I've been looking at a couple problems where some type of digital data,
never more than 8 bits wide needs to be converted and run through a
serial port on a computer, at 9600 baud. There is usually some
handshaking involved so a straight uart won't work. What is the cheapest
chip combo that would do the job?
Using quantity one pricing I have come up with.
A) Z8 @ 2.95, 2764 @ 3.95, crystal @ 1.75, Harris 5V->RS232 chip 4.80
$13.35
B) 8748 with software uart @7.95, crystal @ 1.75, Harris chip 4.80
14.50
Can anyone think of anything cheaper?
It probably needs a timer if doing software uart.
