Preliminary Data Sheet
BCM4330
Single Chip IEEE 802.11™ a/b/g/n MAC/Baseband/
Radio with Integrated Bluetooth® 4.0 + HS and FM
Transceiver
GENERAL DESCRIPTION
FEATURES
The Broadcom® BCM4330 single chip device provides
for the highest level of integration for a mobile or
handheld wireless system, with integrated
The BCM4330 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.
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.
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. Package
options include 4.89 mm x 5.33 mm WLBGA and
WLCSP, and 6.5 mm x 6.5 mm FCFBGA.
