The new PRoC-UI (Programmable Radio-on-Chip – User Interface) one-chip solution from Cypress Semiconductor supposedly works on the combined prowess of the low-power 2.4-GHz proprietary WirelessUSB-NL Radio-on-a-Chip blended with Cypress’s CapSense and TrueTouch capacitive touch technologies.
The solution integrates a wireless radio with touch-sensing circuitry for wireless mice, trackpads, remote controls, presenter tools, and other Human Interface Devices (HIDs). These advanced features should make wireless devices carry UI functionality along with button and slider replacement, and Windows 8 gesture support.
Jayant Somani, senior director of worldwide marketing for Cypress’s Data Communication Division commented, “We are seeing an emerging class of applications and use cases that combine touch with wireless functionality. Cypress has integrated its market-leading user interface and wireless technologies to respond to this need. The PRoC-UI solution delivers cost savings through integration, shorter design times, lower power, and smaller form factor. Perhaps more importantly, it allows our customers to differentiate their products in a highly competitive space.”
By merging the functionalities of system MCU, touch controller and radio, PRoC-UI can bring down BOM cost, board space and power and is stated to be more reliable than multi-chip implementations.
A client of Cypress acknowledged that PRoC-UI not only integrates touch and wireless into a single device, but also offers easy integration with external components. Moreover, Cypress’s excellent customer support makes designing touch-based wireless HID products simpler and faster.
Some of the notable features of the PRoC-UI are: -87 dBm (News - Alert) receive sensitivity at 1 Mbps; longer range operations and lower-power transmit signals; low active and standby currents result in longer battery life; 2.4-GHz interference supports superior performance from sources like Wi-Fi, Bluetooth, cordless phones, and microwaves; and more.
