BCM4354 Data Sheet
Revision History
FEATURES
IEEE 802.11X Key Features
•
•
PCIe mode complies with PCI Express base
specification revision 3.0 for ×1 lane and power
management running at Gen1 speeds.
•
•
IEEE 802.11ac Draft compliant.
Dual–stream spatial multiplexing up to
867 Mbps data rate.
Integrated ARMCR4™ processor with tightly coupled
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. On–chip memory includes 768 KB SRAM and
640 KB ROM.
•
•
•
Supports 20, 40, and 80 MHz channels with
optional SGI (256 QAM modulation).
Full IEEE 802.11a/b/g/n legacy compatibility
with enhanced performance.
TX and RX low–density parity check (LDPC)
support for improved range and power
efficiency.
•
OneDriver™ software architecture for easy migration
from existing embedded WLAN and Bluetooth devices
as well as future devices.
•
•
Supports IEEE 802.11ac/n beamforming.
On–chip power amplifiers and low–noise
amplifiers for both bands.
Bluetooth and FM Key Features
•
Supports various RF front–end architectures
including:
•
Complies with Bluetooth Core Specification Version 4.1
with provisions for supporting future specifications.
– Two antennas with one each dedicated to
Bluetooth and WLAN.
•
•
Bluetooth Class 1 or Class 2 transmitter operation.
Supports extended synchronous connections (eSCO),
for enhanced voice quality by allowing for retransmission
of dropped packets.
– Two antennas with WLAN diversity and a
shared Bluetooth antenna.
•
Shared Bluetooth and WLAN receive signal
path eliminates the need for an external
power splitter while maintaining excellent
sensitivity for both Bluetooth and WLAN.
•
•
Adaptive frequency hopping (AFH) for reducing radio
frequency interference.
Interface support, host controller interface (HCI) using a
USB or high–speed UART interface and PCM for audio
data.
•
•
Internal fractional nPLL allows support for a
wide range of reference clock frequencies
•
•
•
USB 2.0 full–speed (12 Mbps) supported for Bluetooth.
The FM unit supports HCI for communication.
Supports IEEE 802.15.2 external
coexistence interface to optimize bandwidth
utilization with other co–located wireless.
technologies such as LTE or GPS.
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 standard SDIO v3.0 (up to SDR104
mode at 208 MHz, 4–bit and 1-bit) host
interfaces.
•
•
Backward compatible with SDIO v2.0 host
interfaces.
•
•
•
Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
Alternative host interface supports HSIC v1.0
Automatic frequency detection for standard crystal and
TCXO values.
Supports serial flash interfaces.
