24AA014-I/MS

Memory IC Overview

The Microchip Technology 24AA014-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 supports I²C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features hardware write protection, a page write buffer for up to 16 bytes, and an industrial temperature range of -40°C to +85°C. It is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports low-voltage operation down to 1.7V with low standby and active current consumption.
• Includes hardware write protection via the WP pin to inhibit write operations when tied high.
• Features a page write buffer allowing sequential storage of up to 16 bytes before internal programming.

Memory IC Applications

• Data logging in battery-powered devices
• Configuration storage in embedded systems
• Parameter retention in industrial controllers

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C) and 'MS' denotes the 8-lead MSOP package. Confirm RoHS compliance status as specified in the manufacturer's documentation. Ensure the application circuit respects the absolute maximum ratings for VCC and input voltages to prevent permanent damage.

Memory IC Selection Notes

Select this component for applications requiring non-volatile data retention with low power consumption. The 1.7V minimum operating voltage makes it suitable for systems powered by single lithium cells or low-voltage regulators. The 400 kHz interface speed supports moderate data throughput requirements.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs. The 'AA' prefix indicates support for operation down to 1.7V, distinguishing it from the 'LC' variant which requires a minimum of 2.5V. The 'I' suffix specifies the industrial temperature rating.

Memory IC Replacement Considerations

The 24LC014-I/MS is a functional alternative within the same family but requires a minimum supply voltage of 2.5V instead of 1.7V. Verify voltage compatibility before substitution.
