Build mobile devices with Wi-Fi and Bluetooth


CSR and PortalPlayer have joined forces to eliminate the inconvenience of wires on personal media players (PMPs) by adding Wi-Fi and Bluetooth connectivity. Through seamless integration between PortalPlayer's PP5022 applications processor family and CSR's UniFi Wi-Fi and BlueCore Bluetooth ICs, system OEMs can deliver wire-free media players. Wi-Fi will simplify the synchronisation of media players with a PC as well as opening up new ways to download and stream content from the Internet. Bluetooth will enable wireless stereo headset connectivity.

CSR’s UniFi-1 Portable supports 802.11a/b/g Wi-Fi and has been designed specifically to minimize coexistence design issues. In addition to functioning properly in close proximity to a Bluetooth radio, UniFi provides multi-mode 802.11a/b/ or g operation, low power consumption, and built-in antenna diversity processing for extended speed and range. CSR’s BlueCore4-ROM implements Bluetooth v2.0+EDR (Enhanced Data Rate). In addition to delivering data rates up to three times faster than products using previous versions of Bluetooth, EDR Bluetooth also has a similar effect on power consumption with BlueCore4 powered products lasting up to 3 times longer.

PortalPlayer's PP5022 system-on-chip utilizes dual 32-bit ARM7 microprocessor cores and extensive firmware to provide scaleable performance and maximize battery life for PMPs. The efficient design supports leading audio encoders, digital rights management technologies, and multiple I/O and networking connectivity enhancements.
