24FC64-I/MF

Memory IC Overview

The Microchip Technology 24FC64-I/MF is a 64-Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 1 MHz for VCC ≥ 2.5V and 400 kHz for VCC < 2.5V. The device operates on a single supply voltage ranging from 1.7V to 5.5V. It utilizes low-power CMOS technology, drawing a maximum active current of 3 mA and a standby current of 1 µA. The component supports page write operations with a 32-byte buffer and includes hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation at voltages of 2.5V or higher
• Includes Schmitt trigger inputs for enhanced noise suppression
• Features output slope control to eliminate ground bounce effects
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Low-voltage portable devices utilizing I2C communication buses

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple physical formats. Confirm the temperature grade corresponds to the intended operating environment. Ensure the voltage requirements align with the system's power supply rails before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface speed is necessary within the 24XX64 family. It is suitable for designs requiring operation down to 1.7V, distinguishing it from variants limited to higher minimum voltages. Consider the MSOP-8 package constraints regarding board space and thermal dissipation during the selection process.

Memory IC Part Context

This device belongs to the 24XX64 series of 64-Kbit serial EEPROMs manufactured by Microchip Technology. The series encompasses variants with different voltage ranges and clock speeds, such as the 24AA64 and 24LC64. The 'FC' designation specifically indicates support for the 1 MHz clock rate under appropriate voltage conditions.

Memory IC Replacement Considerations

The 24FC64T-I/MF serves as a tape-and-reel replacement for the tube-packaged 24FC64-I/MF. Other family members like the 24AA64 or 24LC64 may function electrically but differ in maximum clock frequency or minimum operating voltage specifications.
