24AA024HT-I/SN

Memory IC Overview

The Microchip Technology 24AA024HT-I/SN 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 includes Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and hardware write protection for half the array via the WP pin. It supports page writes of up to 16 bytes and offers high endurance with over 1 million erase/write cycles.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Schmitt trigger inputs and output slope control for enhanced noise immunity
• Self-timed write cycle with automatic erase-before-write capability
• Supports up to eight devices on the same bus using configurable address lines

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in sensor modules
• Parameter storage in low-power IoT devices

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging as specified by the manufacturer. Confirm the 'I' suffix indicates the Industrial temperature grade (-40°C to +85°C). Ensure compatibility with the target system's I²C voltage levels and pull-up resistor requirements before integration.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution is required with robust noise immunity and hardware-level write protection. It is suitable for applications needing operation down to 1.7V and support for multiple devices on a single I²C bus. Verify package availability matches the PCB footprint constraints.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2-Kbit Serial Electrically Erasable PROMs. It shares functional similarities with the 24LC024H but differs in minimum operating voltage and maximum clock frequency specifications. The family utilizes a standard 8-pin package configuration with dedicated pins for chip select and write protection.

Memory IC Replacement Considerations

Direct substitutes include the 24LC024H series, though voltage and speed specifications differ. Cross-reference with other 24AA024 variants ensuring identical package type and temperature rating.
