BCM43455 Preliminary Data Sheet
Revision History
FEATURES
IEEE 802.11x Key Features
⢠IEEE 802.11ac compliant.
⢠Support for TurboQAM® (MCS0âMCS8
86 Mbps and MCS0âMCS9 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 à 5.27 mm,
0.4 mm pitch).
