Is there a dumb UART readily available?
 
I am designing a box that sends out serial telemetry based on 8 switches
being ON or OFF. A serial interface looks like a good way to do it. I
don't need interrupts, I don't need FIFOs, I don't need modem status
bits, I don't need none of that stuff.
 
I would rather not bump the level of complexity up several notches by
requiring a microcontroller (and its firmware) just to initialize the
UART speed and so forth. Is there a really dumb UART that can come up in
a known state and just shovel data? National Semiconductor's 16450/16550
data sheet lists the default state of all registers except the Divisor
Latch Register, which is the most important one for my application.
It would be nice if I could simply power it up and strobe it when
data is ready.
 
Maybe I should be looking at the 65xx family?
