24LC04BHT-E/ST

Memory IC Overview

The Microchip Technology 24LC04BHT-E/ST is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C compatible 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 TSSOP package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection
• Schmitt trigger inputs with spike suppression for noise immunity
• Output slope control 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 consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'ST' denotes the TSSOP package. Confirm RoHS compliance status as required by project specifications. Ensure the ordering code matches the exact pinout and electrical characteristics defined in the official datasheet DS20002119C.

Memory IC Selection Notes

Select this component when a 4-Kbit non-volatile memory solution is required with I2C connectivity. The extended temperature grade makes it suitable for harsh environments where standard industrial grades are insufficient. 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 serial EEPROMs, which share common architectural features such as the 16-byte page write buffer and half-array write protection. The 'BH' designation indicates the 400 kHz clock speed variant, distinguishing it from higher-speed models within the broader product line.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04BH variants with different packages, such as 24LC04BHT-I/SN or 24LC04BHT-E/MS, provided the temperature and package constraints are met.
