Application Specific Microcontrollers datasheet and documents for CY8CTMA140-LQI-01

CY8CTMA140-LQI-01

Application Specific Microcontrollers Overview

The CY8CTMA140-LQI-01 is a TrueTouch® Multi-Touch All-Points Touchscreen Controller designed for capacitive sensing applications. It supports up to two independent fingers and handles screen sizes up to 3.2 inches diagonal with a standard sensor pitch, or up to 7 inches with stretched pitch. The device features 32 sense pins capable of sensing up to 132 intersections. It operates on an unregulated dual-rail supply configuration, accepting digital voltages from 1.71 V to 3.6 V and analog voltages from 2.7 V to 3.6 V, or a single shared supply within the 2.7 V to 3.6 V range.

Application Specific Microcontrollers Feature Summary

Tracks up to two fingers independently with noise-free resolution of 0.1 mm and accuracy of 0.5 mm.
Includes Charger Armor™ technology with adaptive frequency hopping for battery charger noise immunity.
Supports I2C slave interface up to 400 kHz and SPI slave interface with 2 Mbps sustained data throughput.
Features Smart noise suppression in LCD, battery charger, common-mode, and RF environments.

Application Specific Microcontrollers Applications

Capacitive touchscreen controllers for portable devices
Automotive infotainment systems requiring multi-touch input
Industrial control panels needing large object detection

Application Specific Microcontrollers Procurement Notes

Verify package availability as the datasheet indicates obsolete status. Confirm specific ordering suffixes for tape and reel versus tube packaging. Ensure compatibility with existing system voltage rails before procurement.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring up to two-finger tracking on screens up to 3.2 inches. Consider the CY8CTMA140-48LQI-01(T) if four-finger support or larger node counts are required. Verify that the application environment benefits from the integrated Charger Armor™ technology.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress TrueTouch Standard Product family. It utilizes PSoC technology to integrate programmable analog and digital resources for capacitive touch sensing. The LQI suffix denotes the industrial temperature range and the 36-pin QFN package type.

Application Specific Microcontrollers Replacement Considerations

The document states the spec is obsolete with no direct replacement listed. Evaluate the CY8CTMA140-48LQI-01(T) for increased finger support or the CY8CTMA1036AS-23 for automotive-specific requirements.
