Happy New Year to all....

Currently, i am still using pic16f84a for my project due to smaller size and no special task require. However the only problem is limited I/O. I also plan to migrate to pic16f628 soon. I/O still a problem for me. I have gone through some article to expand I/O however it is very limited. Is there any way to increase it to 32 or 64 ? How ?

Thx..
