PIC18F85J90 FAMILY

GUIDELINES FOR GETTING
STARTED WITH PIC18FJ
MICROCONTROLLERS
2.1
Basic Connection Requirements
Getting started with the PIC18F85J90 family family of
8-bit microcontrollers requires attention to a minimal
set of device pin connections before proceeding with
development.
The following pins must always be connected:
All VDD and VSS pins
All AVDD and AVSS pins, regardless of whether or
not the analog device features are used
MCLR pin
ENVREG (if implemented) and VCAP/VDDCORE pins
These pins must also be connected if they are being
used in the end application:
PGC/PGD pins used for In-Circuit Serial
Programming (ICSP) and debugging purposes
(see Section 2.5 “ICSP Pins”)
OSCI and OSCO pins when an external oscillator
source is used
Additionally, the following pins may be required:
VREF+/VREF- pins are used when external voltage
reference for analog modules is implemented
The minimum mandatory connections are shown in
FIGURE 2-1:
RECOMMENDED
MINIMUM CONNECTIONS
Note:
The AVDD and AVSS pins must always be
connected, regardless of whether any of
the analog modules are being used.

C7: 10
F, 6.3V or greater, tantalum or ceramic
R1: 10 k
R2: 100 to 470
Note 1:
explanation of ENVREG pin connections.
2:
The example shown is for a PIC18F device
with five VDD/VSS and AVDD/AVSS pairs.
Other devices may have more or less pairs;
adjust the number of decoupling capacitors
appropriately.
