What chip is an RWA828

1

I got a main board out of a mini grand - dead as a post - and it’s got a CPU chip on it labelled RWA828 (see picture). The chip has got clock running but nothing else - no address or data traffic between it and any RAM and ROM.

Can’t find anything about it - would like to get my hands on a data sheet

Anyone on his forum know what it is of has details about it? I would like to have a closer look why it is not running and what needs to be done for a reset - but I need data sheet for that :frowning:

Looks like you might have to buy 10, but here you go:

I couldn’t find a datasheet, but I bet DSYK would be willing to send you one.

Ouch! No original pics of the chip, and a quite low price. That’s a little bit smelly…
