Hi all,

I need to transfer streaming audio data form I2S to USB. Which product of the MSP430 family can do this job?

Thanks

Depend on what you want on PC side, how to see your connected device (Bulk / CDC), and if (possible, but not guaranteed) 1 MB/s rate is enough. MSP430F5xx USB family (depending on coding/decoding audio data) can be used for this, but MSP430 don't have I2S hardware support, so some glue logic is needed...

I need to transfer 44.1KHz, 16bit audio (over I2S) to USB Audio. Does TI have any product for direct conversion of I2S to USB Audio?

TI have just USB codecs with ADC/DAC, some have S/PDIF in addition. If you look for I2S to USB and nothing else then perhaps you shall consider TMS320C55xx series DSP with USB and I2S on board.
