Preliminary Data Sheet
BCM4339
Single-Chip 5G WiFi IEEE 802.11ac MAC/Baseband/Radio
with Integrated Bluetooth 4.1 and FM Receiver
GENERAL DESCRIPTION
GENERAL DESCRIPTION
®
The Broadcom BCM4339 single-chip device provides
Using advanced design techniques and process
technology to reduce active and idle power, the
BCM4339 is designed to address the needs of 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 direct operation from a mobile platform
battery while maximizing battery life.
the highest level of integration for a mobile or
handheld wireless system with integrated single-
stream IEEE 802.11ac MAC/baseband/radio,
Bluetooth 4.1 and FM radio receiver. In IEEE 802.11ac
mode, the WLAN operation supports rates of MCS0–
MCS9 (up to 256 QAM) in 20 MHz, 40 MHz, and 80
MHz channels for data rates up to 433.3 Mbps. In
addition, all the rates specified in IEEE 802.11a/b/g/n
are supported. Included on-chip are 2.4 GHz and
5 GHz transmit amplifiers, and receive low-noise
amplifiers. Optional external PAs, LNAs, and antenna
diversity are also supported.
The BCM4339 implements highly sophisticated
enhanced collaborative coexistence hardware
mechanisms and algorithms, which ensure that
WLAN and Bluetooth collaboration is optimized for
maximum performance. In addition, coexistence
support for external radios (such as LTE cellular,
GPS, and WiMAX) is provided via an external
interface. As a result, enhanced overall quality for
simultaneous voice, video, and data transmission is
achieved.
For the WLAN section, several alternative host
interface options are included: an SDIO v3.0 interface
that can operate in 4b, 1b, or gSPI modes and a PCIe
Gen1 interface (3.0 compliant). For the Bluetooth
section, host interface options of a high-speed 4-wire
UART and USB 2.0 full-speed (12 Mbps) are
provided.
