Cypress Semiconductor unveils a new feature for its Gen4 TrueTouch touchscreen controllers that dramatically improves system performance without added cost. Based on Gen4’s patent-pending high-voltage Tx drivers, Tx-Boost extends Gen4’s performance by delivering three times higher signal-to-noise ratio than previously possible. This is accomplished without the use of performance-robbing digital filters or external components. The Tx-Boost feature, now available on all TrueTouch Gen4 devices, uses specialized hardware acceleration to triple the already best-in-class SNR of the Gen4 family. This high SNR enables manufacturers to employ sensor-on-lens with direct lamination to displays and in-cell architectures with flawless performance for the thinnest products in the market.
In addition, Tx-Boost efficiently parallelizes multiple operations in hardware, without burdening the CPU with costly digital filtering. This significantly increases Gen4’s scan speed, making the touchscreen controller even faster. These parallel operations also further improve Gen4’s power consumption by increasing the amount of idle time during each scan period. The Tx-Boost solution is now available on all Gen4 TrueTouch devices.
