AW-NB197SM BCM43438

AW-NB197SM
IEEE 802.11 b/g/n Wireless LAN ,
Bluetooth and FM Combo Stamp Module

1.General Description
Product Overview and Functional Description
AzureWave Technologies, Inc. introduces the advanced IEEE 802.11 b/g/n WLAN, Bluetooth and FM
combo module - AW-NB197SM. The module is targeted to mobile and embedded devices which need small
footprint package, low power consumption, and multiple OS support. The module supports 2.4GHz IEEE
802.11n MAC/baseband/radio, and Bluetooth 4.1 functionality. It also features an integrated Power
Management Unit (PMU), Power Amplifiers (PAs), and a Low Noise Amplifier (LNA) to address the needs of
mobile devices that require minimal power consumption and compact size. By using AW-NB197SM, the
customers can easily enable the Wi-Fi and BT embedded applications with the benefits of high design
flexibility, short development cycle, and quick time-to-market. Specified in the IEEE 802.11 standard
minimize the system power requirements by using AW-NB197SM. In addition to the support of WPA/WPA2
(personal) and WEP encryption, the AW-NB197SM also supports the IEEE 802.11i security standard through
AES and TKIP acceleration hardware for faster data encryption. For the video, voice and multimedia
applications the AW-NB197SM support 802.11e Quality of Service (QoS). The host interface is SDIO v2.0
interface.
For Bluetooth operation, the AW-NB197SM is Bluetooth 4.1 compliant. The Bluetooth transmitter also
features a Class 1 power amplifier. The AW-NB197SM 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 also incorporates all Bluetooth 4.1
features including Secure Simple Pairing, Sniff Subrating, and Encryption Pause and Resume. An
independent, high-speed UART is provided for the Bluetooth host interface. The Bluetooth subsystem
presents a standard Host Controller Interface (HCI) via a high speed UART and PCM for audio.
For FM receiver, the AW-NB197SM 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
FM subsystem supports the HCI control interface as well as I2S interfaces of the Bluetooth subsystem.
