1. Overview

The AT42QT2160-MMU (QT2160) is designed for use with up to 16 keys and a slider

(constructed from 2 keys up to 8 keys). There are three dedicated General Purpose

Input/Outputs (GPIOs) which can be used as inputs for mechanical switches etc. or as driven

outputs. There are eight shared General Purpose Outputs (GPOs) (X0...X7) which are driven

outputs only. There is PWM control for all GPIO/GPOs.

The QMatrix™ technology employs transverse charge-transfer sensing electrode

designs which can be made very compact and are easily wired. Charge is forced from

an emitting electrode into the overlying panel dielectric, and then collected on a

receiver electrode. This directs the charge into a sampling capacitor which is then

converted directly to digital form, without the use of amplifiers.

The keys are configured in a matrix format that minimizes the number of required scan

lines and device pins. The key electrodes can be designed into a conventional Printed

Circuit Board (PCB) or Flexible Printed Circuit Board (FPCB) as a copper pattern, or

as printed conductive ink on plastic film.
