PIC24F16KL402 FAMILY
2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC24F16KL402 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 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”)
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 2.4 “ICSP Pins”)
• OSCI and OSCO pins when an external oscillator
source is used
(see Section 2.5 “External Oscillator Pins”)
Additionally, the following pins may be required:
• VREF+/VREF- pins are used when external voltage
reference for analog modules is implemented
Note:
The AVDD and AVSS 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.

Note 1:
The example shown is for a PIC24F device
with five VDD/VSS and AVDD/AVSS pairs.
Other devices may have more or less pairs;
adjust the number of decoupling capacitors
appropriately.
