24AA014T-I/MC

Memory IC Overview

The 24AA014T-I/MC is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM manufactured by Microchip Technology. It operates on a single supply voltage ranging from 1.7V to 5.5V and features a 2-Wire Serial Interface compatible with the I²C™ bus. The device supports clock frequencies of 100 kHz and 400 kHz, with a maximum write cycle time of 5 ms. It includes hardware write protection for the entire array and offers data retention exceeding 200 years with 1,000,000 erase/write cycles endurance. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports low-power CMOS technology with typical standby current of 1 µA at 5.5V
• Includes hardware write protection circuitry to inhibit write operations when enabled
• Features a page write buffer capable of storing up to 16 bytes of data
• Provides high ESD protection ratings exceeding 4,000V on all pins

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I²C bus communication
• Embedded systems operating within the industrial temperature range

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'MC' denotes the 8-lead MSOP package. Confirm the 'T' suffix indicates tape and reel packaging if required for automated assembly. Ensure the specific part number matches the 24AA014 series specifications rather than the 24LC014 variant, particularly regarding the minimum operating voltage requirements for your application design.

Memory IC Selection Notes

Select this component when a small memory footprint of 1 Kbit is sufficient for system configuration or calibration data. It is suitable for designs requiring operation down to 1.7V, making it ideal for battery-powered applications where power efficiency is critical. The hardware write protect feature provides a robust method for safeguarding critical data against accidental modification. Ensure the host microcontroller supports the required I²C protocol speeds and voltage levels compatible with the 1.7V to 5.5V range.

Memory IC Part Context

This device belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs. The 24AA014 variant is distinguished by its ability to operate at lower voltages starting from 1.7V, whereas the 24LC014 typically requires a minimum of 2.5V. Both share identical pinouts and functional interfaces but differ in electrical characteristics related to supply voltage ranges. The T/I/MC designation specifies the industrial temperature grade and surface-mount MSOP packaging format.

Memory IC Replacement Considerations

The 24LC014T-I/MC serves as a direct pin-compatible alternative, provided the system supply voltage remains above 2.5V. Other members of the 24XX014 family may be considered if voltage or temperature requirements align. Verify that any substitute maintains the same I²C compatibility and package dimensions to ensure seamless integration without PCB redesign.
