Cypress Semiconductor's PRoC LP integrates the company's WirelessUSB LP 2.4-GHz transceiver with its low-cost enCoRe II 8-bit Flash microcontroller for reprogrammabiity.
The device uses patented frequency agile Direct Sequence Spread Spectrum (DSSS) technology to offer interference immunity for wireless systems operating in the worldwide 2.4-GHz ISM band, making it ideal for crowded RF environments.
Component count is reduced by operating off a single crystal and by integrating voltage converters and passives, thus lowering system cost and board layout complexity. PRoC LP delivers up to a 1 Mbps data-rate, -97 dBm receive sensitivity, and functions at 0.87 mA average current to extend battery life to one year.
The PRoC LP simplifies coding and board layout to cut design time and reduce board space requirements for small form-factor wireless Human Interface Devices (HID) such as mice, presenter tools and RF remote controls.
PRoC LP offers a reduced component count versus competing solutions, reducing the overall bill of materials (BOM) for HID applications.
PRoC LP is available in a compact, 40-pin QFN package. The in-system reprogrammable Flash-based MCU enables last-minute firmware changes and eliminates the need for external EEPROM to store binding parameters.
Cypress is currently sampling the PRoC LP CYRF69103 for mice and other peripherals and the PRoC LP CYRF69213 for USB bridges/dongles, both in 40-pin QFN packages. Full production quantities of both will be available in February 2007. Pricing starts at under $2.00 each in 100,000-unit quantity.
