I have just developed an application for a PIC16c55. After checking
if worked correctly I decided to blow it onto a OTP device for the
final product. However, I got a fuse error report from the mps16b
program. Exact details bellow:-

Developement EPROM chip :   PIC16C55/JW-S1
Final OTP chip          :   PIC16C55-XT/P

Clocking method         :   8MHz Crystal

I tried to program the OTP to use an HS clock. But it reported that
it had been programmed LP !

Is there something I don't know about these OTP chips. I thought they
are supposed to be able to do everything the EPROM devices are.

Could it simply be that this OTP chip is defective ?

Anyone got any suggestions?

Thanks,

Wayne G Boyd.
