24LC014H-I/SN

Memory IC Overview

The Microchip Technology 24LC014H-I/SN is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features a 2-wire I²C compatible interface with a maximum clock frequency of 1 MHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports industrial temperature ranges from -40°C to +85°C. It utilizes low-power CMOS technology, offering a maximum active current of 400 μA and standby current of 1 μA. The component includes hardware write protection for half the array and provides data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication alongside standard 100 kHz and 400 kHz modes.
• Includes hardware write protection capability that secures the upper half of the memory array.
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides a page write buffer allowing up to 16 bytes to be written in a single operation.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify the specific suffix 'I/SN' corresponds to the Industrial temperature grade (-40°C to +85°C) and SOIC-8 package. Confirm the voltage range requirement matches the 2.5V minimum specification for the LC variant, distinct from the AA series. Ensure the design accounts for the 1 MHz clock limit when operating at higher supply voltages.

Memory IC Selection Notes

Select this component when an I²C interface is required with speeds up to 1 MHz. It is suitable for applications needing hardware write protection for critical data segments. Consider the 128-byte organization and 16-byte page buffer for efficient data handling. Ensure the system voltage remains above 2.5 V to maintain full functionality.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs. The 'LC' designation indicates support for 1 MHz clock frequencies, whereas the 'AA' counterpart is limited to 400 kHz. The 'SN' suffix identifies the 8-pin Small Outline Integrated Circuit (SOIC) package type.

Memory IC Replacement Considerations

The 24AA014H-I/SN is a functional substitute but is limited to a 400 kHz maximum clock frequency. Other 1 Kbit I²C EEPROMs may require verification of voltage compatibility and pin configuration.
