24AA01T-I/MC

Memory IC Overview

The Microchip Technology 24AA01T-I/MC is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire serial interface compatible with I²C protocols. It operates on a single supply voltage ranging from 1.7V to 5.5V, supporting clock frequencies up to 400 kHz at voltages of 2.5V or higher, and 100 kHz below 2.5V. The device includes an 8-byte page write buffer, hardware write-protect functionality via the WP pin, and Schmitt trigger inputs for noise suppression. It is qualified for industrial temperature ranges (-40°C to +85°C) and offers high endurance exceeding one million erase/write cycles with data retention greater than 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with I²C compatibility
• Includes hardware write-protect capability through the dedicated WP pin
• Features Schmitt trigger inputs and filter circuits for enhanced noise immunity
• Provides an 8-byte page write buffer to optimize data transfer efficiency

Memory IC Applications

• Low-power data acquisition systems requiring non-volatile storage
• Personal communications devices utilizing minimal power budgets
• Industrial control applications needing reliable parameter storage
• Embedded systems requiring hardware-level write protection

Memory IC Procurement Notes

Verify that the ordering suffix 'MC' corresponds to the specific 8-lead DFN package type required for your design. Confirm the 'I' designation matches the necessary industrial temperature range specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the datasheet revision to confirm electrical characteristics align with current system constraints.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM operating down to 1.7V is required. It is suitable for designs where space is limited due to the available compact package options. Choose this part if hardware write protection is essential for data integrity without software overhead. Consider the 400 kHz maximum clock speed for bus timing requirements in your application architecture.

Memory IC Part Context

This device belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24LC01B and 24FC01, which share similar functional architectures but differ in voltage ranges and maximum clock speeds. The 24AA01 variant specifically supports operation down to 1.7V, distinguishing it from parts requiring higher minimum supply voltages.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC01B and 24FC01, provided voltage and speed requirements are met. Verify package compatibility when replacing with other 8-lead options like SOIC or TSSOP. Ensure the replacement part supports the required industrial temperature grade.
