24LC014HT-E/ST

Memory IC Overview

The Microchip Technology 24LC014HT-E/ST is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I²C™ compatible 2-wire serial interfaces with clock frequencies up to 1 MHz. The device features hardware write protection for half the array, low-power CMOS technology, and extended temperature range operation from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Low-power design ensures minimal active and standby current consumption during operation.
• Schmitt trigger inputs provide enhanced noise suppression for reliable data transmission.
• Page write capability allows efficient storage of multiple bytes within a single physical page.

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in automotive electronics
• Calibration data storage in consumer devices

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors. Ensure the specific variant meets the voltage and interface requirements of the target application before procurement.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C communication is required alongside extended temperature stability. It is suitable for applications needing hardware write protection and low power consumption. Compare against the 24AA014H series if lower voltage operation down to 1.7V is necessary instead of the 2.5V minimum.

Memory IC Part Context

This part belongs to the 24LC014H family of 1 Kbit EEPROMs designed for serial data storage. It shares functional similarities with other members of the 24AA/24LC series but is distinguished by its higher clock speed compatibility and specific voltage operating range. The 'HT' suffix typically indicates tape and reel packaging for automated assembly.

Memory IC Replacement Considerations

The 24LC014H-I/ST is a compatible alternative offering the same functionality with an industrial temperature range (-40°C to +85°C).
