This is revision A of the PIC28 Plug and it is currently a work in progress.

EMDP1 PIC28 Plug (Rev. A)

Table of Contents

Introduction

The PIC28 plug is used to program 28-pin and 40-pin PIC's. This includes the PIC16F64x, PIC16F66x, PIC16C6x, PIC16C7x, PIC16C9x, PIC16F7x, and PIC16F87x. It is likely that MicroChip will add additional processors that adhere to this pin-out as they continue to expand their PIC product line.

The PIC28 identifier is 0000 0000 0010.

The PIC28 back (component) layer.
pic28_front.png
The PIC28 front (solder) layer.
pic28.gal
The PIC28 RS274X `Gerber' file for the pic28 plug artwork (silk screen) layer.
pic28.gbl
The PIC28 RS274X `Gerber' file for the pic28 plug back (component) layer.
pic28.gtl
The PIC28 RS274X `Gerber' file for the pic28 plug front (solder) layer.
pic28.gml
The PIC28 RS274X `Gerber' file for the pic28 plug solder mask layer.
pic28.drl
