2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC24FJ128GC010 family
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 VDD and VSS pins
(see Section 2.2 “Power Supply Pins”)
• All analog power pins (AVDD, SVDD, AVSS and
SVSS), regardless of whether or not the analog
device features are used
(see Section 2.2 “Power Supply Pins”)
• The USB transceiver supply, VUSB3V3, regardless
of whether or not the USB module is used
(see Section 2.2 “Power Supply Pins”)
• MCLR pin
(see Section 2.3 “Master Clear (MCLR) Pin”)
• VCAP pin
(see Section 2.4 “Voltage Regulator Pin (VCAP)”)
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:
• Any voltage reference pins used when external
voltage reference for analog modules is
implemented (AVREF+/AVREF-, CVREF+/CVREF-,
DVREF+ and SVREF+/SVREF-)
Note:
All analog power supply and return pins
must always be connected, regardless of
whether any of the analog modules are
being used.
The minimum mandatory connections are shown in
Figure 2-1.

See Section 2.4 “Voltage Regulator Pin
(VCAP)” for details on selecting the proper
capacitor for VCAP.
The example shown is for a PIC24F device
with five power and ground pairs (including
analog and USB). Other devices may have
more or less pairs; adjust the number of
decoupling capacitors appropriately.
See Section 19.1 “Hardware Configura-
tion” for details on connecting the pins for
USB operation.
C1 is optional, see Section 2.3 “Master
Clear (MCLR) Pin” and Section 2.5 “ICSP
Pins” for more information.
