Cypress Semiconductor Corp. has introduced its next-generation Programmable Radio-System-on-a-Chip (PRoC). The single-chip PRoC LP integrates WirelessUSB LP 2.4GHz transceiver with the low-cost enCoRe II 8bit flash MCU.

The chip promises simplified coding and board layout to cut design time and reduce board space requirements for innovative, small form-factor wireless human interface devices (HIDs) such as mice, presenter tools and RF remote controls.

Reduced BOM
The company said PRoC LP offers a reduced component count versus competing solutions, reducing the overall BOM for HID applications. The device uses patented frequency agile DSSS technology to offer interference immunity for wireless systems operating in the worldwide 2.4GHz ISM band, making it suitable for crowded RF environments.

"PRoC LP's pairing of the lower power consumption and superior interference immunity of WirelessUSB LP with the enCoRe II Flash MCU makes it the perfect solution for wireless HID applications," said Norm Taffe, executive VP, computation and consumer division at Cypress.

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.

Longer battery life
PRoC LP delivers up to a 1Mbps data-rate, -97dBm receive sensitivity, and functions at 0.87mA average current to extend battery life in HID applications to one year.

PRoC LP also incorporates the user-friendly KISSBind feature, which enables a user to intuitively link a wireless peripheral to the desired host by simply bringing them in very close proximity with one another, thus lowering customer support calls.

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 each for 100,000 units.
