24AA01HT-I/MNY

Memory IC Overview

The Microchip Technology 24AA01HT-I/MNY is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I²C 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 read current of 1 mA and standby current of 1 μA. It supports page writes of up to 8 bytes with a typical write cycle time of 3 ms. The component includes hardware write-protect functionality for half the array and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection via the WP pin
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Supports standard and fast-mode I²C bus protocols with acknowledge polling
• High endurance with over one million erase/write cycles

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications operating within -40°C to +85°C temperature ranges
• Devices utilizing I²C communication for configuration or calibration data retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage supply range aligns with the 1.7V minimum requirement for the 'I' industrial grade variant. Ensure compatibility with the TDFN-8 surface mount package dimensions during PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for the application's memory needs. Choose this part for designs requiring operation down to 1.7V, as other variants may require higher voltages. Consider the TDFN-8 package for space-constrained surface-mount layouts. Verify that the 400 kHz clock speed meets the system's bus timing requirements.

Memory IC Part Context

This device belongs to the 24AA01H family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC01BH but differs in its lower minimum operating voltage of 1.7V compared to the 2.5V minimum of the LC series. The HT suffix indicates a specific tape and reel packaging format suitable for automated assembly processes.

Memory IC Replacement Considerations

The 24LC01BH serves as a functional alternative, though it requires a minimum supply voltage of 2.5V rather than 1.7V. Other members of the 24XX01 family offer different package options such as SOIC or TSSOP. Substitution should be verified against the specific voltage and package constraints of the target design.
