PLMS-OziPic'er Issue 2.Microchip PIC programmer Hardware

designed forNigel Goodwin's

WinPicProg Software.Suits common 8, 18, 28, 40 Pin PIC's

Option to eliminate using a 40 pin Aries ZIF if desired.

A narrow socket is fitted inside the wide socket. The wide socket must have its tie bars cut off to be able to slip the narrow 28pin (or 2x20pin header sockets) inside it, see photo. This enables wide and narrow Pic's to be programmed without a ZIF socket. Remove or drill out unused socket pins to make the PIC's insert

il

Features:This circuit is an alternative to the many parrallel port PIC programmers that use the 7407 or 7405 type buffers.The 74HC14 buffer is used because of easier availability in some countries ( idea from Gary Aylward's programmer ). It is a Schmitt trigger type which has very good switching performance. In Circuit Programming (ICP) is included, Q6 performs a reset pulse just as VPP is switched to the target PIC to ensure the pic oscillator is stopped. Regulator for VPP is adjustable to trim out losses across the circuit and obtain the correct voltage at the PIC.

NOTES:

74HC14 power is pin 14 to Vcc, Pin 7 to GND.

All resistors are 1/4.All caps are 16V or better unless marked.Use 35V for C1 if exceeding 16V AC onpower supply.

* Check pinouts & re-orientate.

PIC placement (same as P16PRO by B.Dobaj).40 Pin - Top of sockets. 28 Pin - Top of sockets.20 Pin - Bottom of sockets.18 Pin - Bottom of sockets.8 Pin - Pin 1 of PIC to pin 3 of the socket .
