24FC04HT-I/OT

Memory IC Overview

The Microchip Technology 24FC04HT-I/OT is a 4-Kbit (512 x 8) I²C Serial EEPROM housed in a 5-lead SOT-23 package. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device features hardware write protection for the upper half of the memory array, low standby current, and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Low-power CMOS technology enabling operation down to 1.7V
• I²C compatible two-wire serial interface with Schmitt trigger inputs

Memory IC Applications

• Data logging in battery-powered devices
• Configuration storage in embedded systems
• Parameter retention in industrial controllers

Memory IC Procurement Notes

Verify the specific suffix 'OT' corresponds to the 5-lead SOT-23 package and tape-and-reel delivery format as defined by Microchip Technology. Confirm that the 'I' designation matches the required industrial temperature range (-40°C to +85°C). Ensure the ordering information aligns with the latest datasheet DS20002119C to avoid discrepancies in package type or electrical characteristics.

Memory IC Selection Notes

Select this component when a compact SOT-23 footprint is required alongside high-speed 1 MHz I²C communication. It is suitable for applications needing hardware write protection for critical data segments without software overhead. Consider the 1.7V minimum operating voltage for compatibility with low-voltage logic systems.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit I²C Serial EEPROMs. It shares architectural similarities with the 24AA04H and 24LC04BH but offers higher clock speed compatibility up to 1 MHz compared to the 400 kHz limit of other variants in the series.

Memory IC Replacement Considerations

Direct replacements include other 24FC04H variants in different packages such as 24FC04T-I/SN (SOIC) or 24FC04HT-I/Q4B (UDFN), provided the pinout and electrical specifications remain compatible.
