PIC18F47J53 FAMILY
2.0
GUIDELINES FOR GETTING
STARTED WITH PIC18FJ
MICROCONTROLLERS
2.1
Basic Connection Requirements
Getting started with the PIC18F47J53 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
(see Section 2.2 “Power Supply Pins”)
•All AVDD and AVSS pins, regardless of whether or
not the analog device features are used
(see Section 2.2 “Power Supply Pins”)
•MCLR pin
(see Section 2.3 “Master Clear (MCLR) Pin”)
•VCAP/VDDCORE pins (see Section 2.4 “Voltage
Regulator Pins (VCAP/VDDCORE)”)
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
(see Section 2.6 “External Oscillator Pins”)
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.
FIGURE 2-1:
RECOMMENDED
MINIMUM CONNECTIONS
Note:
On 44-pin QFN packages, the AVDD and
AVSS pins must always be connected,
regardless of whether any of the analog
modules are being used. On other pack-
age types, the AVDD and AVSS pins are
internally connected to the VDD/VSS pins.

Note 1:
See Section 2.4 “Voltage Regulator Pins
(VCAP/VDDCORE)” for explanation of
VCAP/VDDCORE 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.
