PIC18F6XKXX/8XKXX FAMILY
1.0 DEVICE OVERVIEW
This document includes the programming specifications
for the following devices:
2.0 PROGRAMMING OVERVIEW
The PIC18F6XKXX/8XKXX family of devices can be
programmed using the In-Circuit Serial Programming™
(ICSP™) method. This programming specification
applies to the PIC18F6XKXX/8XKXX family of devices
in all package types.
2.1 Hardware Requirements
When programming with the ICSP, the PIC18F6XKXX/
8XKXX family requires two programmable power sup-
plies: one for VDD and one for MCLR/VPP/RG5. Both
supplies should have a minimum resolution of 0.25V.
Refer to Section 6.0 “AC/DC Characteristics Timing
Requirements for Program/Verify Test Mode” for
additional hardware parameters.
2.1.1 LOW-VOLTAGE ICSP™
PROGRAMMING
In Low-Voltage ICSP mode, the PIC18F6XKXX/8XKXX
family can be programmed using a V
DD source in the
operating range. The MCLR
/VPP/RG5 does not have to
be brought to a different voltage, but can instead be left
at the normal operating voltage. Refer to Section 6.0
“AC/DC Characteristics Timing Requirements for
Program/Verify Test Mode” for additional hardware
parameters.
2.2 Pin Diagrams
The pin diagrams for the PIC18F6XKXX/8XKXX family
are shown in Figure 2-1 and Figure 2-2.
