Cypress Semiconductor TrueTouch provides touchscreen for low-cost mobile phones

By Telecomlead Team: Cypress Semiconductor unveiled
TMA140 TrueTouch controllers for lower-cost mobile phones. The new family
offers touchscreen multi-finger control support, Signal-to-Noise Ratio (SNR)
and Cypress’s patent-pending Charger Armor feature for screens of up to five


Charger Armor feature uses adaptive frequency hopping and
other techniques to prevent false touches due to excessive noise from a


Cypress‘s TrueTouch technology provides
noise immunity, highest signal to noise ratio (SNR), fastest refresh rates,
lowest power consumption, accuracy and linearity.


The new TMA140 family delivers high performance
multi-touch capabilities on a feature phone budget. The low power family offers
better than 0.5-mm accuracy, delivers gesture capability and works flawlessly
with Android.


We also have announced the SLIM sensor that enables true
multi-touch into lower-cost phones via a single-layer sensor. TrueTouch now offers
the industry’s best solution for the hottest new smartphones (our Gen4
controllers) as well as lower cost features phones, and everything in between,” said John
Carey, director of TrueTouch Marketing at Cypress.


TMA140 works with SLIM, Cypress’s Single Layer
Independent Multi-touch sensor. SLIM is a true single-substrate, single layer
ITO touchscreen sensor and reduces the thickness of the sensor module. SLIM
requires no additional insulation layers or bridges and reduces the cost of
traditional multi-touch sensors by roughly 40 percent.


TMA140 and SLIM create the world’s lowest cost
multi-touch solution in the market, making multi-touch affordable for feature
phones. The TMA140 sensor family is now in mass production and comes in 36-pin
or 48-pin QFN packages.


Cypress recently announced  that
BICOM, DSP solutions providers for telecommunications and consumer electronics
products, selected Cypress PSoC programmable system-on-chip for its playGo USB
premium wireless audio solution.
