24FC64T-I/MC

Memory IC Overview

The Microchip Technology 24FC64T-I/MC is a 64-Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a two-wire serial interface compatible with I2C protocols and supports a maximum clock frequency of 1 MHz at supply voltages between 2.5V and 5.5V, while maintaining compatibility down to 100 kHz for lower voltage operation. The device operates within a supply range of 1.7V to 5.5V and includes a 32-byte page write buffer with a maximum write cycle time of 5 ms. It utilizes an 8-lead DFN package (2x3 mm) and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer in standard voltage environments
• Includes a 32-byte page write buffer to optimize sequential data writing operations
• Features hardware write protection via the WP pin to secure memory arrays against unauthorized modifications
• Provides Schmitt trigger inputs on SDA and SCL lines to enhance noise suppression and signal integrity

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing compact surface-mount memory solutions
• Automotive applications supporting extended temperature ranges

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration for automated assembly processes. Confirm the industrial temperature grade designation aligns with environmental operating constraints. Ensure the voltage supply levels in the target circuit support the specified 1 MHz clock frequency requirements for optimal performance.

Memory IC Selection Notes

Select this component when high-speed serial communication is necessary alongside low-power consumption characteristics. The device is suitable for designs requiring hardware-level write protection and robust noise immunity through Schmitt trigger inputs. Consider the 8-DFN package dimensions for space-constrained printed circuit board layouts where surface mount technology is preferred over through-hole alternatives.

Memory IC Part Context

This part belongs to the 24XX64 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA64 and 24LC64 variants but distinguishes itself through enhanced clock speed capabilities. The family offers various package options including MSOP, SOIC, and TDFN configurations to accommodate diverse design requirements.

Memory IC Replacement Considerations

The 24FC64T-I/MS serves as a direct package alternative offering identical electrical specifications in an MSOP-8 footprint.
