Using 65nm process technology, Broadcom Corp. is producing a low-power SoC that combines Wi-Fi, Bluetooth and FM receiver technologies onto a single silicon die, allowing OEMs to drive these wireless technologies into more handset platforms.

The BCM4325 Wi-Fi/Bluetooth/FM transceiver is a highly integrated SoC, featuring IEEE 802.11a/b/g (MAC, baseband and radio), support for Bluetooth 2.0 + enhanced data rate (EDR) that is upgradeable to version 2.1 and an advanced FM receiver.

According to Broadcom, the BCM4325 employs advanced design techniques that deliver the lowest active and idle power consumption (up to 40 percent lower than competitive products) combined with a software architecture that offloads the host processor to extend handheld device battery life and reduce memory requirements.

The BCM4325 employs BroadRange technology, which provides robust range performance to ensure consistent connections to the Wi-Fi access points. The chip also features Broadcom's InConcert technology, which consists of sophisticated software algorithms and hardware mechanisms that enable collaborative co-existence between Wi-Fi and Bluetooth, since both operate in the 2.4GHz radio frequency range.

By integrating Bluetooth with WLAN, the BCM4325 can more intelligently operate both technologies, allowing the option for a shared antenna system to further reduce board area requirements and provide the capability to co-exist with additional external radio technologies.

The BCM4325 Wi-Fi/Bluetooth/FM receiver is sampling today to early access customers. Contact Broadcom for pricing.
