Yota Devices today announced its "always-on" premium Android YotaPhone is now in production with both displays powered by TrueTouch® Gen5 capacitive touchscreen controllers from Cypress Semiconductor Corp. Cypress's TMA568 controller delivers advanced multi-touch functionality to the AMOLED display, while the TMA545 controls YotaPhone's second electronic paper display.
Officially launched at a Yota Devices' event in Moscow today, the next generation YotaPhone leverages Gen5 by adding the market's most accurate gloved finger tracking and most robust water tolerance to both displays, while also contributing to the phone's thin design and long battery life.

YotaPhone's always-on display gives users continual access to maps, social media content, alerts and other information people want for extended periods of time, without having to wake up their phone. The electronic paper display leverages Gen5's low power consumption to preserve the smartphone's battery life. The TMA568 controller supports an ultra-thin on-cell stackup for the front screen, made possible by the Gen5 family's unmatched immunity to electrical noise from displays.
"We introduced the YotaPhone dual-screen usage model with a vision to revolutionize how people use their smartphones," said Yota Devices CEO Vladislav Martynov. "The launch of the next generation YotaPhone takes the 'always-on' smartphone concept to another level, with industry-leading touchscreen performance enabled by Cypress's TrueTouch Gen5 solutions."
"The launch of the next generation dual-screen YotaPhone is yet another example of the world's most innovative handset makers selecting our TrueTouch Gen5 family for their premium models," said Hassane El-Khoury, executive vice president of the Programmable Systems Division at Cypress. "This new YotaPhone shows both the versatility and feature rich performance Gen5 delivers. We are constantly driving to help our customers improve the user experience of their touchscreens, as demonstrated with our announcement of additional advanced features to the Gen5 TMA568 controller."
Cypress also announced that its TrueTouch Gen5 TMA568 controller now supports gloved-finger tracking, 1-mm passive stylus, and a hover feature that enables touchscreens to anticipate the touch of a finger and enlarge content to make it easier to find and select objects.
Electronic noise from displays and after-market chargers can disrupt a touchscreen's ability to operate properly. The TrueTouch Gen5 family's ChargerArmor™ feature delivers unprecedented 40 volt peak-to-peak (Vpp) charger noise immunity measured from 1 to 500 kHz with an ultra-thin 0.5-mm cover lens and a finger-size up to 22 mm -- the most stringent specifications used to measure any touchscreen controller. No competing controllers deliver noise immunity over 15 Vpp under these conditions.
With Cypress's unique and patented DualSense™ technology to execute both self-capacitance and mutual-capacitance measurements in the same device, the Gen5 family offers the industry's best waterproofing for seamless performance in real-world conditions, including the presence of rain, condensation, or sweat. By combining this powerful architecture with an industry leading 32-bit ARM® Cortex™ M-Core processor that is known for high-efficiency MIPS/mW, Gen5 controllers boast 120-Hz refresh rates and low power consumption. Gen5 controllers drive the touchscreen at 10V and at high frequency with narrow-band, single-pass scanning and advanced hardware DSP filtering.
