PIC Microcontrollers with mTouch Technology

Touch Sensing

Touch sensing has become an alternative to traditional

push-buttons and switches providing:

■ Lower cost of manufacturing and assembly

■ Elegant and stylish designs

■ Increased reliability with fewer moving parts

■ Proximity-sensitive human interfaces

Microchip’s mTouch Sensing Solutions allow you to

integrate touch sensing with application code in a single

microcontroller, reducing total system cost. Microchip

offers a broad portfolio of low-power, low-cost and flexible

solutions for keys/sliders and touch screen controllers.

Get to market faster using our easy GUI-based tools, free

source code and low-cost development tools.

Keys, Sliders, Wheels and Proximity Detection

■ Industry’s lowest-power touch sense solutions

• Capacitive sensing in less than 5 μA

• Proximity sensing down to less than 1 μA

■ No external components

■ Works through plastic, glass and metal surfaces

■ Waterproof designs for all weather conditions

■ High noise robustness

■ Integrated peripherals such as USB, segmented and

graphical LCD modules for true human interface

system-on-a-chip

■ Free software library simplifies implementation and

source code puts you in control

Capacitive Voltage Divider (CVD)

CVD is a charge/voltage based technique to measure

relative capacitance on a pin using only the ADC.

■ Software implementation

■ 8, 16, and 32-bit support

■ Proximity sensing support

■ Low temperature dependence

■ Low VDD Dependence

■ Minimal hardware requirements

■ Low-frequency noise rejection

■ Metal over cap compatible

Hardware CVD

Hardware CVD (HCVD) has been implemented on some of our

new devices providing automated capacitive touch sampling,

thereby reducing code size and decreasing CPU usage.
