Description

The FMA1127 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. It includes touch sensor technology that

compares reference and sensor input impedances to detect touch,

all in digital domain.

Its programmability increases design flexibility and gives better

performance and stability for a broad range of applications. The

FMA1127’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 features of the FMA1127 touch sensor

controller, is the Adjacent Pattern Interference Suppression

(APIS™) which acts as a filter to eliminate adjacent key or

pattern interference. The FMA1127 also gives touch-strength

output in addition to touch on/off output. There are a number of

general-purpose DIOs depending on the package type that can be

configured and programmed to meet customers’specific needs. This

gives customers greater flexibility and value.

The FMA1127 comes in various package types to support different

numbers of input channels and DIOs.

The FMA1127 touch sensor controller is developed and owned by

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

Microelectronics America, Inc.

Features

• Patented full-digital architecture

• Supports 12 input channels (40QFN and 30SSOP) or 9 input

channels (32QFN and 24SSOP) or 6 input channels

(24QFN and 20SSOP)

• Programmable registers to characterize applications

• I2C interface with the host MCU

• Configurable Automatic Impedance Calibration (AIC™ )

• Two types of interrupts (GINT for general purpose and

TINT for touch detection)

• 8-bit resolution of touch strength data (256 steps)

• Three different modes for Adjacent Pattern Interference

Suppression (APIS™)

• Configurable DIO pins as direct touch outputs, extended

GPIOs, or external interrupt inputs.

• Beep generation for tactile feeling

• Idle and Sleep modes for power saving

• De-bounced touch outputs
