Do you have auto-MCU with PMC input. We need UART 2ch and M0  class performance for other spec.

Thank you.

Sorry, I have my typo.

PCM is right.

Do you have auto-MCU with PCM input?

Hello Praveen-san, Bharadhwaj-san,

Thank you for your reply.

Yes, I mean Pulse Code Modulation.

We looking for auto MCU with direct PCM input pin  from external decoder as below system.

HDMI -> Decoder  -(PCM signal)->  "Auto-MCU" - (UART)-> bluetooh module -(BT)->  head phone with BT.

(auto-mcu and bluetooth module is on each sepatate board.)

I think Traveo 3200 faimily don't have direct PCM input pin and there is not above solution for auto MCU.

Is it ritght?

Best Regards,

Masya

Hi Masaya-san,

You could have a look at CYW20719 Bluetooth MCU. CYW20719 includes a PCM interface and is Bluetooth 5.0 compliant. It is automotive qualified.

However, there is one drawback, the PCM interface is used directly by the BT profiles and cannot be used natively. What profile are you planning to use? If you are planning to use HFP, then you could use CYW20719.

Hello yssu-san,

Thank you for your answer.

But , Customer need to separate between between BT module  and auto-MCU on each boards.

Thank you,

Masaya
