Overview

The FMA1127DC is a low-power, compact, flexible touch sensor

controller that converts capacitance generated between the human

body and a conductive touch pad to digital data without any analog

signal processing.

Its programmability increases design flexibility and gives better

performance and stability for a broad range of applications.The

FMA1127DC’s Automatic Impedance Calibration (AIC™) function

can be easily configured to support different sensitivities for

individual channels independently as well as to change values of

parameters, such as calibration intervals. AIC may also be

temporarily paused and resumed by a host MCU.

Among the many new features of the FMA1127DC is Adjacent

Pattern Interference Suppression (APIS™). APIS is a filtering

function that eliminates adjacent key or pattern interference. The

FMA1127DC also gives touch-strength output in addition to touch

on/off output.There is a number of DIOs depending on the package

type that can be configured and programmed to meet a customer’s

specific needs, giving customers even greater flexibility and value.

The FMA1127DC comes with various package types to support

different number of input channels and DIOs.

The FMA1127DC touch sensor controller is developed and owned by

ATLab Inc., South Korea, and is distributed by Fujitsu

Microelectronics America, Inc.
