21ic News Cypress Semiconductor Corp. has introduced a single-chip solution that integrates radio frequency and touch sensing circuitry to support wireless mice, touchpads, remote controls, presenter tools and other human interface devices (HID) . The new PRoCTM-UI (Programmable On-Chip RF-User Interface) solution combines 2.4-GHz proprietary WirelessUSBTM-NL RF with Cypress CapSense® and TrueTouch® capacitive touch technology to support wireless The user interface features of the device, including the gestures supported by the upcoming Windows 8 app. This article refers to the address: http:// In addition, this single-chip solution provides standard HID microcontroller functionality that efficiently combines three chips to reduce BOM cost, board space, power consumption, and multi-chip implementations. Compared to higher reliability. Cypress's CapSense technology has replaced more than 4 billion mechanical buttons, making Cypress the leading supplier of capacitive touch products. CapSense supports a sleek, aesthetic interface that delivers outstanding reliability compared to mechanical buttons. In addition, PRoC-UI features Cypress's industry-leading TrueTouch touchscreen technology, which enables a variety of new HID use cases with multi-finger gesture recognition, including support for new Windows 8 gesture controls. TrueTouch is also tuned to support custom gestures. The CapSense and TrueTouch families include advanced features such as proximity sensing (wake-up devices when the hand is close) and tactile responses (providing tactile feedback to the user). The PRoC-UI achieves excellent reception sensitivity of up to -87 dBm at a transmission rate of 1 Mbps, and higher sensitivity not only extends the operating range (up to 30 meters), but also receives low-power transmission signals. The device's low operating and standby currents extend battery life. In addition, it delivers outstanding performance in the presence of other common 2.4-GHz interference sources such as WiFi, Bluetooth, cordless phones and microwaves. Jayant Somani, senior director of global marketing at Cypress's Data Communications Business Unit, said: "We are seeing a new range of emerging applications and use cases that combine touch technology with wireless capabilities. Cypress has already marketed it. The leading user interface and wireless technology are perfectly integrated to meet these needs. The PRoC-UI solution saves money by achieving higher integration, shorter design time, lower power consumption and smaller size. Cost. More importantly, it enables our customers to differentiate their products in a highly competitive environment." PRoC-UI supports Cypress's AgileHIDTM protocol, allowing existing WirelessUSB-NL customers to quickly launch designs with minimal effort. Customers who have designed with WirelessUSB-NL can continue to use the original dongle on the new PRoC-UI touch product. In addition, PRoC-UI comes with free software for implementing the final product customization. Availability PRoC-UI is sampling now in 40-QFN and 68-QFN packages and is expected to begin mass production in January 2013.
