Broadcom Launches GPS/FM/Bluetooth Chip

Broadcom Corporation has announced a combined GPS/FM/Bluetooth device — the BCM2075 — designed to provide location based services (LBS) and advanced multimedia in a single chip.

Broadcom Corporation has announced a combined GPS/FM/Bluetooth device — the BCM2075 — designed to provide location based services (LBS) and advanced multimedia in a single chip.

The BCM2075 combo chip integrates four radios (Bluetooth, GPS, and FM receive and transmit). Broadcom’s InConcert collaborative co-existence technology allows these radios to operate simultaneously, and with minimal interference, according to the company. Broadcom will demonstrate this new combo chip solution February 16–19 at the Mobile World Congress in Barcelona, Spain.

The BCM2075 is targeted at portable devices, such as mobile handsets, portable media players (PMPs), and personal navigation devices (PNDs) and is backwards compatible with Broadcom’s BCM2049 combo chip announced last October. It includes an ARM Cortex-M3 processor.

The chip supports multiple simultaneous Advanced Audio Distribution Profile (AADP) streams, enabling music sharing between multiple stereo Bluetooth headsets. The BCM2075 also contains on-chip processing for multimedia codecs including MP3, ADC, and AAC/AAC+ that reportedly allows the host to offload 90 percent of this processing to the BCM2075, further increasing battery life.

The GPS core of the BCM2075 uses a host-based integration architecture that splits the processing duties between the BCM2075 and the host CPU system. Broadcom acquired its GPS technology when the company bought Global Locate in 2007.
