Is that plug n play? And what software would make use of it?

 

The only software needed is for configuration change and for FLASH programming. It will be provided.

 

While looking at the bank switch table I'd say it's safe to assume that is requires 64KB base memory.

 

No. It doesn't require any RAM at all.

 

Does it fin in a 400?

 

Unfortunately, don't.

 

Is it flashable via software or do we need an EPROM programmer?

 

It is flashable.
