24AA014-I/ST

Memory IC Overview

The Microchip Technology 24AA014-I/ST is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM featuring a 2-Wire I²C compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device supports hardware write protection, page writes 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 rated for industrial temperature ranges.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V with minimal standby current
• Hardware write protection capability for the entire memory array via the WP pin
• I²C compatible 2-wire serial interface supporting standard and fast mode clock frequencies
• Page write buffer allowing sequential storage of up to 16 bytes per cycle

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing compact serial EEPROM solutions
• Automotive applications within specified temperature grades

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the Industrial temperature grade (-40°C to +85°C) and TSSOP-8 package configuration. Confirm that the ordering part number matches the exact datasheet revision DS21809G. Ensure compatibility with system voltage levels between 1.7V and 5.5V before procurement.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is required with I²C connectivity. The 24AA014 series is suitable for applications demanding low standby current and hardware-level write protection. Consider the TSSOP package for surface-mount assembly constraints. Verify that the operating environment falls within the industrial temperature range specifications.

Memory IC Part Context

This device belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in voltage ranges and temperature grades. The 24AA014 variant specifically supports lower voltage operation starting at 1.7V compared to other variants in the lineup.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24AA014 family such as the 24AA014-E/ST for extended automotive temperatures. Cross-family replacements like the 24LC014 may require voltage level verification as they typically start at 2.5V minimum.
