MIC and Speaker On CC2560-EV + MSP430F5438-EV board

Other Parts Discussed in Thread: CC2560, TLV320AIC3100

Hey,

I am currently researching on building a bluetooth based intercom device using the HSP/HFP bluetooth profiles. I came across the CC2560, but I am a little unsure about using HSP/HFP with the device.

According to the data sheet in order to use HFP I need an external audio codec attached the I2S/PCM port of the cc2560 is this correct?

Can someone recommend external audio codec? I found the TLV320AIC3100 it seems like it would do the job it has it has both a DAC and mono audio ADC, it also has a mono 4ohm speaker driver.

Also just one more thing the cc2560 work only through HCI commands from the host MCU (MSP430) is this correct? In other word the cc2560 always require a host MCU to work?

Hi,

You can take a look at the CC2564B datasheet (www.ti.com/.../cc2564modn).

This has support for assisted mode HFP WBS where the encoding/decoding happens on the device itself rather than in the host, thus minimizing host processing and power.

More details in the DS.

Gigi Joseph.

Where can i find the evaluation module for this? I do not see it listed on TI website. Is there one?
