24LC64T-I/MC

Memory IC Overview

The Microchip Technology 24LC64T-I/MC is a 64-Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It operates on a single supply voltage ranging from 2.5V to 5.5V and features a two-wire serial interface compatible with I2C protocols. The device supports maximum clock frequencies of 100 kHz at voltages below 2.5V and 400 kHz between 2.5V and 5.5V. It utilizes a DFN-8 package, offers a maximum access time of 900 ns, and maintains data retention for over 200 years.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using three hardware address pins.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a 32-byte page write buffer for efficient data transfer operations.
• Provides hardware write protection via the WP pin to secure the entire memory array.

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• I2C bus networks expanding address space through multiple units

Memory IC Procurement Notes

Verify that the ordering suffix 'MC' corresponds specifically to the DFN-8 package type required for your design. Confirm the industrial temperature grade 'I' meets your operational range of -40°C to +85°C. Ensure the voltage supply aligns with the 2.5V minimum requirement, as this variant does not support operation down to 1.7V like other family members.

Memory IC Selection Notes

Select this component when a 64-Kbit capacity is needed with I2C compatibility and robust noise immunity. It is suitable for applications where hardware write protection and high endurance are critical. Consider alternative packages if surface mount constraints differ or if lower voltage operation below 2.5V is required.

Memory IC Part Context

This part belongs to the 24LC64 series within the broader 24AA64/24FC64/24LC64 family. While sharing core architecture, the LC variant is distinct due to its specific 2.5V minimum operating voltage compared to the AA and FC versions which support 1.7V. The T suffix indicates tape and reel packaging.

Memory IC Replacement Considerations

The 24LC64-I/MC is a direct functional substitute for the 24LC64T-I/MC, differing only in bulk packaging rather than electrical characteristics. Other family members like 24AA64 or 24FC64 require voltage level adjustments due to different operating ranges.
