Hi

I finished my project using (4) 12CE674 JW windowed chips. Everything worked
great. I am using the internal master clear and internal rc no clockout, code
protect off. I programmed a OTP chip and the code doesn't work like the JW.

I originally thought it was getting stuck in a loop. It ran the first serial
LCD output, but the delay of 1 second actually took a approx 70 seconds. It
must bo doing something right because it is outputting at 9600 baud to the
lcd, but everything else is slow.

The LCD displays the ad input very fast with the JW chip, but the OTP it
takes 20 seconds to display a change in the a to d.

I programmed 4 12CE674 OTP chips and they all worked the same. I then re
programmed all 4 JW chips and the code worked fine.

What could be the difference between the JW and the OTP. The part numbers on
the OTP is 12CE674    P04   HBP   9917.

I thought I might have a low speed chip, but why would the serial LCD output
work?

What in the heck is going on?

Thanks

Jon
