Chip combines a 2.4-GHz, wireless radio, and capacitive touch
Suitable for wireless mice, trackpads, remote controls, presenter tools, and other Human Interface Devices (HIDs), the PRoC-UI (programmable radio-on-a-chip–user interface) solution combines 2.4-GHz proprietary WirelessUSB-NL Radio with the company’s CapSense and TrueTouch capacitive touch technologies. This combination enables user interface functionality in wireless devices, including gestures supported by the upcoming Windows 8 applications.
The one-chip solution also offers standard HID microcontroller functionality, effectively combining three chips into one to save BOM cost, board space, and power, while increasing reliability compared with multi-chip implementations. PRoC-UI boasts an impressive –87 dBm receive sensitivity at 1 Mbit/s. The sensitivity enables longer range (up to 30 m) operation and allows for lower-power transmit signals.
The device features low active and standby currents, which enable longer battery life. It also offers superior performance in the presence of 2.4-GHz interference from common sources such as WiFi, Bluetooth, cordless phones, and microwaves. The solution supports the company’s AgileHID protocol that allows existing WirelessUSB-NL customers to get started quickly on their designs without any additional effort. The solution is available in 40-QFN and 68-QFN packages. (Contact company for pricing — samples, now; prd qty, Jan 2013)
