Data Sheet
BCM43242
Single-Chip IEEE 802.11 a/b/g/n 2x2 MAC/
Baseband/Radio with Integrated Bluetooth 4.0 + HS
GENERAL DESCRIPTION
The Broadcom® BCM43242 is a single-chip device for
wireless media systems. It integrates the MAC,
baseband, and radio of IEEE 802.11 a/b/g and
2×2 IEEE 802.11n with Bluetooth 4.0 + HS.
The BCM43242 takes advantage of the high
throughput and extended range of the Broadcom
second-generation MIMO solution. With MIMO, the
information is sent and received over two or more
antennas, simultaneously using the same frequency
band, thus providing greater range and higher
throughput, while maintaining compatibility with
legacy IEEE 802.11a/b/g devices. This is
accomplished through a combination of enhanced
MAC and PHY implementations including spatial
multiplexing modes in the transmitter and receiver,
and advanced digital signal processing techniques to
improve receive sensitivity. The BCM43242
architecture, with its fully integrated dual-band radio
transceiver, supports 2 × 2 antennas. It also supports
20 and 40 MHz channels, allowing for PHY Layer
throughput up to 300 Mbps.
Using advanced design techniques and process
technology to reduce active and idle power, the

FEATURES
BCM43242 is designed to address the needs of
media-embedded applications 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 3.3V or 5V supply, which provides
flexibility. The BCM43242 includes power saving
schemes such as single-core listen (OCL), single-
core demodulation of SISO/STBC packets, and
dynamic maximum likelihood (ML) demapping (which
is based on channel conditions).
The BCM43242 implements the highly sophisticated
Enhanced Collaborative Coexistence radio
coexistence algorithms and hardware mechanisms.
As a result, enhanced overall quality for simultaneous
audio, video, and data transmission for home
entertainment devices is achieved.
The WLAN host interface is USB 2.0. The Bluetooth
host interface options include full-speed USB 1.1 and
a high-speed UART.
