Cypress Produces its Gen4 Family Earlier than Expected

Cypress Semiconductor’s Gen4 controller, delivers the best performance in all categories including the world’s best signal-to-noise ratio (SNR) and unparalleled performance in the presence of all noise sources, is now in production ahead of schedule.

With the lowest active power consumption, the Gen4 family assisting manufacturers in solving the ever increasing battery life issues common to handheld touchscreen devices.

The Gen4 family was designed to deliver the world’s highest SNR in real world applications. It is the first and only touchscreen IC that delivers built-in 10V Tx to drive the touch panel at 10V. Since SNR is directly proportional to the voltage at which the panel is driven, this feature allows Cypress to offer nearly four times the SNR of the next closest competitor.

Gen4’s patent-pending Display Armor™ offers unprecedented immunity to noise from every type of display, even noisy low-cost displays such as ACVCOM LCDs because it raises the SNR bar as the first touchscreen device family to completely eliminate display noise in hardware. This allows touchscreen designers to make their products thinner by removing the air gap between the display and the sensor, and also less expensive by removing the shield layer in the sensor. Display Armor allows Gen4 to operate seamlessly with direct lamination, on-cell and in-cell stackups, regardless of the display chemistry.

In addition to unmatched noise performance, Gen4 offers the world’s lowest active power consumption of 2 mW, and a deep sleep mode that only draws 1.8 uW with wake-up via address match on the COM port. Gen4 gives OEMs another tool to help solve this problem of short-life battery. The Gen4 product family also boasts the industry’s fastest refresh rate of 400Hz, and has the unique ability to scan a capacitive touch panel at 1,000 Hz. This level of performance is enabled by the 32-bit ARM® Cortex™ core at the heart of the Gen4 products. The Gen4 family enables unlimited touch performance, while providing the industry’s best accuracy and linearity of 0.2 mm.
