Cypress Semiconductor Corp. (NASDAQ:CY) the market leader in
touch-sensing, today introduced the PSoC 3® CapSense® Plus
capacitive touch-sensing solution for buttons, sliders, touchpads,
and proximity sensing. It’s the industry’s best capacitive-sensing
solution that can also perform general system control functions. To
accomplish this task, the new product combines two premier Cypress
product offerings, the PSoC 3 programmable system-on-chip and the
industry-leading CapSense capacitive touch control technology.
PSoC 3 CapSense Plus lowers system design cost and eases the
design process with Cypress’s revolutionary, patent-pending
SmartSense™ auto-tuning algorithm, which eliminates the requirement
for system tuning. SmartSense enables automatic tuning of more than
10 parameters to achieve optimal touch sensing performance. The
graphical CapSense software module in Cypress’s PSoC Creator™ IDE
makes it easy for designers to define combinations of buttons,
sliders, touch pads and proximity-sensing capacitive sensors, and
offers real-time feedback of parameters such as signal-to-noise
ratio (SNR), finger threshold, noise threshold, and more.
The new PSoC 3 CapSense Plus devices offer up to 62 General
Purpose I/O (GPIO) pins—all of which can handle CapSense
signals—enabling the industry’s largest number of capacitive
sensing elements in a single chip. In addition, the new solution
provides Cypress’s legendary noise immunity that ensures robust
operation in the presence of noise from a variety of sources. More
information on the new solution is available at
www.cypress.com/go/psocpluscapsense.
In addition, an informative web-based module entitled “Upgrade
your Capacitive Touch-Sensing Designs” is available at
http://www.eetimes.com/electrical-engineers/education-training/courses/4229293/Upgrade-your-Capacitive-Touch-Sensing-Designs-.
Cypress is offering the CY8CKIT-031 PSoC CapSense Expansion
Board Kit to speed designs with the new solution. The CY8CKIT-031
includes both button and slider modules, three separate overlays
for prototyping, and a resource CD with example projects and
application notes. The new kit’s adapter board allows engineers to
plug in existing CapSense modules into the CY8CKIT-001 PSoC
Development Kit or the CY8CKIT-030 PSoC 3 Development Kit, giving
engineers access to the complete PSoC 3 ecosystem to create
powerful, customized designs, and ease customers’ ability to re-use
CapSense designs within the PSoC 3 environment. The CapSense
modules kits include the CY3280-BSM Simple Button Module Kit, the
CY3280-SRM Radial Slider Module Kit, the CY3280-SLM Linear Slider
Module Kit, and the CY3280-BMM Matrix Button Module Kit. For
customer who already have these module kits, they are eligible for
a 50 percent discount when purchasing the new CY8CKIT-031kit.

Today, engineers design capacitive touch user interfaces
separately from the central system control function. In most cases,
a ribbon cable runs from the user interface controller to the
system controller to convey user inputs. This design method
requires multiple components, uses more power, and complicates the
system design. Cypress has solved this problem with PSoC 3 CapSense
Plus. Designers now have the ability to integrate both the system
and user interface control in one chip, with the added benefit of
SmartSense auto-tuning that speeds both system design and
prototyping/production by optimizing parameters automatically
during the design process.
“Designers recognize Cypress as the leader in capacitive touch
solutions and also appreciate the power and flexibility of the PSoC
3 architecture,” said Gahan Richardson, vice president of PSoC
platform products for Cypress. “We’ve made it easy for designers to
combine these two marquis technologies to simplify the system
design process in many applications.”
The Cypress PSoC 3 architecture, based on a high-performance
8-bit 8051 processor, has unique programmable analog and digital
peripherals that enable capabilities such as motor control,
intelligent power supply and battery management, LCD segment
display, graphics control, as well as audio/voice processing,
communication protocols, and much more. Its integrated 20-bit Delta
Sigma ADC delivers better than 18-bit effective number of bits
(ENOB) performance.
Cypress’s CapSense technology is the industry’s leading solution
for capacitive buttons, sliders and switches. CapSense
touch-sensing solutions have replaced 3.5 billion mechanical
buttons in mobile handsets, laptops, consumer electronics, white
goods, automotive applications, and virtually any system that has a
mechanical button or switch, making Cypress the industry
touch-sensing leader. The CapSense portfolio, the industry's
broadest and most integrated, enhances industrial design and
reliability with the most noise-immune and water tolerant
capacitive touch-sensing interfaces, including proximity sensing
where direct touch is not required. More information is available
