1-1. Product Overview and Functional Description

AzureWave Technologies, Inc. introduces the first IEEE 802.11b/g/n WLAN, Bluetooth and FM combo

module - AW-NH931. The module is targeted to mobile devices including, Digital Still Cameras (DSCs),

Portable Media Players (PMPs), and Gaming Devices, mobile phones which need small footprint

package, low power consumption, multiple OS support. By using AW-NH931, the customers can easily

enable the Wi-Fi, BT and FM embedded applications with the benefits of high design flexibility, short

development cycle, and quick time-to-market.

Compliance with the IEEE 802.11b/g/n standard, the AW-NH931 uses DSSS, OFDM, DBPSK, DQPSK,

CCK and QAM baseband modulation technologies. A high level of integration and full implementation of

the power management functions specified in the IEEE 802.11 standard minimize the system power

requirements by using AW-NH931. In addition to the support of WPA/WPA2 (personal) and WEP

encryption, the AW-NH931 also supports the IEEE 802.11i security standard through AES and TKIP

acceleration hardware for faster data encryption. The AW-NH931 is also Cisco Compatible Extension

(CCX) certified. For the video, voice and multimedia applications the AW-NH931 support 802.11e

Quality of Service (QoS).

For Bluetooth operation, the AW-NH931 is Bluetooth 2.1+Enhanced Data Rate (EDR) compliant. The

AW-NH931 supports extended Synchronous Connections (eSCO), for enhanced voice quality by

allowing for retransmission of dropped packets, and Adaptive Frequency Hopping (AFH) for reducing

radio frequency interference. It provides easier to connect devices, lower power consumption and

improved security.

For FM receiver/transmitter, the AW-NH931 is 76-MHz to 108-MHz FM bands supported and supports

the European Radio Data Systems (RDS) and the North American Radio Broadcast Data System

(RBDS) modulations.

The AW-NH931 supports standard interface SDIO v1.2

interface for BT/FM host controller interface, and PCM for BT audio data. The demodulated FM audio

signal is available as line-level analog stereo output. AW-NH931 is suitable for multiple mobile

processors for different applications. With the combo functions and the good performance, the AW-

NH931 is the best solution for the consumer electronics and the laptops.

2-4. BT/FM Host Interface

The AW-NH931 is the optimal solution for any voice or data application that requires the Bluetooth SIG

standard Host Controller Interface (HCI) using a high-speed UART. The FM subsystem and the

Bluetooth subsystem share the same high-speed UART

2-4-1. UART Interface

The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, CTS) with adjustable baud

rates from 9600 bps to 4.0 Mbps. The interface defaults to a baud rate of 115.2 Kbps coming out of reset.

The desired high-speed baud rate may be selected via a vendor-specific UART HCI command. The AW-

NH931 has a 480-byte receive FIFO and a 480-byte transmits FIFO to support EDR. The interface

supports the Bluetooth 2.1 UART HCI (H4) specification. The default baud rate for H4 is 115.2 k baud.

In order to support both high and low baud rates efficiently, the UART clock can be selected as either 24

or 48 MHz. Generally, the higher speed clock is needed for baud rates over 3 M baud, however a lower

speed clock may be used to achieve a more accurate baud rate under 3 M baud.

The legacy method of programming the high-speed baud rate of the AW-NH931 UART using DHBR and

DLBR values is also supported for backward compatibility with previous-generation Bluetooth devices.

Normally, the UART baud rate is set by a configuration record downloaded after reset, or by automatic

baud rate detection and the host does not need to adjust the baud rate. Support for changing the baud

rate during normal HCI UART operation is included through a vendor-specific command that allows the

host to adjust the contents of the baud rate registers.

The AW-NH931 UART operates correctly with the host UART, provided the combined baud rate error of

the two devices is within ±5%
