24AA024T-I/MC

Memory IC Overview

The Microchip Technology 24AA024T-I/MC is a 2 Kbit (256 x 8-bit) Serial Electrically Erasable PROM. It operates on a single supply from 1.7V to 5.5V and features a 2-wire I²C compatible serial interface. The device supports clock frequencies of 100 kHz and 400 kHz, with a maximum page write time of 5 ms. It includes hardware write protection via the WP pin, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. The component is rated for industrial temperature ranges (-40°C to +85°C) and offers high endurance and data retention specifications.

Memory IC Feature Summary

• Hardware write-protect capability enabled by tying the WP pin to VCC
• Supports cascading up to eight devices on a single bus using address pins A0-A2
• Includes output slope control to eliminate ground bounce during operation
• Features Schmitt trigger inputs for enhanced noise suppression on SDA and SCL lines

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in sensor interfaces
• Parameter storage in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the '/MC' suffix corresponds to the specific package type required, as this part number family utilizes multiple package options including SOIC, TSSOP, DFN, and MSOP. Ensure the application voltage remains within the 1.7V to 5.5V range to maintain specified electrical characteristics.

Memory IC Selection Notes

Select this component when hardware write protection is required, distinguishing it from the 24LC024 variant which lacks the WP pin. Choose this model over the 24AA025 if the additional capacity or different addressing scheme of the 25-series is not needed. Ensure the design accommodates the 16-byte page write buffer limitations to prevent data overwrite across page boundaries.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. It shares the same memory organization and interface protocol as its siblings but differs in voltage ranges and write-protection features. The 24AA series generally supports lower voltage operation down to 1.7V compared to the 24LC series.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 24AA024T-E/MC, 24LC024T-I/MC.
