APPENDIX E: PIC16C84

CONVERSION

CONSIDERATIONS

This appendix discusses some of the issues that you

may encounter as you convert your design from a

PIC16C84 to any of the newly introduced devices.

These new devices are:

• PIC16C83

• PIC16CR83

• PIC16C84A

• 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 PIC16C84A 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.
