mTouch Sensing solutions fit primarily into what are called Human Interface products. Human Interface products take inputs from the user via keypads, switch and buttons and provide output that is visible or audible to the user. Many also include various types of communication features like …

6. First, lets take a look at Microchip’s lowest power touch sensing solutions for keys and sliders.

7. Capacitive Touch Principle
Introduction of a finger produces a parallel capacitance (CF) CF CP
PCB
Front Panel
Sensor
Ground Trace Cs
Before we move further, lets quickly review the capacitive touch principle so we understand what features are built into the MCU to detect capacitive touch. As you can see in the figure, a human finger touch adds a second capacitance in parallel with the pad’s capacitance. The human body creates strings of capacitors between the board and the ground. So, when a user creates a capacitance by moving his or her hand into close proximity of another conductor, it creates a capacitance essentially coupled to ground. The MCU uses on-chip peripherals to detect and measure that change in capacitance.
CP is the Parasitic capacitance
CF is the Finger capacitance
Cs is the total Sensor capacitance
Sensor Capacitance (CS) = CP + CF

8. One-Stop Shop for Touch Sensing
Industry’s broadest portfolio
Turn Key solutions
Micro based solutions
Industry’s lowest power touch solution
High robustness to noise & low emissions
Works through most surfaces – glass, plastic, metal (stainless steel, aluminum)
Microchip was one of the first suppliers to develop touch-sensing solutions in the industry and as a result we’ve built up one of the broadest touch sensing portfolios in the industry. What that means for your customers is that we can provide touch solutions from just a few buttons (1-4) all the way up to solutions including many keys and sliders plus segmented or graphical LCD displays, RF stacks, USB communication etc; All on a single chip.
PIC MCUs featuring mTouch technology also leverage Microchip’s nanoWatt and nanoWatt XLP technologies delivering the lowest power touch sensing solutions in the industry.
The firmware enabling mtouch™ sensing technology is downloadable free of charge as a software library. We also provide the source code behind the library putting your customers in complete control of their design.
Another facet of Microchip’s mTouch sensing solutions is their ability to work through both plastic and metallic design finishes. Now customers don’t have to compromise on the stylish, modern and elegant looking user interface. Whether your customer’s using brushed metal or stainless steel surface there is a solution. In many cases such surfaces are desirable to enable water-proof performance or to aid disabled people (using braille).

9. Low Power Touch Sensing
Increase your Battery Life
Lower current in standby mode
<5 µA touch-sensing with PIC® MCUs
eXtreme Low Power (XLP) technology on many MCUs
Sleep current down to 9 nA
Active current down to 30 µA/MHz
Real-Time Clock current down to 400 nA
Low power consumption increases the battery life and for Mains-powered applications it may lower current in stand by mode.
Touch sensing applications often implement a capacitive sensor that wakes up the entire application when the user is in close proximity. This requires the MCU to wake up periodically from Sleep, scan a capacitive sensing channel, decode the data and decide whether to remain awake or go back to sleep. For this reason it is important for the MCU to consume low amounts of current in both sleep and active modes. In addition, it is also important that the on-chip real-time clock peripherals consume low power.
Many XLP based PIC MCUs may also be used in touch applications. Sleep currents down to 9nA, active currents down to 30uA/MHz and low RTC currents of 400nA make PIC MCU based touch applications the lowest power in the industry.

10. General Guidelines RightTouch® mTouch™ Technology
No firmware experience
Analog design engineer
No system integration value
Lowest device cost
Not low power focused
Just want touch function
3 to 14 Channels
Simple/Basic implementation
mTouch™ Technology
Firmware experience
Digital design engineer
Wants to integrate other functions
Lowest system cost
Low power is important
Want to customize
Larger key count
Complex interactions between proximity, sliders and keys
We can look at the comparisons between the product to help us make the determination of which way a customer may want to go between the two. If you have a customer that has a handheld device that needs to have wireless capability, it makes more sense to go with mTouch because there’s more firmware flexibility and low power will probably be important to the customer since it’s a handheld application.

