PIC24FJ64GA004 FAMILY
2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC24FJ64GA004 family of
16-bit microcontrollers requires attention to a minimal
set of device pin connections before proceeding with
development.
The following pins must always be connected:
 All V
DD and VSS pins
(see Section 2.2 “Power Supply Pins”)
 All AV
DD 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”)
 ENVREG/DISVREG and V
CAP/VDDCORE pins
(PIC24F J devices only)
(see Section 2.4 “Voltage Regulator Pins
(ENVREG/DISVREG and V
CAP/VDDCORE)”)
These pins must also be connected if they are being
used in the end application:
 PGECx/PGEDx 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:
 V
REF+/V REF- pins 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: 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 kΩ
R2: 100Ω to 470Ω
Note 1: See Section 2.4 “Voltage Regulator Pins
(ENVREG/DISVREG and V
CAP/VDDCORE)”
for an explanation of the ENVREG/DISVREG
pin connections.
2: The example shown is for a PIC24F device
with five V
DD/VSS and AV DD/AVSS pairs.
Other devices may have more or less pairs;
adjust the number of decoupling capacitors
appropriately.
