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 and 5GHz bands single-stream IEEE 802.11n MAC/baseband/radio, and Bluetooth 4.0 + HS 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-AM634NF, 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.
For the WLAN operation, the AW-AM634NF uses DSSS, OFDM, DBPSK, DQPSK, CCK and QAM baseband modulation technologies. It supports 20 MHz and 40 MHz channels provide PHY layer rates up to 150 Mbps. 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-AM634NF. In addition to the support of WPA/WPA2 (personal) and WEP encryption, the AW-AM634NF 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-AM634NF support 802.11e Quality of Service (QoS). The host interface is SDIO v2.0 interface.
For Bluetooth operation, the AW-AM634NF is Bluetooth 4.0 + HS compliant. The Bluetooth transmitter also features a Class 1 power amplifier with Class 2 capability. The AW-AM634NF 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 4.0 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.
