ARM7+4UART+FLAHS?

Started by James Dabbs April 12, 2005
Is there a FLASH ARM7 uC that has 4 UARTS in it?

An Engineer's Guide to the LPC2100 Series

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'm using the philips 16C554DBIA. Still in prototyping but so far so
good.

Which external quad UART ? I have had issues with the Texas
Instruments
TL16C754BPN connected to an LPC2292.

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?
