24AA014-I/SN

Memory IC Overview

The Microchip Technology 24AA014-I/SN 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 SOIC package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the entire array
• Page write buffer supporting up to 16 bytes
• Acknowledge polling capability for bus throughput optimization

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-power I²C interfaces
• Embedded systems needing configuration parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and the 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status as per the latest manufacturer 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 when a 1 Kbit capacity is required with I²C connectivity. It is suitable for designs operating at voltages as low as 1.7V. Consider the 400 kHz speed limit and page write constraints. Verify that the physical layout accommodates the 8-lead SOIC footprint and that pull-up resistors are correctly sized for the bus capacitance.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs. The 'AA' designation typically indicates operation down to 1.7V, distinguishing it from variants like the 24LC014 which may have different minimum voltage requirements. The family shares identical pinouts and functional protocols across various package options.

Memory IC Replacement Considerations

The 24LC014-I/SN is a functionally similar alternative within the same datasheet, though it specifies a minimum operating voltage of 2.5V compared to the 24AA014's 1.7V minimum. Other 1 Kbit I²C EEPROMs from different manufacturers require verification of voltage ranges and timing parameters.
