24AA014T-I/MS

Memory IC Overview

The Microchip Technology 24AA014T-I/MS is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V 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 acknowledge polling. It is housed in an 8-lead MSOP package and rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling typical standby current of 1 µA and active current of 1 mA
• Hardware write protection for the entire array controlled by the WP pin
• Page write buffer supporting up to 16 bytes per write cycle
• High reliability with 1,000,000 erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage operation
• Embedded systems needing compact serial EEPROM solutions

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the MSOP package type aligns with the target PCB footprint. Cross-reference the full part number against the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices.

Memory IC Selection Notes

Select this component for applications requiring robust data retention and high endurance within a small surface-mount package. The wide supply voltage range facilitates integration into both 1.8V and 5V systems. The I²C interface simplifies connectivity with microcontrollers, while the hardware write protection ensures critical data integrity against accidental overwrites.

Memory IC Part Context

This device belongs to the 24AA014/24LC014 family of 1 Kbit serial EEPROMs. It shares functional similarities with the 24LC014 but differs in minimum operating voltage, supporting operation down to 1.7V compared to the 24LC014's 2.5V minimum. Both variants utilize the same I²C protocol and physical pinout configurations across various packages.

Memory IC Replacement Considerations

The 24LC014T-I/MS serves as a direct functional substitute, provided the system voltage remains above 2.5V. Other members of the 24AA014 series with different package suffixes may replace this unit if form factor adjustments are permissible.
