Microchip Touch and Input Sensing Solutions

title

Microchip Technology Inc. is an American manufacturer of microcontroller, memory and analogue semiconductors. Its products include microcontrollers (PICmicro, dsPIC/PIC24, PIC32), Serial SRAM devices, radio frequency devices, thermal, power and battery management analog devices, as well as linear, interface and mixed signal devices. Headquarters in Chandler, Arizona. It provides low-risk product development, low total system cost. In this article, we will focus on its touch and input sensing solutions and related products.

title

 Microchip's award winning technology covers a broad range of implementations for touch and other input sensing applications. With the help of its techniques, engineers can have the freedom to innovate with an industry leading, robust, touch implementation on Microchip’s vast range of PIC microcontrollers. It can be divided into four aspects: proximity, keys and Sliders; touch screen and touch pad controllers; 3D tracking and gesturing; haptics.

Proximity, Keys and Sliders

Firstly, let’s look at the Proximity, keys, Sliders and their related products. Microchip offers both turnkey products for a no code development plug-and-play solution, as well as a proven robust firmware solution that leverage their PIC microcontroller portfolio.

3D Tracking and Gesturing

Microchip’s E-field sensing technology detects the proximity of a human hand and gives accurate X-Y-Z coordinates and recognised 3D gesture. Microchip's MGC3130 is the world’s first electrical near field (E-field) 3D Gesture Controller. Based on Microchip’s patented GestIC® technology, it enables to detect gestures of the user and to track a movement. Interaction with devices becomes as simple and intuitive as a wave of the hand. With the MGC3xxx controller family Microchip offers a true single chip solution for gesture recognition, removing the need of host processing completely. There are many application now, for example, it been used for controlling volume of audio, switching light and you also can see it in PC/PC Peripheral 3D TouchPad.

Haptics Technology

As designers increasingly look to touch sensing as the primary user interface, haptics provide feedback that enhances the design and usabilit. To give users mechanical feedback, Microchip offer turnkey products incorporating Immersion’s Technology including their Haptic Effects Libraries. Microchip's Haptic technology, or haptics, provides tactile feedback to the user by applying forces or vibrations. It can not only restore the mechanical feel, improve user experience, but also provide more realistic experience, reduce distraction and increase safety. Therefore, it is widely used in many areas, including appliances, industrial, automotive and gaming.
