Hello,
We have recently been using the TAS1020B for audio processing circuit development (TAS5548EVM).
Although it has been discontinued and its page has been removed, I was able to access the historical page of the product through the Web Archive (https://web.archive.org/web/20111222065220/http://www.ti.com/product/tas1020b).
I would like to inquire if it's possible to provide the Firmware Development Kit (FDK) for TAS1020B.
Steven
