24FC04HT-E/MUY

Memory IC Overview

The Microchip Technology 24FC04HT-E/MUY is a 4-Kbit (512 x 8) I2C serial EEPROM in an 8-lead UDFN package. It operates on a single supply from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device features hardware write protection for the upper half-array (addresses 100h-1FFh), Schmitt trigger inputs, and output slope control. It supports page writes up to 16 bytes with a maximum cycle time of 5 ms.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Low-power CMOS technology with standby current as low as 1 µA
• I2C compatible two-wire serial interface supporting up to 1 MHz clock frequency
• Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial environments requiring extended temperature operation
• 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 'E' suffix confirms the Extended temperature range (-40°C to +125°C) and the 'HT' indicates tape-and-reel packaging. Confirm the 'MUY' suffix corresponds to the 8-lead UDFN package type. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Memory IC Selection Notes

Select this part when high-speed 1 MHz I2C communication is required alongside low-voltage operation down to 1.7V. The Extended temperature grade is necessary for applications exceeding standard industrial limits. The UDFN package is suitable for space-constrained surface-mount designs.

Memory IC Part Context

This component belongs to the 24XX04H family, which includes variants like the 24AA04H and 24LC04BH. Unlike the 24LC04BH which requires a minimum of 2.5V, the 24FC04H variant supports operation down to 1.7V. It shares the same 4-Kbit capacity and half-array write protection architecture as its siblings.

Memory IC Replacement Considerations

Public confirmed substitutes include the 24FC04T-I/MUY and 24FC04HT-I/MUY. These parts share identical electrical specifications and pinouts but may differ in temperature grades or packaging formats.
