24LC014-I/ST

Memory IC Overview

The Microchip Technology 24LC014-I/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 features a 2-wire I²C compatible serial interface with clock frequencies up to 400 kHz. The device supports hardware write protection via the WP pin, page writes of up to 16 bytes, and offers data retention exceeding 200 years with 1,000,000 erase/write cycles endurance. It is housed in an 8-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication using I²C protocol
• Includes hardware write protection for the entire memory array
• Features a page write buffer allowing transfers of up to 16 bytes
• Provides high reliability with extended data retention and endurance

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices needing parameter logging
• Consumer electronics utilizing low-power memory solutions
• Automotive applications compatible with standard bus protocols

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' confirms the Industrial temperature grade (-40°C to +85°C) and TSSOP-8 package type. Ensure the design accounts for the 2.5V minimum operating voltage, as this variant differs from the 1.7V capable 24AA014 series. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is required with I²C connectivity and industrial temperature stability. It is suitable for designs where hardware write protection is necessary to prevent accidental data corruption. Choose this over the 24AA014 if the system power rail does not support voltages below 2.5V during operation or brown-out conditions.

Memory IC Part Context

This part belongs to the 24LC014 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA014 but is distinguished by its higher minimum operating voltage requirement. The device is designed to integrate seamlessly into microcontroller-based systems requiring persistent storage for configuration data or small datasets.

Memory IC Replacement Considerations

The 24AA014-I/ST serves as a direct functional substitute, offering identical memory organization and interface but supporting operation down to 1.7V. Designers must verify that their power supply rails remain above 2.5V to ensure proper functionality when substituting between these variants.
