General Description

F2M03MLA is a low power embedded Bluetooth™ v2.0 multimedia module with an on board antenna, integrated stereo amplifier and a 32 bit digital signal processor (DSP) allowing enhanced audio algorithms such as MP3 decoding and advanced echo cancellation as well as other general purpose applications. The module is a fully Bluetooth™ compliant device for audio and data communication. With a transmit power of up to +7dBm and receiver sensibility of down to –81dBm combined with stereo sound and low power consumption the F2M03MLA is suitable for the most demanding audio applications. The module is fully Bluetooth™ v2.0 qualified and it is certified according to CE and FCC, which give fast and easy Plug-and-Go implementation and short time to market.

F2M03MLA has by default the Wireless Audio firmware consisting of four Bluetooth profiles: Stereo Headset, HandsFree, A2DP and the AVRCP profile. The module can optionally be delivered with customized firmwares.

Low power Multimedia Bluetooth™ Module with antenna F2M03MLA

Datasheet

5 Firmware versions

F2M03MLA is supplied with Bluetooth stack firmware, which runs on the internal RISC micro controller of the Bluetooth module. This chapter includes an overview of the different options for more in depth information please use separate firmware datasheets provided by Free2move.

All firmware versions are compliant with the Bluetooth specification v2.0. The F2M03MLA software architecture allows Bluetooth processing to be shared between the internal micro controller and a host processor. Depending on application the upper layers of the Bluetooth stack (above HCI) can execute onchip or on the host processor.

Running the upper stack on the F2M03MLA module reduces (or eliminates, in the case of a on module application) the need for host-side software and processing time.

The integration approach depends on the type of product being developed. For example, performance will depend on the integration approach adopted. In general Free2move offers two categories of Bluetooth stack firmware for the F2M03MLA:

• Wireless Audio (WA) is Free2move’s standard firmware for audio applications. It is intended for Headset and audio streaming applications. It currently supports the Headset, HandsFree, A2DP and AVRCP profile. There is no need for additional drivers or Bluetooth software on a host.

• Customised firmwares. Free2move have the possibility to customise firmwares for a special customer applications.

5.1 Wireless Audio

Wireless Audio is Free2move’s standard firmware for audio applications. It is intended for Headset and audio streaming applications.

The current version of the Wireless Audio includes the Headset, HandsFree, A2DP and AVRCP Bluetooth profiles. Additional profiles or functionalities may be included in future versions of Wireless Audio.

Please contact Free2move for a complete datasheet of the Wireless Audio firmware.

5.1.1 Supported Bluetooth profiles

Stereo Headset (HSP) and Handsfree Profile (HFP)

The Stereo Headset and HandsFree profile is used for full duplex audio connections to phones and similar for telephone call purpose.

Wireless Audio supports both the Headset and the HandsFree profile. The profile of choice depends on what the connecting device support. If the Wireless Audio firmware initiates the connection it will first try to use the Handsfree profile. If the connecting device not support the HandsFree profile, it will choose the Headset profile.

Advanced Audio Distribution Profile (A2DP)

The A2DP profile is used for high quality stereo audio streaming.

Wireless Audio supports the A2DP sink which makes it possible to receive audio streams from a A2DP source.

Audio/Video Remote Control Profile(AVRCP)

The AVRCP profile is used for controlling the Audio stream.

5.2 Customised firmwares

Customised firmwares can be made upon request. Free2move have the possibility to produce modules with customer specific settings of the Wireless Audio firmware (most applicable in large production volumes). Free2move can also provide special firmwares for customer applications.

Please consult your reseller for more information about customised firmwares and special requirements.

6 Device terminal description

6.1 Stereo Audio Interface

The main features of the interface are:

• Stereo and mono analogue input for voice band and audio band

• Stereo and mono analogue output for voice band and audio band

• Support for stereo digital audio bus standards such as I

• Support for IEC-60958 standard stereo digital audio bus standards i.e. S/PDIF and AES3/EBU

• Support for PCM interfaces including PCM master CODECs that require an external system clock

Rev: b

Stereo CODEC Audio input and output stages

The stereo audio CODEC uses a fully differential architecture in the analogue signal path, which results in low noise sensitivity and good power supply rejection while effectively doubling the signal amplitude.

Important Note:

To avoid any confusion with respect to stereo operation this datasheet with respect to hardware explicitly states which is the left and right channel for audio input and output.

For mono operation F2M03MLA uses the left channel for standard mono operation for audio input and output.

Low power Multimedia Bluetooth™ Module with antenna F2M03MLA

Datasheet

6.1.1 ADC

The ADC consists of two second order Sigma Delta converters allowing two separate channels that are identical in functionality.

ADC Sample Rates

Each ADC supports the following sample rates:

• 8kHz

• 11.025kHz

• 16kHz

• 22.05kHz

• 24kHz

• 32kHz

• 44.1kHz

ADC Gain

The ADC contains two gain stages for each channel, an analogue and a digital gain stage. The digital gain stage has a range of –24dB to +21.5dB.

The ADC analogue amplifier is a two stage amplifier. The first stage of the analogue amplifier is responsible for selecting the correct gain for either microphone input or line input and therefore has two gain settings, one for the microphone and one for the line input. In simple terms the first stage amplifier has a selectable 20dB gain stage for the microphone and this creates the dual programmable gain required for the microphone or the line input. The equivalent block diagram for the two stage is shown in the figure below.

First and second stage of ADC analogue amplifier block diagram

The second stage of the analogue amplifier has a programmable gain with seven individual 3dB steps. In simple terms, by combining the 20dB gain selection of the microphone input with the seven individual 3dB gain steps, the overall range of the analogue amplifier is approximately -4dB to 40dB. The overall gain setting of the ADC is a combined function of the digital and analogue amplifier settings, so that the fullscale range of the input to the ADC is kept to approximately 400mV rms.

6.1.2 DAC

The DAC consists of two second order Sigma Delta converters allowing two separate channels that are identical in functionality.

DAC Sample rates

Each DAC supports the following samples rates:

• 48kHz

• 44.1kHz

• 32kHz

• 24kHz

• 22.050kHz

• 16kHz

• 11.025kHz

• 8kHz

DAC Gain

The DAC contains two gain stages for each channel, a digital and an analogue gain stage. The digital gain stage has a programmable selection value in the range of –24dB to 21.5dB.

The DAC analogue amplifier unlike the ADC is a single stage amplifier with the same structure as the second stage of the ADC analogue amplifier. The structure of the DAC analogue amplifier is similar to the second stage of the ADC analogue amplifier.

The overall gain setting of the DAC is a combined function of the digital and analogue amplifier settings, therefore for a 1V rms nominal digital output signal from the digital gain stage of the DAC, the approximate output values of the analogue amplifier of the DAC is in the range of 0dB to –21dB.

6.1.3 Mono Operation

Mono operation is single channel operation of the stereo CODEC. The left channel represents the single mono channel for audio in and audio out. In mono operation the right channel is auxiliary mono channel that may be used in dual mono channel operation.
