24LC64FT-E/MNY

Memory IC Overview

The Microchip Technology 24LC64FT-E/MNY is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, with maximum active read current of 400 µA and standby current of 1 µA. It includes hardware write protection for the upper quarter of the array and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability for the upper quarter of the memory array via the WP pin
• 32-byte page write buffer for efficient sequential data storage operations
• Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes
• Output slope control designed to eliminate ground bounce during switching

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems storing sensor parameters or logs
• Embedded applications needing configuration data preservation
• Industrial controllers utilizing I2C bus architecture

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'E' designation matches the required automotive temperature range of -40°C to +125°C. Ensure the MNY package type aligns with PCB layout constraints. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with current design requirements.

Memory IC Selection Notes

Select this component for designs requiring robust noise immunity in industrial environments due to Schmitt trigger inputs. The hardware write-protect feature suits applications needing secure storage for critical calibration data. Verify that the 400 kHz speed meets system timing requirements. Consider the 8-TDFN package size if space-constrained surface mount assembly is necessary.

Memory IC Part Context

This part belongs to the 24LC64F family of 64 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA64F and 24FC64F but differs in minimum operating voltage and maximum clock frequency specifications. The device is designed for advanced low-power applications and supports cascading up to eight units on a single bus using address pins A0, A1, and A2.

Memory IC Replacement Considerations

The 24LC64T-I/MNY serves as an industrial temperature grade alternative. The 24LC64F-E/MS provides the same electrical characteristics in an MSOP package.
