Cypress adds support for single-layer sensors and gloved-finger tracking to TrueTouch Gen4X touchscreen family

Cypress Semiconductor has said that its TrueTouch Gen4X touchscreen controller family is now able to support single-layer multi-touch sensors which has helped to lower manufacturing costs but had no impact on performance. The Gen4X TMA445 controller enables thin form factors by leveraging Cypress’s Single-Layer Independent Multi-touch (SLIM) sensor structures. The controller also adds support for Cypress’s industry-leading tracking of multiple fingers in gloves.

The TrueTouch Gen4X TMA445 controller delivers best-in-class accuracy and linearity for fingers of different sizes and gloves of various materials and thicknesses, including ski gloves. In addition, it automatically switches between glove and finger tracking without requiring the user to switch settings. Gen4X controllers provide industry-leading water tolerance and best-in-class immunity to electronic noise from aftermarket chargers and displays.

“Gen4X with SLIM delivers what we believe is the industry’s best single-layer sensor performance,” said Yi Hang Wang, Director of TrueTouch Marketing for Cypress. “SLIM helps our customers create thin mobile devices at lower costs. This combination has helped the family quickly gain popularity in China and other cost-competitive markets. With the addition of our multi-finger tracking for users wearing gloves, Gen4X is upgrading the touchscreen user experience for mobile devices.”

Cypress’s TrueTouch Gen4X family delivers immunity to charger noise of up to 35V peak-to-peak (Vpp) from 1-500 kHz, with a 0.5-mm cover lens and a 9-mm-wide finger. With Cypress’s unique and patented DualSense technology to execute both self-capacitance and mutual-capacitance measurements in the same device, the family offers the industry’s best water rejection and wet finger tracking for seamless performance in real-world conditions, including the presence of rain, condensation, or sweat. The TrueTouch portfolio’s unique features are backed by an industry-leading portfolio of more than 100 capacitive touch sensing patents.

The Gen4X family is based on a 32-bit ARM Cortex M-Core processor that is known for high-efficiency MIPS/mW. The TMA445 controller averages low power consumption of 12 mW in active mode and 15 uW in deep-sleep mode.
