Cypress's PRoC LP™ Programmable Radio-System-on-a-Chip integrates Cypress's proven, robust WirelessUSB™ LP 2.4-GHz transceiver and award-winning, low-cost 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 uses Cypress's patented frequency agile Direct Sequence Spread Spectrum (DSSS) technology to offer best-in-class interference immunity for wireless systems operating in the worldwide 2.4-GHz ISM band, making it ideal for crowded RF environments. The device 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. This highly integrated wireless solution also reduces component count 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 in HID applications to one year.
