24LC014HT-E/SN

Memory IC Overview

The Microchip Technology 24LC014HT-E/SN 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 utilizes a 2-wire I²C compatible serial interface with a maximum clock frequency of 1 MHz. The device features hardware write protection for half the array, supports page writes of up to 16 bytes, and offers data retention exceeding 200 years. It is housed in an 8-pin SOIC package and is rated for extended industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication
• Includes hardware write protection for the upper half of the memory array
• Features low-power CMOS technology with minimal standby current
• Provides Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial instrumentation
• Device identification and security code storage

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape and reel packaging as indicated by distributor specifications. Confirm the 'E' suffix aligns with the required automotive-grade extended temperature range (-40°C to +125°C). Ensure the 'SN' suffix matches the 8-lead SOIC package requirement for your PCB layout.

Memory IC Selection Notes

Select this component when a 1 MHz bus speed is necessary compared to standard 400 kHz EEPROMs. The hardware write protect pin is essential if physical protection against accidental overwrites to specific memory addresses is required. Verify that the 2.5 V minimum operating voltage is compatible with the system's power rails.

Memory IC Part Context

This part belongs to the 24LC014H family of 1 Kbit serial EEPROMs. It shares architectural similarities with the 24AA014H but differs in its lower minimum operating voltage specification. The device is designed for applications needing reliable, byte-addressable non-volatile memory with a compact footprint.
