CAP1128

8 Channel Capacitive Touch Sensor

with 2 LED Drivers

Datasheet

PRODUCT FEATURES

General Description

The CAP1128, which incorporates SMSC’s RightTouch

technology, is a multiple channel Capacitive Touch sensor

with multiple power LED drivers. It contains eight (8)

individual capacitive touch sensor inputs with

programmable sensitivity for use in touch sensor

applications. Each sensor input automatically recalibrates

to compensate for gradual environmental changes.

Applications

Desktop and Notebook PCs

LCD Monitors

Consumer Electronics

Appliances

Features

Eight (8) Capacitive Touch Sensor Inputs

—

Programmable sensitivity

The CAP1128 also contains two (2) LED drivers that offer

full-on / off, variable rate blinking, dimness controls, and

breathing. Each of the LED drivers may be linked to one of

the sensor inputs to be actuated when a touch is detected.

As well, each LED driver may be individually controlled via

a host controller.

Automatic recalibration

Individual thresholds for each button

Proximity Detection

Multiple Button Pattern Detection

Calibrates for Parasitic Capacitance

Analog Filtering for System Noise Sources

The CAP1128 includes Multiple Pattern Touch recognition

that allows the user to select a specific set of buttons to be

touched simultaneously. If this pattern is detected, then a

status bit is set and an interrupt generated.

Press and Hold feature for Volume-like Applications

Multiple Communication Interfaces

—

SMBus / I²C compliant interface

SMSC BC-Link interface

SPI communications

Additionally, the CAP1128 includes circuitry and support for

enhanced sensor proximity detection.

Pin selectable communications protocol and multiple

The CAP1128 offers multiple power states operating at low

quiescent currents. In the Standby state of operation, one

or more capacitive touch sensor inputs are active and all

LEDs may be used. If a touch is detected, it will wake the

system using the WAKE/SPI_MOSI pin.

slave addresses (SMBus / I²C only)

Low Power Operation

—

5uA quiescent current in Deep Sleep

50uA quiescent current in Standby (1 sensor input

monitored)

Deep Sleep is the lowest power state available, drawing

5uA (typical) of current. In this state, no sensor inputs are

active. Driving the WAKE/SPI_MOSI pin or communications

will wake the device.

—

Samples one or more channels in Standby

Two (2) LED Driver Outputs

—

Open Drain or Push-Pull

Programmable blink, breathe, and dimness controls

Can be linked to Capacitive Touch Sensor inputs

Dedicated Wake output flags touches in low power state

System RESET pin

Available in 20-pin 4mm x 4mm QFN RoHS compliant

package
