AVNERA PROPRIETARY & CONFIDENTIAL | PROVIDED UNDER NDA

General Description

Every consumer wants to be free from wires,

but it has been challenging to find a low-cost,

high-quality, easy-to-use wireless audio

solution for the wireless subwoofer market.

Avnera’s proprietary wireless system takes a

new approach to wireless audio. The wireless

protocol was designed from the ground up and

delivers uncompressed mono or stereo audio,

with fixed latency and variable over the air

data rate support to eliminate interference

problems at the best possible audio quality.

Avnera’s wireless modules offer a low-touch,

easy-to-integrate wireless audio solution and

enable fast time to market by already solving

the problem associated with FCC certification,

antenna tuning and board optimization.

Modules based on Avnera’s AV6200 silicon

provide breakthrough wireless audio

functionality with fixed low-latency point-to-

point transport of uncompressed mono PCM

audio data at up to 48KHz, 16-bit resolution

using digital (I2S) interfaces.

AudioMagic AVMD6210-SWA12 Module Brief PRELIMINARY v0p1 4 AVMD6210-SWA12- Connector Information Table 1 shows the module connector pin out for the SWA12. A goal of the design is to have the exact same pin out for both the Tx and Rx modules. The module function is completely determined by firmware. The module pins provide the capability to use either SPI slave or I2C slave interfaces – these are mutually exclusive. If an I2C slave host interface is used GPIOs 2 and 3 can be used for general purpose I/O.

AudioMagic AVMD6210-SWA12 Module Brief PRELIMINARY v0p1 6 Electrical Specifications 6.1 Absolute Maximum Ratings Absolute Maximum Ratings (AMR) are stress ratings only. AMR corresponds to the maximum value that can be applied without leading to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may cause permanent damage to the device.

AudioMagic AVMD6210-SWA12 Module Brief PRELIMINARY v0p1 7 Firmware Architecture 7.1 Standard Firmware Options Avnera provides standard firmware images that implement basic wireless link operation. Each of these images uses 1 GPIO as a link status indicator and another GPIO is an input used to get the module into pairing mode as illustrated in Figure 4.

AudioMagic AVMD6210-SWA12 Module Brief 7.3 Firm PRELIMINARY v0p1 ware Upgrades The possible interfaces that can be used for upgrades of the flash memory device are shown in Figure 5. With the standard firmware implementation, firmware upgrades are achieved by using the module SPI master port to directly program the module flash device. Avnera provides a GUI application that runs on a PC to facilitate direct SPI programming.
