24AA08T-I/MC

Memory IC Overview

The 24AA08T-I/MC is an 8-Kbit (1024 x 8) serial EEPROM utilizing a two-wire I²C compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at voltages above 2.5V, and 100 kHz below 2.5V. The device features a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It supports industrial temperature operation from -40°C to +85°C and offers high endurance exceeding one million erase/write cycles.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol
• Includes a 16-byte page write buffer to optimize write throughput
• Provides hardware-based write protection through the dedicated WP pin
• Integrates Schmitt triggers and filter circuits to suppress bus noise

Memory IC Applications

• Data storage in battery-powered portable devices
• Configuration parameter retention in embedded systems
• Calibration data logging in industrial instrumentation
• Device identification and tracking in automotive electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'MC' corresponds to the Micro Lead Frame package type as specified in the datasheet. Confirm the 'I' suffix indicates the Industrial temperature grade (-40°C to +85°C). Ensure the 'T' suffix matches the required tape and reel packaging format for automated assembly processes.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.7V is required, distinguishing it from the 2.5V minimum 24LC08B variant. Choose this part over the 24FC08 if a maximum clock speed of 400 kHz is sufficient, as the 24FC08 supports 1 MHz. Consider the 16-byte page buffer size for applications requiring frequent small data updates.

Memory IC Part Context

This device belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24LC08B and 24FC08, which share similar memory architectures but differ in operating voltage ranges and maximum clock frequencies. The 24AA08 specifically targets applications requiring wide voltage compatibility and low power consumption.

Memory IC Replacement Considerations

The 24LC08B serves as a functional substitute provided the system supply voltage remains at or above 2.5V. The 24FC08 can replace this unit where higher clock speeds up to 1 MHz are beneficial. Verify that any replacement maintains the same 8-pin package configuration and I²C addressing scheme.
