CSR announced the qualification of the world’s first Class 1 Bluetooth single-chip solution. The BlueCore device is part of the company’s 5th generation silicon and is also the first product from the BlueMedia roadmap, incorporating a sensitive FM radio receiver in a small, single-chip design. Available in 4x4mm WLCSP or 6x6mm VFBGA packages, BlueCore5-FM features the highest performance Bluetooth on the market today, offering connectivity of up to 3Mb/s and unrivalled output power of +10 dBM. This allows the device to easily cover the 100m range required for a Class 1 Bluetooth radio without the need for an external amplifier – all within a PCB footprint of only 39.2mm2.
“Bluetooth technology has evolved significantly in terms of power consumption and the reduction of interference with other radios,” explained Spokesman, CSR. “BlueCore5-FM demonstrates that we can now provide Class 1 connectivity for handheld devices without compromising on battery life or bill of materials (BOM).”
BlueCore5-FM has been designed specifically for mobile handsets and 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 whilst also reducing the analogue 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.
Matthew Philips, Senior VP Mobile Handset Connectivity Strategic Business Unit, “It’s no longer simply a question of integrating a number of different functions within a handset. These days it’s about whether designers can implement high-end functionality without blowing the budget on an expensive BOM or wasting valuable PCB space. BlueCore5-FM sets a new benchmark for the industry in terms of both functionality and performance.”
