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.
