PIC24F16KA102 FAMILY
2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC24F16KA102 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 âPower Supply Pinsâ)
⢠All AVDD and AVSS pins, regardless of whether or
not the analog device features are used
(see Section 2.2 âPower Supply Pinsâ)
⢠MCLR pin
(see Section 2.3 âMaster Clear (MCLR) Pinâ)
⢠VCAP pins
(see Section 2.4 âVoltage Regulator Pin (VCAP)â)
These pins must also be connected if they are being
used in the end application:
⢠PGECx/PGEDx pins used for In-Circuit Serial
Programming⢠(ICSPâ¢) and debugging purposes
(see Section 2.5 âICSP Pinsâ)
⢠OSCI and OSCO pins when an external oscillator
source is used
(see Section 2.6 âExternal Oscillator Pinsâ)
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.

See Section 2.4 âVoltage Regulator Pin
(VCAP)â for explanation of VCAP pin
connections.
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.
Some PIC24F K parts do not have a
regulator.
