24FC04HT-I/ST

Memory IC Overview

The Microchip Technology 24FC04HT-I/ST is a 4-Kbit (512 x 8) serial EEPROM featuring an I2C interface. It supports clock frequencies up to 1 MHz and operates on a single supply voltage ranging from 1.7V to 5.5V. The device includes hardware write-protect functionality for half the array, utilizes an 8-TSSOP package, and functions within industrial temperature ranges of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock compatibility up to 1 MHz
• Provides hardware write protection for the upper half of the memory array via the WP pin
• Features low-power CMOS technology with standby current as low as 1 µA
• Includes Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific tape-and-reel packaging variant required for automated assembly processes. Confirm the 'I' designation matches the intended industrial temperature range specifications for the application environment.

Memory IC Selection Notes

Select this component when high-speed data transfer rates are necessary compared to standard 400 kHz devices. Ensure the design accommodates the 1.7V minimum operating voltage if powering from lower voltage rails. Verify that the half-array write-protect feature aligns with the security requirements for the stored data.

Memory IC Part Context

This part belongs to the 24XX04H family of serial EEPROMs, which shares architectural similarities with the 24AA04H and 24LC04BH. The primary distinction lies in the maximum clock frequency capability, where the 24FC04H variant supports 1 MHz operation compared to the 400 kHz limit of other family members.

Memory IC Replacement Considerations

Direct substitutes include the 24AA04H-I/ST and 24LC04BH-I/ST. Note that these alternatives operate at a maximum clock frequency of 400 kHz, which may impact system throughput if high-speed communication is required.
