CSR's BlueCore5-FM chip is the first product from the BlueMedia roadmap, incorporating a sensitive FM radio receiver in a small, single-chip design. It is the first Class 1 Bluetooth single-chip solution to meet the Bluetooth v.2.0 + EDR spec, according to the company.
More information on Bluetooth EDR is available at Taking a walk inside Bluetooth EDR.
Available in 4x4 mm WLCSP or 6x6 mm VFBGA packages, BlueCore5-FM offers connectivity of up to 3 Mb/s and output power of +10 dBM. This allows the device to easily cover the 100 m range required for a Class 1 Bluetooth radio without the need for an external amplifierall within a PCB footprint of only 39.2 mm2.
BlueCore5-FM was designed specifically for mobile handsets. It consists of an FM receiver operating at the thermal noise floor of -111 dBM and CSR's enhanced data rate (EDR) BlueCore radio.
As a single-chip solution, BlueCore5-FM offers double the functionality without taking up valuable space on the circuit board while also reducing the analog component count and total BOM compared to the dual-chip alternative.
Interference free, BlueCore5-FM allows the Bluetooth and FM radios to work independently of each other or in tandem, for example, streaming FM radio from a handset over a Bluetooth connection to a pair of stereo headphones.
"Bluetooth technology has evolved significantly in terms of power consumption and the reduction of interference with other radios," said Matthew Philips, Senior VP for the company's Mobile Handset Connectivity Strategic Business Unit. "BlueCore5-FM demonstrates that we can now provide Class 1 connectivity for handheld devices without compromising on battery life or bill of materials (BOM)."
