24LC16BT-E/OT

Memory IC Overview

The Microchip Technology 24LC16BT-E/OT is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device supports I²C compatible two-wire serial interface and features Schmitt trigger inputs for noise suppression. It includes hardware write protection, output slope control, and a 16-byte page write buffer. The component is qualified under AEC-Q100 standards and functions within an extended temperature range of -40°C to +125°C.

Memory IC Feature Summary

• AEC-Q100 automotive qualification for reliability in demanding environments
• Hardware write-protect capability via the WP pin to secure data integrity
• Output slope control designed to eliminate ground bounce during operation
• Self-timed erase/write cycles with automatic internal timing management

Memory IC Applications

• Automotive embedded systems requiring non-volatile data storage
• Industrial equipment operating in high-noise environments
• Consumer electronics utilizing low-power I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'OT' indicates the 5-Lead SOT-23 package configuration. Confirm AEC-Q100 compliance requirements match your specific application standards. Ensure voltage levels align with the 2.5V minimum operational threshold specified for the 24LC16B series.

Memory IC Selection Notes

Select this component when automotive-grade reliability and extended temperature performance are required. The 24LC16BT variant specifically addresses the need for robustness in harsh conditions compared to standard industrial grades. Consider the SOT-23 package if space constraints dictate a smaller footprint than SOIC or DIP options.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 devices but differs in voltage specifications and speed capabilities. The 24LC16B series is optimized for 2.5V to 5.5V operations, distinguishing it from lower-voltage alternatives within the same product line.

Memory IC Replacement Considerations

Direct replacements include other 24LC16B variants with different packages such as 24LC16BT-I/SN for industrial temperature ranges. Cross-reference package types carefully, as physical dimensions vary between SOT-23, SOIC, and DFN formats while maintaining electrical compatibility.
