 Mb I2C CMOS Serial EEPROM

CAT24M01

1 Mb I²C CMOS Serial EEPROM

Description

The CAT24M01 is a 1024 kb Serial CMOS EEPROM, internally organized as 131,072 words of 8 bits each.

It features a 256−byte page write buffer and supports the Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I²C protocol.

Write operations can be inhibited by taking the WP pin High (this protects the entire memory).

External address pins make it possible to address up to four CAT24M01 devices on the same bus.

ABSOLUTE MAXIMUM RATINGS

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

1. The DC input voltage on any pin should not be lower than −0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may undershoot to no less than −1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.
