Touch and Gesture
Why Capacitive Touch?
From your customers perspective, the user interface is the product.
Innovative, modern and attractive. In short, high-selling products all have one
thing in common—they all have a user-friendly touch interface.
Adding touch to your product adds value to your product. Interfaces with
mechanical push buttons have several moving parts, significantly decreasing
reliability. Mechanical buttons also require complex design and assembly as well
as a major investment in tools.
Why Touch Now?
You’re ready for touch on a global scale. Touch has matured to
include water-tolerant, noise-robust and low-power solutions.
Next generations will see touch as a requirement. The time is
now don’t miss the touch train.
Why Touch With Microchip?
With over a decade of experience in automotive touch, Micro-
chip is the leading provider of robust touch solutions. Further-
more, we focus on our touch tool chain to ensure your touch
journey is as short as possible, minimizing your time to produc-
tion. Microchip is also aware that you operate globally. We will
provide native language support at your design locations and at
your or your CM’s production facilities. Local support on global
scale—your risk-mitigating benefit.
Turnkey Touch Products
Turnkey touch controllers provide the fastest and easiest way to
go from mechanical buttons to modern touch buttons or displays
with touch. Our turnkey touch products include ready to use
controllers for touch buttons, sliders and wheels as well as con-
trollers for touch pads, touch screens and proximity solutions for
consumer, industrial and automotive applications. No program-
ming experience is needed, just connect the sensor and turn on
power. All controllers communicate to the host via standard serial
interfaces, such as I
2
C, SPI or USB as well as GPIO.
Microcontroller With Touch Integration
Microchip offers a wide range of 8-, 16- and 32-bit devices with
our PIC
®
, AVR
®
and SAM MCU and MPU series. All of these
platforms enhance touch with dedicated on-chip touch Core
Independent Peripherals (CIPs).
Microchip’s touch library is supported by all of Microchip’s code
configurators, enabling you to easily access Microchip’s de-
cades of experience in capacitive-touch design. To save code
space, enhance usability and speed up the development of your
touch project, Microchip provides the touch library individually
tailored to your use case via MPLAB
®
Code Configurator and
Atmel START.
Implementing touch on an MCU has never been easier!

Microchip’s Performance Advantage
Regardless if you chose a turnkey touch product or a touch library to integrate with your code—you will benefit from Microchip’s
performance in touch.
Noise Robustness
Noise, also known as conducted noise, is a com-
mon challenge for touch implementations. Microchip
provides state-of-the-art software and hardware
filters to overcome noise - meaning to enable touch
buttons to work through the noise. Noise-avoidance
technologies, such as frequency hopping are used.
•
High Signal-to-Noise Ratio (SNR)
•
IEC61000, EFT and BCI tested, 15V+ Rms
Water-tolerant touch is a key feature that Microchip
integrated into turnkey and MCU-based touch solu-
tions. Users expect their touch interfaces to work in
a range of conditions (including wet surfaces) without
the need to clean their hands or wipe them dry every
time they use their devices.
High Button Count Support –
Mutual Touch Sensing
Water-Tolerant Touch
Microchip has refined and enhanced the method to
scan a large number of buttons as a matrix. Mutual
touch enables costs savings in many aspects:
•
Reduced amount of feeding lines to slim connect-
ing (flexPCB) tails
•
Reduces pin count required for touch to enable
cost-efficient small-footprint parts
•
Dramatically reduced development time by
Microchip’s unique inherent feeding line length
compensation
Functional safety, Failure Modes and Effects Analysis
(FMEA) is a market driver for touch. For the market
of appliances, Microchip offers products (turnkey
and libraries) certified according to IEC/UL 60730
Safety Class-B standards. Certificates are published
on Microchip’s website at
www.microchip.com/touch.
Safety-Certified Touch Sensing
Touch on Metal – Waterproof Touch
Microchip offers Metal-over-Capacitive (MoC)
technology enabling:
•
Metal surfaces, stainless steel or aluminum
•
Sense through any thickness of glove
•
Waterproof designs
•
Braille-enabled interfaces
Automotive Touch
Metal-over-capacitive technology is compatible with all turnkey
and MCU-based touch products.
Low(est) Power
Microchip is the leading provider for automotive touch
- screens, buttons, touch pads, kick sensor - inside
and outside the car. Our solutions are tailored to meet
the noise robustness and emission requirements. Our
experience in functional safety applications combined
with automotive grade hardware ensures to enable
your designs.
Requirements for low power are not limited to
wearable devices—it’s a recurring requirement in all
markets including automotive. Dedicated hardware on
PIC, AVR and SAM devices enable the lowest power
touch with multiple capacitive sensing below 5 μA.
