24FC04HT-I/SN

Memory IC Overview

The Microchip Technology 24FC04HT-I/SN is a 4-Kbit (512 x 8) I2C Serial EEPROM housed in an 8-UDFN package. It operates within a voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device features hardware write protection for the upper half-array (addresses 100h-1FFh), a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. It provides over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection mechanism inhibits write operations to the upper half of the memory array when the WP pin is tied high.
• Integrated 16-byte page write buffer allows efficient sequential data storage by reducing internal write cycle frequency.
• Schmitt trigger inputs with spike suppression filters ensure reliable data transmission on noisy serial bus environments.

Memory IC Applications

• Non-volatile data logging in industrial control systems
• Configuration storage for embedded microcontroller applications
• Parameter retention in low-power consumer electronics

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the UDFN package type and Industrial temperature grade. Confirm the presence of the 'H' designation indicating half-array write protection functionality. Ensure compatibility with the target system's I2C bus voltage levels and timing requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact surface-mount footprint is required alongside high-speed 1 MHz I2C communication capabilities. The half-array write protection feature makes it suitable for applications requiring partial memory security without software overhead. Consider the low standby current for battery-operated designs needing extended operational life.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit I2C Serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA04H and 24LC04BH but offers distinct performance characteristics regarding clock speed and operating voltage ranges. The family utilizes a standardized two-wire serial interface protocol for data transfer.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24FC04H series such as 24FC04T-I/SN or 24FC04T-I/OT, provided the package type matches the design constraints. Cross-family replacements like 24LC04BHT-I/SN are possible but require verification of voltage and speed limitations.
