24LC16BT-I/OTG

Memory IC Overview

The Microchip Technology 24LC16BT-I/OTG is a 16-Kbit Electrically Erasable PROM organized as eight 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 2.5V to 5.5V, supporting maximum clock frequencies of 400 kHz within this range. It utilizes low-power CMOS technology, ensuring standby current remains at or below 1 μA and active read current does not exceed 1 mA. The component supports page write operations with a buffer capacity of up to 16 bytes.

Memory IC Feature Summary

• Features hardware write protection via the WP pin to inhibit write operations when tied to VCC.
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination.
• Supports self-timed erase/write cycles with acknowledge polling capabilities to maximize bus throughput.
• Provides high reliability with over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices needing reliable parameter logging
• Consumer electronics utilizing I²C communication buses

Memory IC Procurement Notes

Verify the specific suffix 'OTG' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the industrial temperature grade (I) matches application requirements. Confirm RoHS compliance status through current datasheets. Check for any recent product change notices affecting availability or marking information before finalizing procurement plans.

Memory IC Selection Notes

Select this component for applications requiring 16-Kbit non-volatile storage with I²C interface compatibility. It is suitable for designs operating between 2.5V and 5.5V where low standby power is critical. Consider the 5-lead SOT-23 package for space-constrained layouts. Verify that the 400 kHz clock speed meets system timing requirements and that hardware write protection aligns with security needs.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA16 and 24FC16 variants but differs in minimum operating voltage and maximum clock frequency specifications. The device is designed for general-purpose data storage in microcontroller-based systems requiring persistent memory without complex interfaces.

Memory IC Replacement Considerations

Direct replacements include other 24LC16B variants with different packages such as SOIC or TSSOP. Cross-family alternatives like 24AA16 offer lower voltage operation but reduced clock speeds below 2.5V. Ensure pin compatibility and electrical characteristics match before substituting.
