PIC18F8527

Support summary

• Programming - Yes
• Debugging provisions - Yes

ICSP Connection

All VSS and VDD pins must be connected. Even if one of these pins is not connected, programming may fail.

LVP Limitations

Since NSDSP is a Low-Voltage Programmer (LVP), it can only program PIC devices if LVP configuration bit is enabled. Fresh (unprogrammed) devices have LVP bit set and therefore they can be programmed. It is impossible to disable LVP bit during LVP programming, but if the device has been previously programmed with HVP programmer, the LVP bit may have been disabled.

When brown-out is enabled with BOREN configuration bit, LVP is only possible when the VDD voltage is above the brown-out threshold.

These limitations may be avoided with High-Voltage Programming (HVP), however NSDSP requires an external circuit for HVP.

Debugging

NSDSP firmware contains all the necessary provisions for debugging PIC18F8527 and may be debugged when debugging software becomes available.
