ARM7+4UART+FLAHS?

2005-04-12 by James Dabbs

Is there a FLASH ARM7 uC that has 4 UARTS in it?

There may be but my current project uses a Philips 2131 with an external
quad uart.

The Atmel AT91SAM7A3 has four UARTs.  There are three fully
functional USARTs and a Debug Unit (I wish Atmel would change
its name).  The Debug Unit is a UART (not USART) with transmit
and receive lines (no control signals).  IIRC it has all of the
features of the UART portion of the standard Atmel USARTs including
the PDC (peripheral data controller).

I think one of the ST variants may.  I was looking at them for a possible 
project but haven't been tracking them very closely since they dropped the 
serial ISP.

Jeff,

I searched the philips website but didn't get any hits on that part #.  I
did find the SC28C94.  Is that the one you're using?

Unless you’re an automotive manufacturer and can buy 1000's of these
you'll NEVER get your hands on any of these...

Anyone can buy the MAC7111MPV40 now. I ordered two some weeks ago,
and they arrived this week. The others in the family are still only available to
large automotive manufacturers.

I am facing problems with 16C554 interfaced to LPC2294.
16C554 initialised to baudrate of 4800.
Getting Chip Selects, getting WR signal but serial data not getting 
out from Transmit pins. Can you suggest any solution ?

2005-11-10 by Bisser Gatchev

Probably your WR signal is ahead of the CS. Check the timing of the LPC and the UART. Try placing a 220pF capacitor between WR and GND. It should delay WR long enough for the UART to start working. We had a similar problem here and that's how we solved it.
