24LC64F-E/SN

Memory IC Overview

The Microchip Technology 24LC64F-E/SN is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring an I²C-compatible 2-wire 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, ensuring high endurance with over one million erase/write cycles and data retention exceeding 200 years. It is housed in an 8-lead SOIC package and certified for the Automotive temperature grade, functioning reliably from -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using three functional address pins.
• Includes hardware write protection for the upper quarter of the memory array.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides a 32-byte page write buffer for efficient data transfer.

Memory IC Applications

• Personal communications systems
• Data acquisition modules
• Advanced low-power embedded applications

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm compliance with RoHS standards and ensure the selected variant matches the intended operating voltage and environmental conditions for the target application design.

Memory IC Selection Notes

Select this component when automotive-grade reliability is required alongside standard I²C compatibility. Ensure the system design accommodates the 2.5V minimum supply voltage constraint. Verify that the physical layout supports the 8-SOIC footprint and allows for proper connection of the A0, A1, and A2 address pins.

Memory IC Part Context

This part belongs to the 24LC64F family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA64F and 24FC64F variants but is distinguished by its specific voltage requirements and automotive temperature rating. The 'E' suffix denotes the extended temperature range suitable for harsh environments.

Memory IC Replacement Considerations

Direct substitutes include other 24LC64F variants with different packages or temperature grades, such as 24LC64F-I/SN for industrial use. Cross-vendor equivalents require verification of pinout compatibility and electrical specifications.
