1 Functional Description

The SWA51 module is available in 2 variations; digital input transmitter module or digital output receiver
module.

There are three available I2S digital audio data inputs/outputs, each of these can be configured to operate as
either a master or a slave - depending on the application, the I2S ports can oper ate simultaneously as either
inputs or outputs. When configured as slaves, the I2S inputs/outputs can be inde pendently clocked by up to
two external masters. In addition, MCLK can be output from the module to provide a reference clock source to
an external ADC or DAC. MCLK can also be input to the module to provide a reference clock from an
external source.

The hardware for the audio input (transmit) a nd audio output (re ceive) versions of the module is id entical and
only the firmware loaded onto the module determines its function.

The highly integrated nature of the AV5100 transceiver IC results in few external components being required
for the SWA51 module design. 2 pr inted PCB antennas are u sed to achieve increased range, a nd to achieve
antenna spatial diversity. The extended-range RF path consists of the antennas, associated tuning
components, shield can, the RF switch, and two baluns, one connected to each of the RF input/output ports
on the AV5100 IC.

A 16MHz crystal oscillator generates the AV5100 fundamental system clock used as the basis for all RF and
digital audio clocks.

A 2Mb flash memory chip is used to store the module’s application firmware. The AV5100 is able to boot from
internal ROM upon first power up, which enables programming the flash chip with the application fir m ware . In
addition, Over-the-air Firmware upgrade capability can be enabled through the application firmware. The
module can be controlled from an external host device via the I2C Slave or the SPI Slave data interfaces. The
I2C master port allows the module to control other system audio devices such as a sub-woofer amplifier
system without having to add another MCU to the product design. Up to 9 additional GPIOs are available on
the SWA51 module (not including I2C and I2S signals) fo r implementing different UI features on the target
application. The resources mentioned above can be lever aged to implement low cost sub-woofer d esigns as
outlined below.

Signal Type Description

+3.3V Supply
Reset

I2S In Port

I2S Out Port

I2C Slave Port

I2C Master Port

The SWA51 hardware is configured to accept a nominal +3.3V supply.
Active low reset input. This pin is driven from an open collector/drain device such

that it can be pulled to ground for the active r eset state b ut, when r eleased , mu st
go to a high impedance state. This pin should not be actively driven high, as the
AV5100 internal reset circuit will not operate correctly.

The I2S input port can be co nfigured as a master or slave. Conse quently BCLK
and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by
the module on pin 16. Since the AV5100 IC contains a sample rate converter,
MCLK is not required to be supplied to the module when it is an I2S slave.
CMOS 3.3V logic levels are used for all I2S signals.

The I2S output port can be configured as a master or slave. Conseq uently BCLK
and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by
the module on pin 16. Since the AV5100 IC contains a sample rate converter,
MCLK is not required to be supplied to the module when it is an I2S slave.
CMOS 3.3V logic levels are used for all I2S signals.

The I2C slave port can be used for external host com munication and for module
testing. It is assumed that external pull up resistors are connected at the I2C
master communicating with the module.

The I2C master port is used to communicate with external audio devices such as
a sub-woofer amplifier. It is assumed that external pull up resistors are included
on the application board.

GPIOs

3.3V CMOS logic level GPIOs available to connect to other devices, or to use as
UI supporting GPIOs for LED and button support. All supported GPIOs can be
configured as outputs or inputs with configurable pull-ups/pull-downs.

different stuffing option.
(2) Utilizing pins 18 and 19 as USB D+ and D- requires the firmware to Tri-stat e GPIOs 22 and 23.
(3) Pin 20 (GPIO24) can be utilized to implement a “Data Waiting” interrupt signal for I2C and SPI Slave

data communication.
(4) Pin 21 (RESET_EXT) can be pulled to GND with a switch or an open drain/collector type device to

provide a hard reset signal to the AV5100. This pin is pulled up to VDDIO (3.3V) internally in the

AV5100 and should not be actively driven high.

I2C Master/Slave Communication Interface Timing (S_SCL, S_SDA)

3.10

The SWA51 has both I2C slave and master interfaces available with their respective pins S_SCL, S_SDA and
M_SCL, M_SDA. The interfaces operate in I2C fast-mode and can receive and transmit at up to 400 kbit/s.

Bytes are 8 bits long and are transferred with the most significant bit (MSB) first. Each byte has to be followed
by an acknowledge bit. The SWA51 will apply clock-stopping (by holding the clock lin e S_SCL LOW to force
the master into a wait state) if necessary due to internal high-priority tasks.

The slave/master interface can be used both for writing (e.g. sending commands) or reading (e.g. requesting
status). An additional GPIO pin on the SWA51 (Ex. GPIO24), can be used to notify the I2C master when a
pending message is ready to be sent.

The SWA51 slave interface responds to the 7-bit slave address 1000000 (0x40) as shown in Figure 1 below.
