Hi guys,
I've looked trough my Z80 Stuff some minutes before b'cause a friend wanted
an Z80A CPU, ok found it. In a Bag 6 uPD780-1 which are also Z80A's, I found
two uPD7201C. I've googeled some time before that the uPD7201A is some
Z80-SIO - alike, has an other Pinout for example and should be compatible
Well, it's synchronous/asynchronous serial chip, but I don't think it's
very similar to the Z80-SIO
to some Intel chip which is mostly a clone of the
Z80-SIO also.
Intel 8274?
(maybe to give the Intel world acess to a usable USART
to this time)
But:
I can't find a datashet for the uPD7201C using google or the usual
suspects, can someone help out here? I think possibly this isn't just a
I have an NEC databook containign this device, and I can type in the
piunout if you don't find it anywhere else. Let me know..
