2.0 PROGRAMMING OVERVIEW
The PIC18FXXK80 family of devices can be
programmed using the In-Circuit Serial Programming™
(ICSP™) method. This programming specification
applies to the PIC18FXXK80 family of devices in all
package types.
2.1 Hardware Requirements
When programming with the ICSP, the PIC18FXXK80
family requires two programmable power supplies; one
for VDD and one for MCLR/VPP/RE3. 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 PIC18FXXK80 family
can be programmed using a VDD source in the operat-
ing range. The MCLR/VPP/RE3 pin 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 PIC18FXXK80 family are
shown in Figure 2-1 and Figure 2-2.
