Portable PIC Programmer

It's portable!

Unlike previously published designs, this new PIC programmer can be battery powered for portable use. It can also program all the latest 8-pin and 18-pin devices, including the PIC16F628A and PIC12F629.

Another important addition is power supply current limiting. This feature makes it virtually impossible to destroy a PIC, even if it is accidentally reversed in the programming socket (great for instructional use)!

We've also included rudimentary in-circuit programming support. A five-way header on the programmer can be connected to your prototyping board for in-circuit reprogramming capability. This means that there's no need to unplug the PIC (which may be difficult to get to) each time you want to test a change to your code.

Finally, a second header has been included for connection to a user-wired programming adapter. This provides a means of programming the 24CXX family of serial EEPROMs, as well as 28-pin and 40-pin (16F87X series) PICs.

Main Features
  • Battery (on-board) or plugpack powered
  • Programs PIC16F84/A, 16F627/A, 16F628/A, 12F629 & 12F675 micros
  • Programs PIC16F87X & 24CXX EEPROMS with user-wired adapters
  • Serial port connected (eliminates parallel port cabling issues)
  • Reverse PIC protection
  • Supports in-circuit programming (limited, see text)
  • Recommended software runs on Win9x, Me, NT4, 2000 & XP