Touch may be implemented from virtually any PIC MCU:
On the low-end PIC10 and PIC12 families may be used for simpler applications requiring only touch and few othr functions.
PIC16 8-bit MCUs step up the performance a bit and integrate peripherals like PWM and LCD while maintaining low-cost and low power.
PIC18 8-bit MCU family improves performance and supports larger segmented LCD, plus adds USB 2.0, 12-bit ADC and other peripherals.
PIC24 16-bit MCU delivers 32MHz performance, supports even larger segmented LCD screens and adds peripherals such as graphical TFT/STN displays, high-speed analog, USB OTG and up to 256KB of Flash on a single chip. Even at this performance class of device, sleep currents are as low as 20nA.
PIC32 adds ethernet capabilties
Overall, PIC MCUs support up to 32 cap touch channels on a single chip. Please note that a single cap touch channel on a PIC MCU does not always equate to a single cap touch key implemented in the system. Matrixing techniques can be used to implement much larger numbers of keys.
Lets look at the kinds of implementation that each of the families enables.

17. Metal over Cap
First, lets take a look at Microchip’s lowest power touch sensing solutions for keys and sliders.

18. Metal-Over-Cap Technology
In addition to plastic and glass, sense through stainless steel, aluminum, and more
Completely waterproof
Through thick gloves
Up to now, Cap touch was suitable only for Plastic or Glass. With Metal over Cap technology it’s now possible through a Metal panel as well.
Where cap touch applications may be made water resistant, metal over call can be completely waterproof!
Metal over cap is also possible through thick gloves which is an important feature when considering outdoor or industrial applications.
… and it still supports the important features of the rest of our cap touch solutions like low power, low cost, and a highly integrated solution with no external components. 18

Appliance manufacturers like metal over cap for stainless steel finishes and waterproof features.
It also provides more of a tactile feel to the user because they must press on it for it to work as opposed to merely touching the button or slider.
Since it’s completely waterproof it may be cleaned without triggering keys.
For consumer applications, allowing Braille is a key factor. The user can feel for the marking without triggering the keys. Once the right key is found they can press it to trigger. 19

How does Metal Over Cap work?
Instead of measuring the change in capacitance added by the user’s finger, metal over cap measures the change in capacitance created by the change in distance between the panel and the sensor. Since the capacitance may be changed by changing the distance only a few microns a metal cover may be used. e e A r =

21. Simple Mechanical Construction
The only difference is the introduction of a spacer layer to allow the deflection of the front panel
It needs to be non deformable
Thickness must be between 50um and 150 µm
The most common materials are Glue, FR4 or Mylar
The Front panel can be metal, plastic with metal flash/coating…
The mechanical construction of an application utilizing Metal over Cap technology is quite simple. 3M products like 7956MPL or 9185MP can be used to glue the spacer layer together with the metal front panel and the PCB.

Touch screens are user-friendly input devices that are quickly becoming the standard for everyday human-machine interface on a variety of products including industrial machines, grocery store check-out lines, cell phones and personal media players.
It is important to understand that there is no single perfect touch technology that fits every design and application – all have different strengths and weaknesses. This chart highlights the main topics for consideration when choosing a touch technology.
Resistive technology, used primarily for larger screen touch applications, is the market volume leader by far, with >80% of all touch designs. The main advantages of resistive touch sensors are low cost, easy integration and acceptance of finger, stylus or gloved input.
Popular consumer applications that use multi-touch and gestures have fueled an increased demand for projected capacitive touch sensors. In addition to enabling multi-touch, projected capacitive offers a durable glass front that also provides superior optics.

Pictured here are some of the more typical Analog Resistive touch applications. You can see that the screen sizes for these applications tend to be a bit larger. 48 48

49. How Analog Resistive Works
Two layers of Indium Tin Oxide (ITO) on polyester separated by a spacer layer
When touched, top (flex) layer moves past spacer layer and contacts bottom (stable) layer
Point of contact creates voltage divider in the X and Y directions
Resistive 4, 5, and 8-wire touch sensors consist of two facing conductive layers, held in physical separation from each other. The main differences between the various implementation is the resolution of the touch screen. In Analog Resistive Touch applications a touch causes the top layer to move and make electrical contact with the bottom layer. Touch position measurements are typically made by applying a linear voltage gradient across a layer or axis of the touch sensor. The touch position voltage for the axis can be measured using the opposing layer.
Options to support gestures are currently under review for future product releases
