24AA024HT-I/MNY

Memory IC Overview

The Microchip Technology 24AA024HT-I/MNY is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz in the Industrial temperature range (-40°C to +85°C). The device utilizes low-power CMOS technology, drawing a maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for half the array via the WP pin, supports page writes up to 16 bytes, and offers high endurance exceeding one million erase/write cycles.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array through the dedicated WP pin.
• Integrated Schmitt trigger inputs and noise filters provide enhanced signal integrity and suppression of bus spikes.
• Supports acknowledge polling to allow the master controller to determine when internal write cycles are complete.
• Low-voltage operation down to 1.7V ensures compatibility with diverse power supply architectures.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings
• Configuration parameter storage in industrial control modules
• Calibration data retention for electronic measurement instruments

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range aligns with system requirements, as the 'AA' variant supports lower voltages than the 'LC' series. Ensure the design accounts for the TDFN package thermal characteristics and handling procedures during assembly.

Memory IC Selection Notes

Select this component for applications requiring robust noise immunity and flexible addressing on shared buses. The inclusion of hardware write protection makes it suitable for critical data preservation. Verify that the 400 kHz speed meets timing constraints and that the 16-byte page buffer size fits the application's write efficiency needs.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other devices in the series but is distinguished by its specific voltage operating range and package configuration. The 'HT' suffix indicates a tape and reel packaging format optimized for automated surface-mount assembly processes.

Memory IC Replacement Considerations

Direct replacements include the 24AA024T-I/MNY or 24LC024HT-I/MNY, provided the voltage specifications match the application design. Cross-referencing datasheets is necessary to confirm identical pinouts and electrical characteristics before substitution.
