24AA01T-I/MNY

Memory IC Overview

The Microchip Technology 24AA01T-I/MNY is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum active current of 1 mA and standby current of 1 µA. It includes an 8-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead TDFN package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transmission over a 2-wire serial bus with I2C compatibility
• Includes hardware write-protect functionality controlled by the WP pin to inhibit memory writes
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce
• Provides acknowledge polling capability to maximize bus throughput during internal write cycles

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications operating within specified temperature ranges
• Devices utilizing I2C communication protocols for configuration or calibration data retention

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific voltage range requirements align with the 1.7V to 5.5V specification. Ensure the design accounts for the 400 kHz maximum clock frequency limitation at lower voltages. Check for RoHS compliance status if required by project specifications.

Memory IC Selection Notes

Select this component when a small capacity EEPROM with I2C interface is needed. Consider the 1.7V minimum operating voltage for battery-powered designs. Evaluate the 8-byte page write buffer size against application write patterns. Verify that the TDFN package fits the available PCB space constraints.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC01B and 24FC01 devices but differs in voltage ranges and clock speeds. The 'I' designation indicates an industrial temperature rating, while 'MNY' specifies the 8-lead TDFN package configuration.

Memory IC Replacement Considerations

Direct substitutes include other parts within the 24XX01 family such as the 24LC01B or 24FC01, provided voltage and speed requirements are met. Cross-reference package dimensions and pinouts before substitution.
