Broadcom Combines Wi-Fi, Bluetooth & FM Into One Chip
Broadcom today announced the industry’s most advanced single-chip connectivity solution that combines the company’s market-leading Wi-Fi®, Bluetooth® and FM receiver technologies onto a single silicon die. This combination of popular radio capabilities in a new ultra-low power 65 nanometer CMOS system-on-a-chip (SoC) allows OEMs to provide the richest connectivity features without a prohibitive impact on product cost, size or battery life. No other silicon provider can match Broadcom’s positions in both the Bluetooth and Wi-Fi markets, or offer the low-power benefits enabled by the advanced 65nm process in which this chip was developed. The Broadcom BCM4325 Wi-Fi/Bluetooth/FM receiver is now sampling to early access customers.
Broadcom Corporation (Nasdaq: BRCM), a global leader in semiconductors for
wired and wireless communications, today announced the industry’s most advanced
single-chip connectivity solution that combines the company’s market-leading
Wi-Fi®, Bluetooth® and FM receiver technologies onto a single silicon die. This
combination of popular radio capabilities in a new ultra-low power 65 nanometer
CMOS system-on-a-chip (SoC) allows OEMs to provide the richest connectivity
features without a prohibitive impact on product cost, size or battery life. No
other silicon provider can match Broadcom’s positions in both the Bluetooth and
Wi-Fi markets, or offer the low-power benefits enabled by the advanced 65nm
process in which this chip was developed.
Mobile handsets, media players and handheld wireless systems have made recent
leaps in sophistication, enabling service providers to offer compelling
applications such as web browsing, instant messaging, e-mail, advanced
multimedia, VoIP phone calls, photo sharing, as well as innovative connected
services like weather and personal navigation. Critical to the success of these
advanced handheld devices (which are now appearing in the market) are ultra-low
power solutions for Wi-Fi, Bluetooth and other radio technologies that enable an
array of connectivity options. Adding multiple additional chips to mobile
devices, however, impedes the trend toward increasing compact, low-power
products. Until now, integrating these technologies in a single product was
challenging since multiple radios in the same band can lead to
self-interference. Broadcom has solved these issues with today’s product
"Integrating multiple wireless technologies onto a single chip is a landmark
achievement that will be welcomed by mobile device manufacturers due to the
inherent cost, space and power savings it will enable," said Stuart Carlaw,
Wireless Research Director at ABI Research. "By leveraging its unique expertise
in Wi-Fi, Bluetooth and FM radio, Broadcom has broken through a major technical
barrier that will help accelerate the feature sets of the next-generation of
connected mobile devices."
"Mobile handsets are rapidly evolving into the central point of personal
communications, entertainment and information for large numbers of consumers,"
said Robert A. Rango, Senior Vice President and General Manager of Broadcom’s
Wireless Connectivity Group. "Our new Bluetooth, Wi-Fi and FM transceiver will
help to drive this evolution and enhance devices like digital music players by
dramatically reducing the cost and complexity of these key wireless technologies
in innovative mobile devices."
Having shipped hundreds of millions of Wi-Fi and Bluetooth products, Broadcom is
the only company that can combine these technologies into a single solution that
provides the highest level of integration with industry leading hardware and
software. Broadcom’s integrated solution offers advanced co-existence algorithms
to maximize the performance of multiple wireless connectivity options within a
single device. Even as FM radio continues to gain momentum in handsets,
Broadcom’s implementation offers the advanced features required for
entertainment and live news broadcast reception in today’s handset products.
Announced today is the Broadcom® BCM4325 Wi-Fi/Bluetooth/FM transceiver. This
single-chip solution provides the highest level of integration for mobile or
handheld wireless systems featuring IEEE 802.11a/b/g (MAC, baseband and radio),
support for Bluetooth 2.0 plus enhanced data rate (EDR) that is upgradeable to
version 2.1 and an advanced FM receiver. Unlike competing technologies, the
BCM4325 was designed in the advanced 65 nanometer process to address the
critical challenges within mobile devices. It provides the lowest power,
smallest form factor and most robust connectivity, allowing OEMs to drive these
wireless technologies into more handset platforms.
Adding both Wi-Fi and Bluetooth to small consumer devices, such as mobile
handsets, presents significant integration challenges for any silicon provider.
The highly integrated BCM4325 design addresses these silicon challenges by
reducing the overall footprint size and required external components. The
BCM4325 is an ultra-low power solution utilizing advanced design techniques that
deliver the lowest active and idle power consumption (up to 40% lower than
competitive solutions) combined with a software architecture that offloads the
host processor to dramatically extend handheld device battery life and reduce
The BCM4325 utilizes 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 2.4 GHz 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 also supports all of the rich features included with the Bluetooth
2.0 specifications and is upgradeable to Version 2.1 of the standard. The FM
radio receiver supports the European Radio Data Service (RDS) and the North
American Radio Broadcast Data Service (RBDS) with superior tuning capabilities.
These unique advances enable the BCM4325 to enhance the overall handset user
experience for simultaneous voice, video and data communications on a low power
mobile system. In addition, the flexible software architecture simplifies the
migration from a single radio connectivity technology (WLAN or Bluetooth) to a
multi-radio technology solution, minimizing the software design changes while
maximizing reuse of the vast array of mature software available for Broadcom’s
WLAN and Bluetooth based products.
The Broadcom BCM4325 Wi-Fi/Bluetooth/FM receiver is now sampling to early access
customers. Pricing is available upon request.
