LM8500IMT9

Overview

The LM8500IMT9 is a four-wire resistive touchscreen controller manufactured by National Semiconductor, now part of Texas Instruments. It integrates a high-resolution analog-to-digital converter and a serial interface for connecting to host processors. The device features an integrated brownout detector to ensure reliable operation during power supply transitions. Designed for embedded systems requiring touch input, it supports standard four-wire resistive panels with low power consumption characteristics suitable for portable applications.

Feature Summary

Four-wire resistive touchscreen controller
Integrated brownout detection circuit
Serial interface connectivity
High-resolution analog-to-digital conversion

Applications

Portable electronic devices
Embedded control panels

Part Context

This component belongs to the LM8500/LM8300 family of touchscreen controllers. National Semiconductor was acquired by Texas Instruments, and these parts are often referenced under TI documentation. The LM8500IMT9 specifically denotes the industrial temperature range variant in a TSSOP package.

Replacement Considerations

The LM8500IMT9B/NOPB is a direct replacement from Texas Instruments. Other compatible controllers include the Semtech SX8651 series for enhanced multitouch capabilities or the LM8300 for similar basic functionality.
