BCM43455 Preliminary Data Sheet
Revision History
FEATURES
IEEE 802.11x Key Features
• IEEE 802.11ac compliant.
• Support for TurboQAM® (MCS0–MCS8
86 Mbps and MCS0–MCS9 96 Mbps) HT20,
20 MHz channel bandwidth.
• Single-stream spatial multiplexing up to
433.3 Mbps data rate.
• 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.
• Supports explicit IEEE 802.11ac transmit
beamforming.
• TX and RX low-density parity check (LDPC)
support for improved range and power efficiency.
• On-chip power amplifiers and low-noise amplifiers
for both bands.
• Support for optional front-end modules (FEM) with
external PAs and LNAs.
• Supports optional integrated T/R switch for
2.4 GHz band.
• Supports RF front-end architecture with a single
dual-band antenna shared between Bluetooth
and WLAN for lowest system cost.
• Shared Bluetooth and WLAN receive signal path
eliminates the need for an external power splitter
while maintaining excellent sensitivity for both
Bluetooth and WLAN.
• Internal fractional-n PLL allows support for a wide
range of reference clock frequencies.
• Supports IEEE 802.15.2 external coexistence
interface to optimize bandwidth utilization with
other co-located wireless technologies such as
LTE or GPS.
• Supports standard SDIO v3.0 (including DDR50
mode at 50 MHz and SDR104 mode at 208 MHz,
4-bit and 1-bit) interfaces.
Bluetooth Key Features
• Complies with Bluetooth Core Specification
Version 4.1 with provisions for supporting future
specifications.
• Bluetooth Class 1 or Class 2 transmitter
operation.
• Supports extended synchronous connections
(eSCO), for enhanced voice quality by allowing for
retransmission of dropped packets.
• Adaptive frequency hopping (AFH) for reducing
radio frequency interference.
• Interface support, host controller interface (HCI)
using a high-speed UART interface and PCM for
audio data.
• FM unit supports HCI for communication.
• 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.
• Low power consumption improves battery life of
handheld devices.
• Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
• Automatic frequency detection for standard
crystal and TCXO values.
General Features
• Supports battery voltage range from 3.0V to 5.25V
supplies with internal switching regulator.
• Programmable dynamic power management
• 6 Kbit OTP for storing board parameters.
• GPIOs: 15
• 140-ball WLBGA package (4.47 mm × 5.27 mm,
0.4 mm pitch).
