24LC014T-E/ST

Memory IC Overview

The Microchip Technology 24LC014T-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 2.5 V to 5.5 V and features a 2-wire I²C compatible serial interface with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, supporting up to one million erase/write cycles and retaining data for over 200 years. It is housed in an 8-lead TSSOP package and is rated for an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection capability via the WP pin to inhibit write operations across the entire array
• Page write buffer supporting up to 16 bytes of data for efficient sequential writing
• Self-timed write cycle with automatic erase-before-write functionality
• Supports multiple device addressing allowing up to eight units on a single bus

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in automotive electronics
• Parameter storage in consumer appliances

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging and '/ST' confirms the TSSOP-8 package type. Confirm the 'E' suffix denotes the extended temperature grade (-40°C to +125°C) required for your application environment. Ensure compatibility with the 2.5V minimum supply voltage constraint before integration.

Memory IC Selection Notes

Select this component when an I²C interface is required for non-volatile storage in space-constrained designs utilizing surface-mount assembly. The extended temperature rating makes it suitable for harsh environments where standard industrial grades may fail. Consider the page write size if high-throughput data logging is necessary to optimize bus efficiency.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1-Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical memory architecture and electrical characteristics, differing primarily in operating voltage ranges and temperature grades. The 24LC series specifically supports lower voltage operation starting at 2.5V compared to the 24AA series.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification include the 24LC014-I/ST for industrial temperature range applications. Other package variants such as 24LC014-P or 24LC014-SN offer equivalent functionality with different physical footprints.
