[sci.electronics] lowest cost micro for

jfreem@uncecs.edu (Joe Freeman) (02/08/91)

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.
