Mark asked:
Does anyone have a data sheet for the Sony V7021 IC?
This is a video decoder
That's not a Sony part number. Sony used
CX<digits><suffix>
on older stuff, and
CX<letter><digits><suffix>
on newer stuff, where letter is M for memory, P for processor, A for analog,
D for other digital, etc.
What other numbers are on the part? Does it actually bear a Sony logo?
