1.0 DEVICE OVERVIEW
This document defines the programming specifications
for the PIC24FXXKA1XX/FVXXKA3XX family of 16-bit
microcontroller devices. This is required only for
developing programming support for the
PIC24FXXKA1XX/FVXXKA3XX 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:
2.0 PROGRAMMING OVERVIEW
OF THE
PIC24FXXKA1XX/FVXXKA3XX
FAMILY
This section describes the two methods
of programming the PIC24FXXKA1XX/FVXXKA3XX
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 a 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
command set allows the programmer to program the
PIC24FXXKA1XX/FVXXKA3XX 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
Devices in the PIC24FXXKA1XX and
PIC24FXXKA3XX families 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.
Devices in the PIC24FVXXKA3XX families are 5.0V
supply designs. The core, the peripherals and the I/O
pins operate at 3.3V. The device can operate from 2.0V
to 5.5V; an internal regulator operates the core logic at
3.25V.
Table 2-1 provides the pins that are required for
programming, which are indicated in Figure 2-3. Refer
to the appropriate device data sheet for complete pin
descriptions. Note that all power supply and ground
pins must be connected appropriately for
programming.
