24FC64-I/MS

Memory IC Overview

The Microchip Technology 24FC64-I/MS 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, with a maximum active current of 3 mA and standby current of 1 µA. It utilizes an 8-lead MSOP package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation at voltages above 2.5V
• Includes hardware write protection via the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging in industrial systems
• Configuration storage for microcontrollers
• Parameter retention in low-voltage embedded devices

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature range. Confirm RoHS compliance status and ensure the datasheet version matches the required specifications for the target application environment.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface is required for faster data throughput compared to standard 400 kHz EEPROMs. Ensure the system power supply remains stable above 1.7V to support full functionality across the specified operating conditions.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit serial EEPROMs. It shares architectural similarities with the 24AA64 and 24LC64 but offers enhanced clock speed capabilities. The 'I' designation indicates the Industrial temperature grade, distinguishing it from Extended temperature variants.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA64-I/MS and 24LC64-I/MS. Note that these alternatives operate at a maximum clock frequency of 400 kHz, which may impact system performance if high-speed communication is critical.
