24LC64F-I/P

Memory IC Overview

The Microchip Technology 24LC64F-I/P is a 64 Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a 2-wire serial interface compatible with I²C™ and operates on a single supply voltage ranging from 2.5V to 5.5V. The device supports clock frequencies up to 400 kHz and includes Schmitt trigger inputs for noise suppression. It offers hardware write protection for the upper quarter of the array, a 32-byte page write buffer, and over 1 million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with I²C compatibility
• Includes hardware write-protect capability for the upper quarter of the memory array
• Features a 32-byte page write buffer for efficient data transfer
• Provides high ESD protection exceeding 4,000V on all pins

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Industrial control applications
• Power management circuits

Memory IC Procurement Notes

Verify that the specific part number corresponds to the Industrial temperature grade (-40°C to +85°C) and the PDIP package style. Confirm the operating voltage range requirements align with the specified 2.5V to 5.5V limits. Ensure the design accounts for the I²C pull-up resistor requirements on the SDA and SCL lines. Check for any specific factory programming needs or RoHS compliance documentation if required by the project specifications.

Memory IC Selection Notes

Select this component when a low-power, non-volatile memory solution with I²C interface is required. It is suitable for applications needing hardware write protection for critical data segments. Consider the PDIP package for through-hole mounting requirements. Evaluate the 400 kHz maximum clock speed against system bus timing constraints. Ensure the application voltage stays within the 2.5V to 5.5V operational window.

Memory IC Part Context

This device belongs to the 24XX64F family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA64F and 24FC64F variants, differing primarily in minimum operating voltage and maximum clock frequency specifications. The 'I' suffix denotes the industrial temperature range, while '/P' indicates the 8-lead PDIP package type.

Memory IC Replacement Considerations

Compatible substitutes include the 24AA64F-I/P and 24FC64F-I/P from the same manufacturer family. Verify voltage compatibility, as the 24AA64F supports lower voltages down to 1.7V. Ensure the replacement maintains the same package footprint and pinout configuration.
