24AA08/S15K

Memory IC Overview

The Microchip Technology 24AA08/S15K is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V, supporting low-power CMOS technology with maximum read current of 1 mA and standby current of 1 µA. It includes hardware write-protect capabilities, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes a 16-byte page write buffer for efficient data storage operations
• Features hardware write protection controlled by the WP pin state
• Provides high ESD protection exceeding 4,000V on all pins

Memory IC Applications

• In-process monitoring systems requiring non-volatile data retention
• Robotic measurement systems utilizing laser ultrasonic techniques
• Industrial applications necessitating reliable memory in noisy environments

Memory IC Procurement Notes

Verify the specific suffix 'S15K' against official Microchip documentation to confirm package type and temperature grade availability. Ensure compatibility with the required operating voltage range of 1.7V to 5.5V. Confirm that the selected package supports the necessary hardware write-protect feature if applicable to your design.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation down to 1.7V and robust noise immunity through Schmitt triggers. Consider the 16-byte page write capability for improved throughput compared to byte-write operations. Ensure the application environment falls within the specified industrial or extended temperature ranges depending on the specific variant selected.

Memory IC Part Context

This EEPROM belongs to the 24XX08 family, which also includes the 24LC08B and 24FC08 devices. While sharing similar architectural features, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA08 specifically supports operation down to 1.7V, distinguishing it from the 2.5V minimum requirement of the 24LC08B.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX08 family such as the 24LC08B or 24FC08, provided voltage and speed requirements are met. Verify package compatibility and temperature ratings when cross-referencing with competitor parts.
