24FC04HT-E/SN

Memory IC Overview

The Microchip Technology 24FC04HT-E/SN is a 4-Kbit (512 x 8) serial EEPROM featuring an I2C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device includes hardware write protection for the upper half of the memory array (addresses 100h-1FFh). It is housed in an 8-lead SOIC package and rated for extended industrial temperatures from -40°C to +125°C.

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 3 µA at extended temperatures
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Data logging in industrial environments requiring high 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' confirms the extended temperature range (-40°C to +125°C) and 'SN' specifies the 8-lead SOIC package. Confirm the 'T' indicates tape-and-reel packaging if required by automated assembly processes. Ensure the specific revision matches the datasheet DS20002119C.

Memory IC Selection Notes

Select this component when an I2C EEPROM requires operation down to 1.7V and needs hardware-based protection for critical data segments. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Verify that the 1 MHz clock speed meets system timing requirements.

Memory IC Part Context

This part belongs to the 24XX04H family, which shares architectural similarities with the 24AA04H and 24LC04BH. Unlike the 24LC04BH which starts at 2.5V, the 24FC04H variant supports lower voltage operation starting at 1.7V. The 'H' designation specifically denotes the inclusion of half-array write protection capabilities.

Memory IC Replacement Considerations

The 24FC04H-I/SN serves as the industrial temperature version of this component. Other 24FC04H variants are available in different packages such as TSSOP or UDFN.
