24FC64FT-I/SN

Memory IC Overview

The Microchip Technology 24FC64FT-I/SN is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device supports page writes up to 32 bytes and includes hardware write protection for the upper quarter of the array. It is housed in an 8-lead SOIC package, rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation within specified voltage ranges
• Includes hardware write protection for the upper quarter of the memory array
• Features a 32-byte page write buffer for efficient data transfer
• Provides Schmitt trigger inputs for improved noise suppression

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape and reel packaging rather than tube packaging when sourcing this specific variant. Confirm the 'I' temperature grade matches the required operational range of -40°C to +85°C. Ensure the 'SN' suffix aligns with the required 8-lead SOIC physical footprint for PCB layout compatibility.

Memory IC Selection Notes

Select this component over standard variants if the application requires 1 MHz clock speeds, as other family members may be limited to 400 kHz. Choose the tape and reel format for automated surface mount assembly processes. Consider the hardware write protect feature if security against accidental modification of critical configuration data is required.

Memory IC Part Context

This part belongs to the 24XX64F series of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA64F and 24LC64F but offers higher speed performance. The series utilizes CMOS technology for low power consumption and is designed for advanced embedded memory applications.
