24LC014T-I/ST

Memory IC Overview

The Microchip Technology 24LC014T-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 2.5 V to 5.5 V and features a 2-wire I²C compatible serial interface with a maximum clock frequency of 400 kHz. The device supports hardware write protection via the WP pin, page write buffers for up to 16 bytes, and acknowledge polling. It is housed in an 8-lead TSSOP package and is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission using I²C compatible protocol
• Includes hardware write protection circuitry to inhibit write operations when enabled
• Features a page write buffer allowing storage of up to 16 bytes before internal write cycle initiation
• Provides acknowledge polling capability to determine completion of internally timed write cycles

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded microcontrollers
• Parameter retention in low-power consumer electronics
• Device identification and calibration data storage

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status as specified in the manufacturer documentation. Ensure the specific revision level aligns with design requirements. Check for any recent product change notices affecting electrical characteristics or packaging. Validate that the source document corresponds directly to the 24LC014T-I/ST part number.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with low power consumption and standard I²C connectivity. Consider the 400 kHz clock speed for moderate data throughput needs. Evaluate the 1 million erase/write cycle endurance against application write frequency. Ensure the 2.5 V minimum supply voltage meets system power rails. Verify that the TSSOP package dimensions fit the printed circuit board layout constraints.

Memory IC Part Context

This EEPROM belongs to the 24AA014/24LC014 family, which shares identical functional specifications but differs in supply voltage ranges and temperature grades. The 'LC' designation indicates operation down to 2.5 V, whereas 'AA' variants support lower voltages. The 'I' suffix denotes the industrial temperature range. Other packages include PDIP, SOIC, MSOP, DFN, and SOT-23 options within the same family.

Memory IC Replacement Considerations

Public confirmed substitutes include other 24LC014 variants with different packages such as 24LC014-I/SN or 24LC014-E/P. Cross-reference datasheets for pin compatibility and electrical parameter alignment. Verify that substitute parts maintain the same I²C addressing scheme and write protection logic.
