Microchip Technology Inc., a leading provider of microcontroller, analog, and Flash-IP solutions, today announced from the SID Display Week show in Seattle the availability of mTouch Projected Capacitive Touch-Screen Sensing Technology, the first in a series of patent-pending releases supporting projected capacitive touch-screen solutions across the Company’s portfolio of 8-, 16- and 32-bit PIC MCUs. Microchip also announced the mTouch Projected Capacitive Development Kit today, as well as the PIC16F707 8-bit microcontroller (MCU), featuring two 16-channel Capacitive Sensing Modules (CSMs) that can run in parallel for increased sampling speed. The MCU is available today for just $0.99 each in volume and, along with the mTouch projected-capacitive technology and development kit, enables designers to easily integrate projected capacitive touch-sensing functionality into their application with a single MCU, thus reducing total system costs and increasing design flexibility.
Touch sensing continues to gain traction as an alternative to traditional push-button user interfaces, because it enables a more flexible, intuitive interface with a modern-looking design. mTouch projected capacitive touch-screen technology enables customers to quickly develop and implement robust glass-front user interfaces that simplify user interaction via features such as gestures. Typical applications include global positioning systems, thermostats, mobile handheld units and other devices that use smaller displays with a finger input.
mTouch Projected Capacitive Development Kit
The mTouch Projected Capacitive Development Kit (part # DM160211, $119.99) includes a 3.5” sensor mounted on a sensor board, a projected-capacitive board with the PIC16F707 MCU and fully functional firmware. The kit enables users to connect sensors to up to 24 channels, without modifying the firmware. The open source code supports sensors with up to 32 channels, and the kit includes a Graphical User Interface (GUI) tool that enables customers to easily adjust key parameters that are important to their design.
PIC16F707 Microcontroller
PIC16F707 - versatile 40-pin device offers 32 Capacitive Touch channels and is a member of Microchip's eXtreme Low Power family featuring nanoWatt XLP(TM) Technology
In addition to two CSMs, the low-power PIC16F707 8-bit MCU has a wide operating voltage range of 1.8 – 5.5V, with a typical projected-capacitive sensor application operating current of approximately 1.5 mA at 5V. A 40-pin, 5 mm x 5 mm micro QFN (µQFN) package option is expected to be available in Calendar Q3 2010. The MCU is available now, in 44-pin, 8 mm x 8 mm QFN and TQFP packages, for $0.99 each in volume.
