24LC04BHT-E/MS

Memory IC Overview

The Microchip Technology 24LC04BHT-E/MS is a 4-Kbit (512 x 8) serial EEPROM featuring an I2C-compatible two-wire 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 protection for the upper half of the memory array, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead MSOP 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
• 16-byte page write buffer for efficient data transfer
• Schmitt trigger inputs with spike suppression for noise immunity
• Output slope control designed to eliminate ground bounce

Memory IC Applications

• Embedded systems requiring non-volatile parameter storage
• Industrial controllers needing high endurance memory
• Automotive electronics utilizing AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix correctly specifies the MSOP package and Extended temperature grade. Confirm RoHS compliance status as required by project specifications. Ensure the selected variant matches the specific voltage and speed requirements of the target application circuit design.

Memory IC Selection Notes

Select this component when half-array write protection is necessary to secure critical data. The MSOP package is suitable for space-constrained surface mount designs. Verify that the system voltage remains above 2.5V to ensure proper operation at the specified 400 kHz clock frequency.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit serial EEPROMs. It shares functional similarities with the 24AA04H and 24FC04H but differs in minimum operating voltage and maximum clock speed capabilities. The 'BH' designation indicates the specific electrical characteristics and features of this sub-family.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04BH variants with different packages such as 24LC04BH-E/P or 24LC04BH-E/MS. Cross-referencing with the 24AA04H or 24FC04H families requires verification of voltage and speed compatibility.
