Cypress Introduces Reference Design Kit For Low-Power Wireless Mice And Keyboards


June 13, 2006

Kit Simplifies Development with Robust, 2.4-GHz WirelessUSB™ LP Radio System-on-Chip

SAN JOSE, Calif., - Cypress Semiconductor Corp. (NYSE: CY) today introduced a reference design kit that simplifies development of wireless mice and keyboards. The WirelessUSB™ LP Reference Design Kit (RDK) provides designers with illustrative implementations of Cypress’s low-power WirelessUSB LP 2.4-GHz radio system-on-chip in a mouse, keyboard and bridge system. The CY4636 RDK, which includes the WirelessUSB protocol for best-in-class interference immunity, can also be used for development of additional Human Interface Devices (HIDs) such as presenter tools, remote controls, and PC game pads.

The WirelessUSB LP RDK includes a compact wireless mouse, a feature-rich wireless keyboard, and a small form-factor bridge, each enabled utilizing Cypress’s enCoRe™ II family of flash MCUs. To further streamline the development process, it also offers kit documentation, hardware schematics, bill of materials, development tools, and flexible firmware for adding customized features. Manufacturers can easily copy the reference designs exactly, and only need to add enclosures to produce ready-to-ship devices. The designs do not require any special USB drivers.

“The RDK’s extremely low-component wireless keyboard, mouse, and dongle are enabled by utilizing Cypress’s enCoRe II family of flash MCUs and WirelessUSB LP,” said Marcus Kramer, director of Cypress’s HID Business Unit. “It makes it easier than ever to quickly produce low cost and low power plug-and-play wireless devices that take full-advantage of the extremely robust WirelessUSB LP 2.4-GHz solution.”

The CY4636 WirelessUSB LP RDK includes all of the following items:
• WirelessUSB Keyboard - 101 keys with buttons to support multimedia and shortcut keys. Uses Cypress WirelessUSB LP (CYRF6936) and Wireless enCoRe II (CY7C60123) flash MCU
• WirelessUSB Mouse - Three-button, ergonomic mouse with Avago 3040 low-power optical sensor. Uses Cypress WirelessUSB LP (CYRF6936) and Wireless enCoRe II (CY7C60323) flash MCU
• WirelessUSB Bridge - Simple and small form-factor bridge. Uses WirelessUSB LP (CYRF6936) and enCoRe II (CY7C63803) USB flash MCU
• WirelessUSB LP RDK CD-ROM - Provides kit documentation, hardware schematics, bill of materials, development tools, tutorials, and firmware for Wireless Keyboard and Mouse development.

About WirelessUSB LP
Cypress’s WirelessUSB LP offers an unparalleled feature set to enable superior interference immunity, low bill-of-materials (BOM) costs, higher data rate applications, and faster time-to-market for keyboards, mice, gaming devices, presenter tools, and remotes, as well as other simple, multi-point-to-point wireless applications. Featuring a highly integrated radio transceiver plus digital baseband on a single chip, it operates between 1.8 and 3.6 volts, using advanced power-saving techniques to extend battery life in devices such as wireless mice. WirelessUSB LP uses Cypress’s patented frequency agile Direct Sequence Spread Spectrum (DSSS) technology to offer best-in-class interference immunity for a 2.4-GHz radio system. This combination of low power consumption, interference immunity and low cost make it ideal for wireless HID applications.
