Revision History
FEATURES
IEEE 802.11x Key Features
Bluetooth Key Features
•
•
IEEE 802.11ac compliant.
•
Complies with Bluetooth Core Specification
Version 4.1 with provisions for supporting future
specifications.
Support for TurboQAM® (MCS0–MCS8
86 Mbps and MCS0–MCS9 96 Mbps) HT20,
20 MHz channel bandwidth.
•
•
Bluetooth Class 1 or Class 2 transmitter
operation.
•
•
•
•
•
•
•
•
•
Single-stream spatial multiplexing up to
433.3 Mbps data rate.
Supports extended synchronous connections
(eSCO), for enhanced voice quality by allowing for
retransmission of dropped packets.
Supports 20, 40, and 80 MHz channels with
optional SGI (256 QAM modulation).
•
•
Adaptive frequency hopping (AFH) for reducing
radio frequency interference.
Full IEEE 802.11a/b/g/n legacy compatibility with
enhanced performance.
Interface support, host controller interface (HCI)
using a high-speed UART interface and PCM for
audio data.
Supports explicit IEEE 802.11ac transmit
beamforming.
TX and RX low-density parity check (LDPC)
support for improved range and power efficiency.
•
•
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.
On-chip power amplifiers and low-noise amplifiers
for both bands.
Support for optional front-end modules (FEM) with
external PAs and LNAs.
•
•
•
Low power consumption improves battery life of
handheld devices.
Supports optional integrated T/R switch for
2.4 GHz band.
Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
Supports RF front-end architecture with a single
dual-band antenna shared between Bluetooth
and WLAN for lowest system cost.
Automatic frequency detection for standard
crystal and TCXO values.
•
Shared Bluetooth and WLAN receive signal path
eliminates the need for an external power splitter
while maintaining excellent sensitivity for both
Bluetooth and WLAN.
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
•
•
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.
140-ball WLBGA package (4.47 mm × 5.27 mm,
0.4 mm pitch).
•
•
Supports standard SDIO v3.0 (including DDR50
mode at 50 MHz and SDR104 mode at 208 MHz,
4-bit and 1-bit) interfaces.
