'Replacing 16C84 with an 12C508'
i have developed a small circuit with an 16C84, i need only 1 input and 1
output, and 200 bytes of program memory. Can i replace the 16C84 with an
12C508, it is much cheaper. Can i use my David Tait programmer for the
Greetings from Germany,
may i ask what sort of code you are thinking of putting onto that pic?
I am planning to replace a 16F84 with a 12C508 as well. I was just wondering
if is possible to use a programmer that was made especially made for the
16f84 (kit 84, kitsrus.com)?
I was think that I all I had to was simply map the proper pins made for the
16f84 down to the 12C508?
I have the pdf schematic for the kit if anybody wants to help me.

you only need 4 jumpers on the solder side of the board.
but you may also need:

So if I am not wrong then the following is a list between what pins on the
18 pin pic16f84 correspond to the 508/509:
====================== F84 | 508/509 |
VDD (5V Pulse) 14 | 1 |
VPP (13V Pulse) 4 | 4 | <- MCLR*
RB7 13 | 7 |
RB6 12 | 6 |
GND 5 | 8 |
Somebody please correct my if I am wrong! Most of the pins make sense.
BTW, has anybody done such a replacement (F84 -> 508/509) in burning pics
and had it worked?
