24FC64-I/SM

Memory IC Overview

The Microchip Technology 24FC64-I/SM 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 for supply voltages between 2.5V and 5.5V, while operating at 400 kHz below 2.5V. The device operates within a voltage range of 1.7V to 5.5V and is housed in an 8-lead Small Outline J-Lead (SOIJ) package. It supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer
• Includes hardware write protection via the WP pin
• Features a 32-byte page write buffer for optimized writing
• Provides Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices utilizing I2C communication buses
• Low-voltage portable electronics powered by single supplies

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the SOIJ package type. Confirm the 'I' designation matches the required industrial temperature range specifications. Ensure the component meets RoHS compliance requirements for your specific manufacturing process. Cross-reference the datasheet revision to confirm electrical characteristics align with current design constraints.

Memory IC Selection Notes

Select this component when a 1 MHz bus speed is necessary compared to standard 400 kHz EEPROMs. Choose the SOIJ package for applications requiring specific footprint dimensions or lead configurations not available in MSOP or SOIC formats. Consider the 1.7V minimum operating voltage for compatibility with low-power system architectures.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit serial EEPROMs manufactured by Microchip Technology. The FC variant specifically denotes support for higher clock frequencies up to 1 MHz. The SM suffix identifies the physical packaging as an 8-lead Small Outline J-Lead component designed for surface mount technology applications.

Memory IC Replacement Considerations

Compatible substitutes include other 24FC64 variants such as 24FC64-I/MF or 24FC64-I/SN, provided the package difference is acceptable. The 24LC64 series offers similar functionality but is limited to a 400 kHz maximum clock frequency.
