24AA512SC-I/W17K

Memory IC Overview

The Microchip Technology 24AA512SC-I/W17K is a 512 Kbit (64K x 8) serial electrically erasable programmable read-only memory device. It features an I²C interface with a maximum clock frequency of 400 kHz and operates across a supply voltage range of 1.7 V to 5.5 V. The component utilizes wafer-on-frame packaging, providing access to the die for specialized integration. It supports page write capabilities of up to 128 bytes and ensures data retention for extended periods.

Memory IC Feature Summary

• Supports standard I²C communication protocols with high-speed mode capability
• Operates reliably across a wide voltage range suitable for battery-powered systems
• Features robust data retention characteristics verified through rigorous testing

Memory IC Applications

• Smart card applications requiring ISO 7816 compatibility
• Data acquisition systems needing non-volatile storage
• Personal communications devices utilizing low-power memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'W17K' against official Microchip documentation to confirm wafer-on-frame specifications and lead times. Ensure the industrial temperature grade matches your environmental requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 512 Kbit capacity is required within a smart card or wafer-level form factor. Compare against the 24LC512 series if standard packaged options are acceptable, noting that the 24AA series offers a lower minimum operating voltage. Verify bus speed requirements against the 400 kHz limit for adequate system performance.

Memory IC Part Context

This device belongs to the 24AA family of serial EEPROMs designed for advanced low-power applications. It shares architectural similarities with other 512 Kbit devices in the portfolio but distinguishes itself through its specific wafer-on-frame packaging option, catering to embedded control markets requiring compact memory solutions.

Memory IC Replacement Considerations

The 24LC512 serves as a functional alternative for standard packaged implementations, though it requires a higher minimum voltage. Direct pin-compatible replacements should be verified using Microchip's MAPS tool to ensure electrical parameter alignment.
