Cypress Semiconductor's single-chip PRoC LP integrates the robust WirelessUSB LP 2,4-GHz transceiver with the award-winning, enCoRe II 8-bit Flash microcontroller (MCU). PRoC LP simplifies coding and board layout to cut design time and reduce board space requirements for innovative, small form-factor wireless human interface devices (HID) such as mice, presenter tools and RF remote controls.
PRoC LP offers a reduced component count. It uses patented frequency agile Direct Sequence Spread Spectrum (DSSS) technology to offer high interference immunity for wireless systems operating in the 2,4 GHz ISM band.
"By integrating a radio and a Flash MCU, Cypress's PRoC LP enables a component reduction that adds up to significant savings for wireless PC peripherals, where cost is highly important," said Brian O'Rourke, senior analyst in the Converging Markets and Technologies Group at In-Stat. "Many consumers use wireless peripherals in crowded RF environments, which the interference immunity of Cypress's 2,4 GHz WirelessUSB protocol addresses."
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. Component count is further reduced by operating off a single crystal and by integrating voltage converters and passives 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 in HID applications to one year.
