In-System Programming of an
External Target System
The STK500 can be used as a programmer to program AVR devices in other applica-
tions. There are two different ISP connector pinouts available: a 6-pin and a 10-pin
version. Both are supported by STK500.
Figure 6-1.

10-pin ISP Connector Pinout
Select the device to be programmed in the same way as programming a device on the
STK500. The V
CC
of the target application is detected by STK500 and signals are con-
verted into voltage levels suitable for the target system.
Note:
If the other application has its own power supply to VTG, the jumper VTARGET
must be removed before connecting STK500 to the other application. STK500
may be damaged if the VTARGET jumper is not removed.
