PIC® Microcontrollers with mTouchTM 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 simplifi es 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 8-bit PIC® Microcontroller Solutions 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. Development Tools Enhanced mTouch™ Capacitive Evaluation Kit (DM183026-2) ■ Features PIC16F, PIC18F, PIC24F and PIC32F ■ Includes 8 buttons, matrix and sliders daughter boards ■ GUI for easy confi guration and real time data monitoring Metal Over Cap Accessory Kit (AC183026) ■ For use with the DM183026-2 ■ 1 daughter board featuring stainless steel cover ■ 1 daughter board featuring a plastic cover Featured HCVD Product Families Device Pins Flash/RAM HCVD Voltage (V) Additional Features PIC12LF1552 8 3.5 KB 256B  1.8–3.6 10-bit ADC (4), SPI/I2C™ PIC16LF1554 14 7 KB 256B  1.8–3.6 10-bit ADC (11), EUSART, SPI/I2C PIC16LF1559 20 14 KB 512B  1.8–3.6 10-bit ADC (17), EUSART, SPI/I2C Software CVD available on all PIC MCUs with ADC www.microchip.com/mtouch
