Cypress Introduces Low-Power Programmable Radio-System-on-a-Chip Integrating 2.4-GHz Transceiver And Flash Microcontroller

Cypress Semiconductor Corp. introduced its next-generation Programmable Radio-System-on-a-Chip. The single-chip PRoC™ LP integrates the proven, robust WirelessUSB™ LP 2.4-GHz transceiver with the 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.

Single-Chip PRoC™ LP Delivers Unprecedented Board Space Savings and Reduced Design Time

PRoC LP offers a reduced component count versus competing solutions, reducing the overall bill of materials (BOM) for HID applications. The device uses 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 environme

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. 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
