24FC64F-I/MS

Memory IC Overview

The Microchip Technology 24FC64F-I/MS is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring a 2-Wire I2C compatible serial interface. It supports a maximum clock frequency of 1 MHz and operates on a single supply voltage ranging from 1.7V to 5.5V. The device utilizes low-power CMOS technology with a typical read current of 400 µA and standby current of 1 µA. It includes hardware write protection for the upper quarter of the array and offers data retention exceeding 200 years. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock frequency for efficient data transfer
• Includes hardware write protection for the upper 1/4 of the memory array
• Features Schmitt trigger inputs for improved noise suppression
• Allows cascading up to eight devices on the same bus via address pins

Memory IC Applications

• Personal communications systems requiring non-volatile storage
• Data acquisition applications needing low-power EEPROM
• Industrial control systems operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically MSOP for this part number. Confirm the temperature grade 'I' corresponds to the intended industrial operating range of -40°C to +85°C. Ensure the voltage supply meets the minimum 1.7V requirement for full functionality at higher clock speeds. Check RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface speed is required compared to standard 400 kHz alternatives. Choose the MSOP package for space-constrained surface-mount designs. Consider the hardware write-protect feature if specific memory sectors require permanent protection against accidental modification. Verify that the 1.7V minimum supply voltage aligns with the system power architecture.

Memory IC Part Context

This device belongs to the 24XX64F family of 64 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA64F and 24LC64F but distinguishes itself through its support for 1 MHz clock frequencies. The family utilizes a common 2-wire serial protocol, ensuring compatibility across different voltage and speed variants within the same product line.
