24FC04H-E/ST

Memory IC Overview

The Microchip Technology 24FC04H-E/ST is a 4-Kbit (512 x 8) I²C serial EEPROM housed in an 8-lead TSSOP package. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device features hardware write protection for the upper half of the memory array, low standby current consumption, and Schmitt trigger inputs for noise suppression. It is qualified for extended industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock compatibility up to 1 MHz
• Includes hardware write-protection mechanism for the upper half of the memory array
• Features Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage in consumer electronics operating at low voltages
• Parameter retention in automotive systems meeting AEC-Q100 standards

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) and 'ST' indicates the TSSOP package. Confirm the specific voltage requirements align with the 1.7V to 5.5V operational range. Ensure the design accounts for the hardware write-protect pin functionality if data security is required.

Memory IC Selection Notes

Select this component when high-speed I²C access is necessary compared to standard 400 kHz devices. It is suitable for applications requiring operation down to 1.7V where other variants may require higher minimum voltages. Consider the TSSOP package constraints for surface-mount assembly processes.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit serial EEPROMs. It shares architectural similarities with the 24AA04H and 24LC04BH but offers distinct performance characteristics regarding speed and voltage tolerance. The E suffix denotes the extended temperature grade, differentiating it from the standard industrial grade.

Memory IC Replacement Considerations

Direct substitutes include the 24FC04H-I/ST for industrial temperature range or the 24LC04BH-E/ST if the 2.5V minimum voltage constraint is acceptable. Verify pinout compatibility and electrical specifications before swapping.
