GENERAL DESCRIPTION
The Broadcom® BCM4330 single chip device provides for the highest level of integration for a mobile or handheld wireless system, with integrated IEEE 802.11™ a/b/g and single-stream 802.11n (MAC/baseband/radio), Bluetooth® 4.0 + HS, and 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 BCM4330 is designed to address the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life.
FEATURES
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
(72 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.
Bluetooth and FM Key Features
• Bluetooth Core Specification Version 4.0 + HS compliant
with provisions for supporting future specifications
• Bluetooth Class 1 or Class 2 transmitter operation
• Supports extended Synchronous Connections (eSCO), for
enhanced voice quality by allowing for retransmission of
dropped packets
• 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
handheld devices
• FM receiver: 65 MHz to 108 MHz FM bands; supports the
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.
General Features
