24LC16BT/SN

Memory IC Overview

The Microchip Technology 24LC16BT/SN 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, supporting clock frequencies up to 400 kHz for VCC between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes low-power CMOS technology. Key electrical characteristics include a maximum standby current of 5 μA and a maximum active read current of 1 mA.

Memory IC Feature Summary

• Hardware write protection via the WP pin inhibits all write operations when tied to VCC
• Schmitt trigger inputs and filter circuits suppress noise spikes on SDA and SCL lines
• Self-timed erase/write cycles utilize a 16-byte page write buffer for efficient data storage
• Output slope control eliminates ground bounce during signal transitions

Memory IC Applications

• Embedded systems requiring non-volatile data retention
• Industrial control devices operating in noisy environments
• Low-power battery-operated electronic equipment

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm the specific voltage requirements align with the 2.5V minimum threshold defined for the 24LC16B series. Ensure compatibility with existing I²C bus pull-up resistor configurations before finalizing procurement.

Memory IC Selection Notes

Select this component for applications requiring hardware-level write protection and robust noise immunity through Schmitt triggers. The 24LC16BT/SN is suitable for designs needing a single-chip solution for small data storage without external address pins. Consider the 400 kHz speed limit and 16-byte page write constraint when designing the communication protocol for optimal throughput.

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 variants but is distinguished by its specific 2.5V to 5.5V operating voltage range and 400 kHz maximum clock frequency. The device is RoHS compliant and designed for surface-mount integration.
