PIC24FXXKAXXX
1.0 DEVICE OVERVIEW
This document defines the programming specifications
for the PIC24FXXKAXXX family of 16-bit micro-
controller devices. This is required only for developing
programming support for the PIC24FXXKAXXX family.
Users of any one of these devices should use the
development tools that are already supporting the
device programming.
The programming specifications are specific to the
following devices:
• PIC24F08KA101
• PIC24F16KA101
• PIC24F08KA102
• PIC24F16KA102
• PIC24F04KA200
• PIC24F04KA201
2.0 PROGRAMMING OVERVIEW
OF THE PIC24FXXKAXXX
FAMILY
This section describes the two methods of
programming the PIC24FXXKAXXX family of devices:
• In-Circuit Serial Programming™ (ICSP™)
• Enhanced In-Circuit Serial Programming
(Enhanced ICSP)
The ICSP programming method is the most direct
method for programming the device. However, it is also
the slower of the two methods. It provides native,
low-level programming capability to erase, program,
and verify the device.
Section 3.0 “Device Programming – ICSP” describes
the ICSP method.
The Enhanced ICSP method is a faster method, which
takes advantage of the programming executive as
illustrated in Figure 2-1. The programming executive
provides the necessary functionality to erase, program
and verify the device through a command set. The com-
mand set allows the programmer to program the
PIC24FXXKAXXX devices without having to deal with
the low-level programming protocols of the device.
Section 4.0 “Device Programming – Enhanced
ICSP” describes the ICSP method using the
programming executive.

2.1 Power Requirements
All devices in the PIC24FXXKAXXX family are
3.3V supply designs. The core, the peripherals and the
I/O pins operate at 3.3V. The device can operate from
1.8V to 3.6V.
2.2 Entering Programming Mode
Overview
There are two methods of entering the Programming
mode (either ICSP or Enhanced ICSP):
• Low-Voltage ICSP Entry
When the MCLR
/VPP/RA5 pin is used as MCLR by
applying V
SS on MCLR (low-voltage entry), the
device gets reset, and on applying the Program-
ming mode entry sequence on the PGCx and
PGDx pins, the device enters the Programming
mode.
• High-Voltage ICSP Entry
To enter the Programming mode, if the MCLR
function of the MCLR/VPP/RA5 pin needs to be
disabled or is already disabled, a voltage V
IHH
should be applied on VPP (high-voltage entry).
This is equivalent to applying V
SS on MCLR; the
device gets reset. On applying the Programming
mode entry sequence on PGCx and PGDx pins,
the device enters the Programming mode.
