Post by thread:[EE] TMS320DA150 Datasheet?

I'm looking for the datasheet for this processor...TI has no record of the part number and I'm having a heck of a time finding info about it. Apparently, it is "TMS320C54x based", whatever that means. The particular chip in question is, according to published accounts, in a BGA package with number of pins ~ 75 (I had to count on the schematic, and may have miscounted). For those curious, this is the brain in my new MP3 player (see http://www.neurosaudio.com). The entire product is open source, although they recently had some flap over something in their firmware that required that they temporarily "re-close" it. I'm trying to figure out the function of some of the pins on the processor so I can make some sense of the FM transmitting component and hopefully improve it somewhat (within legal limits, of course! ;-).
