24FC64-I/ST

Memory IC Overview

The Microchip Technology 24FC64-I/ST 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 levels between 2.5V and 5.5V, and 400 kHz for VCC levels between 1.7V and 2.5V. The device operates on a single supply voltage ranging from 1.7V to 5.5V. It supports page write operations with a 32-byte buffer and includes hardware write protection via the WP pin. The component is housed in an 8-lead TDFN package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication at standard operating voltages
• Includes a 32-byte page write buffer for efficient data transfer
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Low-power consumer electronics utilizing I2C buses

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm that the voltage supply in the target application aligns with the specified operational limits for the desired clock frequency. Ensure compatibility with the host controller's I2C bus timing requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 64-Kbit EEPROM capacity is required alongside high-speed 1 MHz I2C performance. It is suitable for designs operating within the 1.7V to 5.5V range where industrial temperature stability is necessary. Consider alternative packages if space constraints differ from the TDFN form factor.

Memory IC Part Context

This part belongs to the 24XX64 family of serial EEPROMs, which also includes the 24AA64 and 24LC64 variants. These devices share similar architectural features but differ in maximum clock frequencies and minimum operating voltages. The 24FC64 specifically offers the highest speed within this group.

Memory IC Replacement Considerations

Compatible substitutes include other 24FC64 variants with different package options such as MSOP or SOIC, provided the electrical specifications remain identical.
