Preliminary Data Sheet
BCM4334X
Single Chip IEEE 802.11 a/b/g/n MAC/Baseband/Radio with
Integrated Bluetooth 4.0 + HS and FM Receiver
GENERAL DESCRIPTION
The Broadcom® BCM4334X single-chip device
provides the highest level of integration for a mobile
or handheld wireless system, with integrated
IEEE 802.11 a/b/g and single-stream IEEE 802.11n
MAC/baseband/radio, Bluetooth 4.0 + HS, and FM
radio receiver. It is designed to be used with external
2.4 GHz and 5 GHz front-end modules, which include
power amplifiers, low-noise amplifiers, and T/R
switches.
Using advanced design techniques and process
technology to reduce active and idle power, the
BCM4334X 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.
F EA T U RE S
The BCM4334X implements the highly sophisticated
Enhanced Collaborative Coexistence algorithms and
hardware mechanisms, allowing for an extremely
collaborative Bluetooth coexistence scheme along
with coexistence support for external radios (such as
cellular and LTE, GPS, WiMAX, and Ultra-Wideband)
and a single shared 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
(including gSPI) and a High-Speed Inter-Chip (HSIC)
interface (a USB 2.0 derivative for short-distance on-
board connections). An independent, high-speed
UART is provided for the Bluetooth host interface.

dual-band 2.4 GHz and 5 GHz IEEE 802.11 a/
b/g/n
• Single-stream IEEE 802.11n support for
20 MHz and 40 MHz channels provides PHY
layer rates up to 150 Mbps for typical upper-
layer throughput in excess of 90 Mbps.

block coding) and LDPC (low-density parity
check) options for improved range and
power efficiency.
• Up to 11 RF control signals are available to
support external PAs and LNAs.
• Supports a single 2.4 GHz antenna shared
between WLAN and Bluetooth.
• Shared Bluetooth and WLAN receive signal
