CONVERSION
CONSIDERATIONS
This appendix discusses some of the issues that you
may encounter as you convert your design from a
PIC16C84 to a PIC16F83 or PIC16F84 device. These
new devices are:
• PIC16F83
• PIC16CR83
• PIC16F84
• PIC16CR84
Some of the issues that may be encountered are:
1. The polarity of the PWRTE configuration bit has
been reversed. Ensure that the programmer has
this bit correctly set before programming.
2. The PIC16F84 and PIC16CR84 have larger
RAM sizes. Ensure that this does not cause an
issue with your program.
3. The MCLR
pin now has an on-chip filter. The
input signal on the MCLR
pin will require a
longer low pulse to generate an interrupt.
4. Many electrical specifications have been
improved. Compare the electrical specifications
of the two devices to ensure that this will not
cause a compatibility issue.
