24LC64FT-I/OT

Memory IC Overview

The 24LC64FT-I/OT is a 64 Kbit Electrically Erasable PROM organized as 8K x 8 bits. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features a 2-wire serial interface compatible with I²C™ and utilizes a SOT-23 package. Key electrical parameters include a typical access time of 900 ns, standby current of 1 µA (max), and read current of 400 µA (max). It supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports up to eight devices on the same bus using functional address lines for expanded addressing.
• Includes hardware write protection that inhibits write operations for the upper quarter of the memory array.
• Features Schmitt trigger inputs to suppress noise and output slope control to eliminate ground bounce.

Memory IC Applications

• Personal communications systems requiring low-power non-volatile storage.
• Data acquisition applications utilizing advanced low-power designs.
• Industrial environments operating within specified temperature and voltage ranges.

Memory IC Procurement Notes

Verify the specific suffix 'I/OT' corresponds to the Industrial temperature grade (-40°C to +85°C) and the SOT-23-5 package configuration. Confirm that the 'F' designation indicates the inclusion of quarter-array write protection capabilities compared to standard variants. Ensure compatibility with the required I²C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for 64 Kbit EEPROM storage. The SOT-23 package is suitable for space-constrained designs where three physical address pins are not needed, relying instead on fixed logic levels for chip selection. Verify that the 400 kHz clock speed meets the system's data transfer requirements.

Memory IC Part Context

This part belongs to the 24AA64F/24LC64F/24FC64F family of serial EEPROMs manufactured by Microchip Technology. The 'LC' variant specifically denotes operation down to 2.5V, distinguishing it from the 1.7V capable 'AA' and 'FC' series members. The 'T' suffix typically indicates tape and reel packaging for automated assembly processes.

Memory IC Replacement Considerations

Direct replacements within the same package and specifications include other 24LC64F variants in SOT-23 packages, such as 24LC64T-I/OT. Cross-family substitutes like 24AA64F or 24FC64F require verification of voltage range and clock frequency compatibility.
