24AA52T-I/SN

Memory IC Overview

The Microchip 24AA52T-I/SN is a 2 Kbit (256 x 8) serial Electrically Erasable PROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 1.8V to 5.5V with industrial temperature support (-40°C to +85°C). The device supports clock frequencies up to 400 kHz and includes hardware write protection via the WP pin, alongside software-based protection for the lower half of the array.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication compatible with the I²C protocol
• Provides hardware write protection for the entire memory array through the dedicated WP pin
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce

Memory IC Applications

• Low-power data acquisition systems requiring non-volatile storage
• Personal communications devices operating on limited power supplies
• Industrial control applications needing reliable parameter retention across wide voltage ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package type as specified in the datasheet. Confirm the 'I' designation indicates the Industrial temperature range (-40°C to +85°C). Ensure the 'T' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application requirements. Choose this part over the 24LCS52 variant if operation below 2.2V is necessary, as the 24AA52 series supports voltages down to 1.8V. Ensure the system design accommodates the specific page write buffer size and timing constraints defined in the electrical characteristics.

Memory IC Part Context

This device belongs to the 24AA52/24LCS52 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including low-power CMOS technology and robust ESD protection. Variants within the family differ primarily in voltage thresholds and maximum clock speeds, allowing designers to optimize for specific power and speed requirements.

Memory IC Replacement Considerations

The 24LC52 serves as a functional replacement within the same family, though it requires a minimum supply voltage of 2.5V compared to the 24AA52's 1.8V minimum. Designers must verify voltage compatibility before substituting.
