TLV320AIC3254 programming

Other Parts Discussed in Thread: TLV320AIC3254

Hello experts,

I am new to TLV320AIC3254 chip and really interested in using it in my audio application. I am planning to use the evaluation module first. My question is, the data sheet says "programmable mini DSPs. Does that mean once we program the chip (using the software/ pure path), is it going to work stand alone without a microprocessor. If we do not want to change/ adjust the settings or parameters, while we use it in a product, can we save the desired setting to the chip and apply it to a product (like a microcontroller) and expect it to be work?. Any advice would be greatly appreciated.

Best regards,

Sam

    Hi, Sam,

    Unfortunately, the miniDSP code and I2C registers are all made with volatile memory, so you need to program the device every time you boot your system.

    We have a pretty slick little app note that describes how to do this with a simple MSP430. Click HERE to read it.

    Hi Don,

    Thank you very much for your guidance. If I prgramm to registers could you please let me know what is the correct starting sequence?. I mean, which registers I need to access just to get started (hear the sound) without changing available parameters?

    Thank you!

    Sam
