24AA08-I/SN

Memory IC Overview

The Microchip Technology 24AA08-I/SN is an 8-Kbit (1K x 8) Electrically Erasable PROM (EEPROM) housed in an 8-Lead SOIC package. 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 industrial temperature ranges from -40°C to +85°C and features a two-wire I²C compatible serial interface.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V
• Hardware write-protect capability via the WP pin
• Schmitt trigger inputs for noise suppression

Memory IC Applications

• Data logging systems
• Configuration storage
• Parameter memory

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the '/SN' suffix corresponds to the 8-Lead Small Outline Integrated Circuit (SOIC) package type. Ensure the component matches the specific 24AA08 variant rather than the 24LC08B or 24FC08 series, as voltage thresholds differ.

Memory IC Selection Notes

Select this part when low-voltage operation starting at 1.7V is required. The 24AA08 differs from the 24LC08B, which requires a minimum of 2.5V. The 24FC08 offers higher speed but shares the 1.7V lower limit. Verify that the 400 kHz clock rate meets system timing requirements.

Memory IC Part Context

This component belongs to the 24XX08 family of 8-Kbit serial EEPROMs. It shares architectural similarities with the 24LC08B and 24FC08 devices but is distinguished by its specific voltage operating range and clock frequency specifications defined within the datasheet.

Memory IC Replacement Considerations

Direct substitutes include other 24AA08 variants with different packages such as 24AA08-I/P (PDIP) or 24AA08T-I/MS (MSOP). Cross-family replacements like 24LC08B require checking voltage compatibility.
