Preliminary Data Sheet
BCM43303
Single-Chip IEEE 802.11 a/b/g/n
MAC/Baseband/Radio with Integrated
Bluetooth 4.0 and FM Transceiver
GE NE R AL DE S C RI PT ION
The Broadcom
®
BCM43303 single-chip device
provides for the highest level of integration for a
mobile wireless system, with integrated
IEEE 802.11 a/b/g and single-stream 802.11n (MAC/
baseband/radio), Bluetooth 4.0, and an FM radio
receiver and transmitter. It includes on-chip 2.4 GHz
and 5 GHz WLAN CMOS power amplifiers that meet
the output power requirements of most handheld
systems while permitting an optional external power
amplifier for higher output power applications, if
required.
Utilizing advanced design techniques and process
technology to reduce active and idle power, the
BCM43303 is designed to address the needs of highly
mobile devices that require minimal power
consumption and compact size. It includes a power
management unit that simplifies the system power
topology and allows for operation directly from a
mobile platform battery while maximizing battery life.
F E A T U RE S
The BCM43303 implements the highly sophisticated
Enhanced Collaborative Coexistence radio
coexistence algorithms and hardware mechanisms,
allowing for an extremely collaborative Bluetooth
coexistence scheme along with coexistence support
for external radios (such as GPS, WiMax, or Ultra
Wide-band radio technologies, as well as cellular
radios) and a single shared antenna (2.4 GHz
antenna for Bluetooth and WLAN). As a result,
enhanced overall quality for simultaneous voice,
video, and data transmission on a handheld system is
achieved.
For the WLAN section, two alternative host interface
options are included: an SDIO v2.0 interface that can
operate in 4b, 1b, or gSPI modes, and an HSIC
interface. An independent, high-speed UART is
provided for the Bluetooth host interface. The device
is packaged in a 4.89 mm × 5.33 mm WLBGA.

IEEE 802.11x Key Features
• Single-band 2.4 GHz 802.11 b/g/n or dual-
band 2.4 GHz and 5 GHz 802.11 a/b/g/n (non-
simultaneous)
• Single stream 802.11n support for 20 MHz
channels provides PHY layer rates up to
MCS7 (65 Mbps) for typical upper-layer
throughput in excess of 45 Mbps.
• Integrated CMOS power amplifiers with
internal power-detectors and closed-loop
power control can deliver greater than 18 dBm
of linear output power (in 2.4 GHz band).
• PAs can be powered directly from VBAT,
eliminating the need for a PALDO.
• Up to 8 RF control signals are available to
support optional external PAs for higher output
power and LNAs for enhanced sensitivity.
• Supports a single 2.4 GHz antenna shared
between WLAN and Bluetooth.
• Shared Bluetooth and WLAN receive signal
path eliminates the need for an external power
splitter while maintaining excellent sensitivity
for both Bluetooth and WLAN.
• Internal fractional nPLL allows support for a
wide range of reference clock frequencies
• Supports IEEE 802.15.2 external three-wire
coexistence scheme to optimize bandwidth
utilization with other co-located wireless
technologies such as GPS, WiMax, or UWB
• Supports standard SDIO v2.0 (50 MHz, 4-bit
and 1-bit), and gSPI (48 MHz) host interfaces.
• Alternative host interface supports HSIC (a
USB 2.0 derivative for short-distance, on-
board connections).
• Integrated ARM Cortex-M3 processor and on-
chip memory for complete WLAN subsystem
functionality, minimizing the need to wake up
the applications processor for standard WLAN
functions. This allows for further minimization
of power consumption, while maintaining the
ability to field upgrade with future features.
• OneDriver software architecture for easy
migration from existing embedded WLAN and
Bluetooth devices as well as future devices.
F E A T U RE S

• Adaptive Frequency Hopping (AFH) for reducing radio
frequency interference
• Interface support—Host Controller Interface (HCI) using
a high-speed UART interface and PCM for audio data
• The FM unit supports HCI for communication, stereo
analog input and output
• Low-power consumption improves battery life of

European Radio Data Systems (RDS) and the North
American Radio Broadcast Data System (RBDS)
standards
• Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound
• Automatic frequency detection for standard crystal and
TCXO values
• FM transmitter: 65 MHz to 108 MHz bands; supports both
RDS and the RBDS standards and programmable output
power.
