Microcontroller for audio codec

Other Parts Discussed in Thread: MSP430F5528, MSP430F5510

Hey

I am developing an Audio codec using the TIs AIC3254 chip.

For the interface, they have suggested a USB streaming controller which they no longer support and other alternatives are a full blown Audio DSP chips, which does not makes sense since I am developing with an Audio codec already. I just need an interface to have it programmed with USB.

So what kind of a microcontroller could be suitable, that is its specs, like memory, RAM, etc. I just require only a microcontroller with I2S support.

Since, the only program I want to run are bass extension and equalization, which the PurePath already provides, so for that what could be the minimum specs that would help to make it run efficiently. Wouldn't mind using an external Serial EEPROM, if microcontroller is costly for that memory.

This ROM is what is used in the reference schem - http://www.microchip.com/wwwproducts/Devices.aspx?product=24AA256

Thanks.

Thanks.

    Hi Arjun,

    You are right about the TAS1020B being NRND.

    I have used the MSP430F5510 (32kB) and MSP430F5528 (128kB) with AIC devices to do HID to I2C and also store miniDSP code in them. However, these chips do not support USB Audio and do not have I2S.

    You might want to check in the MSP430 forum if they have something with I2S.

    Regards,
