Post by thread:Replacing 16C84 with an 12C508

Hello, 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 12C508? Greetings from Germany, Wolfgang Kerner

Hello, 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. Thanks. Sep S.

Hello, 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 | =========================================== http://www.dontronics.com/dt001cha.html thanks Don. =========================================== 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? Later. +--------------------------+ | Sep Seyedi | | -> sepKILLspamhypervr.com | | -> http://sep.2y.net | +--------------------------+
