BoosterPack Pinout 4 BOOSTXL-AUDIO Audio BoosterPack™ Plug-in Module SLAU670A – March 2016 – Revised November 2016 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Hardware www.ti.com The audio signal processing BoosterPack kit adheres to the 40-pin LaunchPad and BoosterPack pinout standard. This standard was created to aid compatibility between LaunchPad development kit and BoosterPack module tools across the TI ecosystem. The 40-pin standard is compatible with the 20-pin standard that is used by other LaunchPad kits like the MSP-EXP430G2 LaunchPad development kit. This allows for 40-pin BoosterPack modules to be used with 20-pin LaunchPad kits with some limited functionality. The BOOSTXL-AUDIO supports BoosterPack module stacking with its male and female BoosterPack headers. See how many BoosterPack modules you can stack onto your LaunchPad development kit to add more functionality like wireless and battery power. More information about compatibility can also be found at http://www.ti.com/launchpad. 2.1.2 Audio Output There are three options to select how the audio output is generated: the onboard TI DAC8311 digital-toanalog converter (DAC), a built-in DAC on the LaunchPad development kit, or a PWM that generates audio out. Select an option by moving the J5 jumper. 2.1.2.1 TI DAC8311 14-Bit Digital-to-Analog Converter The DAC8311 is a 14-bit low-power single-channel linear-voltage-output DAC. This DAC uses a 3-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces (see Table 1). The reference designator for the DAC8311 is U2. Move jumper J5 to the SPI DAC location to use the DAC8311 to generate the audio signal. More information on the DAC8311 DAC can be found at http://www.ti.com/product/dac8311. Table 1. DAC8311 Pinout 2.1.2.2 BoosterPack Header Connection Pin Function J1.8 DAC8311 Sync J1.9 SPI SCLK J5.10 SPI MOSI DAC Integrated on LaunchPad Development Kit If the LaunchPad development kit that the user has selected has an integrated DAC that is pinned out to the BoosterPack headers (for example, the MSP-EXP430FR5994), this DAC can be used to generate audio for the BOOSTXL-AUDIO BoosterPack plug-in module. The DAC output pin is J3.30 for the output of the onboard DAC on the LaunchPad development kit. Move jumper J5 to the LP DAC location to use the onboard DAC of the LaunchPad development kit to generate the audio signal. 2.1.2.3 PWM Audio A varying duty-cycle PWM can also generate audio. See Voice Band Audio Playback using a PWM DAC TI-Design for more information. Move jumper J5 to the PWM location to configure the audio input when using a PWM to generate the audio signal. Two pins can be used to drive the PWM audio: J2.19 (default) and J4.39 (alternate). To configure the BoosterPack module to use the alternate PWM pin, move the 0-Ω resistor on R9 to R10. 2.1.3 TI TS3A225E Audio Jack Detection The TS3A225E is an audio-headset switch device. This device detects the presence of a headset and an analog microphone and switches a system analog microphone pin between different connectors in an audio stereo jack. The microphone connection in a stereo connector can be swapped with the ground connection depending on manufacturer. When the TS3A225E detects a certain configuration, the device automatically connects the microphone line to the appropriate pin. The device also reports the presence of an analog microphone on an audio stereo jack. The reference designator for the TS3A225E is U1.

The human ear can hear frequencies of 0 to 20 kHz, and the operating range of the microphone is 20 Hz to 20 kHz. The reference designator for the microphone is MIC1, and the reference designator for the TLV2760 is U5. The microphone can also be powered on and off from GPIO pin J1.5 (default) or J4.31 (alternate) (see Table 2). To configure the microphone for its alternate pins, move the 0-Ω resistors on R1 and R4 to R3 and R5, respectively. For more information on the microphone, see http://www.puiaudio.com/pdf/pom-2242p-c33-r.pdf. Table 2. Microphone Pinout BoosterPack Header Connection Pin Function J1.6 Microphone Output (1) 2.1.5 J1.5 Microphone Power J3.26 (1) Alt Microphone Output J4.31 (1) Alt Microphone Power The alternate microphone output and power are required if also using the Sharp LCD BoosterPack plug-in module. Onboard Loudspeaker The onboard loudspeaker is a PUI ASE03008MR-LW150-R with reference designator S1. It is driven by an onboard audio amplifier, the TI TPA301, which has reference designator U4. The TPA301 is a bridgetied load (BTL) audio power amplifier developed for low-voltage applications where internal speakers are required. Operating with a 3.3-V supply, the TPA301 can deliver 250 mW of continuous power into a BTL 8-ohm load at less than 1% total harmonic distortion plus noise throughout voice-band frequencies. The TPA301 also uses a GPIO for turning on and off the amplifier using software through pin J2.13 (default) or J4.38 (alternate). To configure the amplifier on and off switch to use J4.38, move the 0-Ω resistor on R6 to R8. For more information on the loudspeaker, see http://www.puiaudio.com/pdf/ASE03008MR-LW150-R.pdf. 2.2 Power The board is designed to be powered by the attached LaunchPad development kit and requires 3.3 V. 2.3 2.3.1 Design Files Hardware See Section 5 for the schematics.
