suggestions please We use Cirrus' ARM9 9312 on a board, which is big( 28mm square ).
it has built in MAC it has 3 serial ports, though 2 are a bit short on handshake lines. it has built-in LCD graphics
we have so far only used big TQFP ram/flash chips with it.
it has a big brother the 9315 which supports a PCMCIA interface, but we would need to change the artwork to use it.
that's by way of background...
===================================================
have following pair of customer requirements:
Small board:
1 Ethernet 4 if poss UARTs no graphics Doesn't need Linux or anything - but needs good dev + debug environment Large board 2 Ethernet ( need only be 10 meg ) 1/4 VGA LCD no serial ports in particular. must support Linux or something for display drivers etc. ====================================================Now I COULD do large board with the cirrus device, and add a 2nd Enet via USB, PCMCIA or knife-and-fork ( memory-mapped or whatever )
I was thinking of something like the AT91RM9200 for the small board. It's blatant overkill, but it has all the boxes ticked. I need to work out what a minimum system including it might be. Oh, and the price :-)
hmmm - see
there is an example cct for this interfacing it to the Epson S1D13806, which seems to have gone obsolete, but the S1D13506 looks like a less integrated version, and is still around..
So I COULD use the same CPU... with external graphics... still need to kludge on a 2nd Ethernet though.
===================================================
Can anyone suggest a more integrated solution - where the same technology could be used on both. The customer can wrestle a C compiler, but I am very keen to offer good development and debug facilities to ease the transition.
