24FC04HT-I/MUY

Memory IC Overview

The Microchip Technology 24FC04HT-I/MUY is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C serial interface. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device includes hardware write-protect functionality for the upper half of the memory array (addresses 100h-1FFh). It is housed in an 8-lead UDFN package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power CMOS technology with standby current as low as 1 µA
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Supports page write operations with a 16-byte buffer

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Consumer electronics utilizing I2C communication protocols
• Embedded controllers needing configuration parameter retention
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify the specific suffix 'HT' indicates tape and reel packaging when ordering. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the system design accommodates the 8-lead UDFN footprint dimensions. Check for RoHS compliance status if restricted substances are a constraint. Validate that the host controller supports the 1 MHz clock speed for optimal performance.

Memory IC Selection Notes

Select this component over standard variants when half-array write protection is required to secure critical data segments. Choose the UDFN package for applications demanding compact surface-mount solutions. Opt for this high-speed 1 MHz variant if faster bus throughput is necessary compared to 400 kHz devices. Consider the low operating voltage range for battery-powered or energy-efficient designs.

Memory IC Part Context

This part belongs to the 24XX04H family, which integrates half-array write protection into the standard 4-Kbit EEPROM architecture. The 24FC04H series specifically offers higher clock speeds than the 24AA04H or 24LC04BH counterparts. The 'HT' suffix denotes high-volume tape and reel packaging suitable for automated assembly processes.

Memory IC Replacement Considerations

Direct substitutes include other 24FC04H variants with different packages such as PDIP or MSOP, provided the pinout remains compatible. Cross-brand replacements like AT24C04 may require level shifting or voltage adjustments due to differing electrical specifications.
