24AA01HT-I/OT

Memory IC Overview

The Microchip Technology 24AA01HT-I/OT is a 1 Kbit (128 x 8) serial EEPROM utilizing 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. The device features hardware write-protect capabilities for half the array, low standby current, and high ESD protection. It is housed in a compact 5-lead SC-70 package designed for surface mount applications.

Memory IC Feature Summary

• Hardware write-protect pin enables selective protection of the upper memory half
• Schmitt trigger inputs provide noise suppression on data and clock lines
• Output slope control minimizes ground bounce during switching
• Low-power CMOS technology ensures minimal active and standby currents

Memory IC Applications

• Consumer electronics requiring non-volatile data storage
• Industrial systems needing reliable parameter retention
• Portable devices constrained by low power budgets

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range aligns with system requirements, as the 'I' suffix denotes industrial specifications. Ensure compatibility with the host controller's I²C bus timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a small footprint is critical due to the 5-lead SC-70 packaging. It is suitable for designs requiring operation down to 1.7V. Consider the hardware write-protect feature if partial memory security is needed without software overhead.

Memory IC Part Context

This part belongs to the 24AA01H family of 1 Kbit serial EEPROMs. It shares functional similarities with other members like the 24AA01HT-I/SN but differs in physical package dimensions. The family supports standard I²C protocols and offers various package options including SOIC and TDFN.

Memory IC Replacement Considerations

Direct replacements include other 24AA01H variants such as 24AA01HT-I/SN or 24AA01HT-I/MNY, provided the package difference is accommodated by the PCB layout.
