ISP connector
PICmicro
This interface corresponds with Microchip application notes
TB013, TB017, TB016: How to Implement ICSP
PIC16CXXX OTP (PIC12C5XX OTP)(PIC16F8X Flash) MCUs.
These application notes describes requirement for target
system
programmer.
Following signals are use for In-system programming of
PICmicro
When PICmicro
driven to approximately 12 V. Therefore, the target system
must be isolated from this voltage provided by programmer.
RB6 and RB7 signals are used by the PICmicro
programming, therefore target system mustn’t affect these
signals during In-system programming to avoid programming
errors.
Marginal verify is used after programming. Programmer must
verify the program memory contents at both minimal and
maximal power supply, therefore VDD pin of PICmicro
be isolated from rest of target system during programming.
B+K PRECISION’s recommended circuit:
Note: External reset circuit is necessary only if VDD power-up
slope is too slow.
