24LC04BHT-E/SN

Memory IC Overview

The Microchip Technology 24LC04BHT-E/SN is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C serial interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write-protect capabilities for half the array, Schmitt trigger inputs for noise suppression, and output slope control. 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-protect capability for the upper half of the memory array
• Schmitt trigger inputs with spike suppression for noise immunity
• Output slope control designed to eliminate ground bounce
• Self-timed erase/write cycles with page write buffer

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter retention in automotive electronics
• Smart metering applications requiring non-volatile data storage

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the ordering code matches the required voltage and speed specifications for your design.

Memory IC Selection Notes

Select this component when half-array write protection is required alongside standard I2C compatibility. The extended temperature rating makes it suitable for harsh environments where standard industrial grades may fail. Verify that the 2.5V minimum supply voltage aligns with the system power rails.

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 24FC04H but is distinguished by its 2.5V minimum operating voltage requirement compared to the 1.7V minimum of the other variants in the series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04BH variants with different packages such as 24LC04BHT-I/SN or 24LC04BHT-E/MSOP, provided the temperature grade and package dimensions are compatible with the PCB layout.
