AK4187AKT

Overview

The AK4187AKT is a touch screen controller manufactured by Asahi Kasei Microdevices/AKM. It supports 4-wire resistive touch screens and features an I2C serial interface. The device is housed in a 16-TSSOP surface-mount package. It is designed for dual touch gesture recognition, providing digital processing capabilities for touch input applications.

Feature Summary

Supports dual touch gesture recognition
Integrates I2C serial communication interface
Compatible with 4-wire resistive touch panels

Applications

Resistive touch screen systems
Dual touch gesture input devices
Embedded control interfaces

Procurement Notes

Verify the exact part number suffix to ensure package compatibility, as variants like ZEN exist in QFN format. Confirm current availability status, as some listings indicate end-of-life or discontinuation for specific revisions. Cross-reference datasheet specifications against system requirements before procurement.

Selection Notes

Select this component when a dedicated controller for 4-wire resistive screens is required. Ensure the host system supports I2C communication protocols. Verify that the 16-TSSOP package fits the PCB layout constraints. Consider power supply voltage levels compatible with the specified operating range.

Part Context

This component belongs to the AK4187 series of touch screen controllers from Asahi Kasei Microdevices. The series focuses on resistive touch technologies with integrated gesture processing. It serves as a bridge between analog touch inputs and digital host processors via standard serial interfaces.

Replacement Considerations

The AK4187ZEN is a variant within the same family but utilizes a 16-QFN package instead of TSSOP. Verify pinout compatibility if substituting packages. No other direct functional substitutes are confirmed in public documentation.
