2.3 Application Header
2.3.1 Backward compatibility with SF100
The SF600 and SF600Plus pin header assignment has been changed versus the SF100 in
order to support the new Serial Flash features like Quad IO and to be compatible with
others DediProg development tools like EM100pro SPI Flash emulator and Backup Boot
Flash tools. If your application has been designed for the SF100, DediProg is providing
with the SF600 and SF600Plus an adaptor to be backward compatible.
2.3.2 Application Universal Header
For new application design, DediProg strongly recommend to implement the universal
Header so you can benefit of all the development tools available and future features of
the Serial Flash and controllers.
- One or two Serial Flash programming
- Single, dual and Quad IO programming
- Controller Reset mode

It is recommended to keep the Header 2*6 even if some signals are unused (Vpp, CS2,
Hold, Wp, reset). The header will stay compatible with the female connector supplied
by default with the SF600 and SF600Plus.
Pin 11 can be used as insertion mistake proof pin. To support this protection of wrong
insertion, the pin 11 has to be cut in the application and the corresponding hole of the
cable connector must be filled accordingly.
2.3.3 Pin Header pitch
The default cable and female connector provided with SF600 and SF600Plus is a
2.54mm pitch.
For space saving reason, you may decide to implement a 1.27mm pitch connector on
your application board. DediProg proposes an adaptor board to convert from 2.54mm
to 1.27mm.
