dsPIC33F/PIC24H
1.0 DEVICE OVERVIEW
This document defines the programming specification
for the dsPIC33F 16-bit Digital Signal Controller (DSC)
and PIC24H 16-bit Microcontroller (MCU) families. This
programming specification is required only for those
developing programming support for the dsPIC33F/
PIC24H family. Customers using only one of these
devices should use development tools that already
provide support for device programming.

2.0 PROGRAMMING OVERVIEW
OF THE dsPIC33F/PIC24H
There are two methods of programming the dsPIC33F/
PIC24H family of devices discussed in this
programming specification. They are:
• In-Circuit Serial Programming™ (ICSP™)
programming capability
• Enhanced In-Circuit Serial Programming
The ICSP programming method is the most direct
method to program 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 chip.
The Enhanced ICSP protocol uses a faster method that
takes advantage of the programming executive, as
illustrated in . The programming executiveFigure 2-1
provides all the necessary functionality to erase,
program and verify the chip through a small command
set. The command set allows the programmer to
program the dsPIC33F/PIC24H Programming
Specification devices without having to deal with the
low-level programming protocols of the chip.
FIGURE 2-1: PROGRAMMING SYSTEM
OVERVIEW FOR
ENHANCED ICSP™
This specification is divided into major sections that
describe the programming methods independently.
Section 3.0 “Device Programming – Enhanced
ICSP” describes the Enhanced ICSP method.
Section 5.0 “Device Programming – ICSP”
describes the ICSP method.
2.1 Power Requirements
All devices in the dsPIC33F/PIC24H family are dual
voltage supply designs: one supply for the core and
another for the peripherals and I/O pins. A regulator is
provided on-chip to alleviate the need for two external
voltage supplies.
All of the dsPIC33F/PIC24H devices power their core
digital logic at a nominal 2.5V. To simplify system
design, all devices in the dsPIC33F/PIC24H
Programming Specification family incorporate an
on-chip regulator that allows the device to run its core
logic from VDD.
The regulator provides power to the core from the other
VDD pins. A low-ESR capacitor (such as tantalum) must
be connected to the VCAP pin (Figure 2-2). This helps
to maintain the stability of the regulator. The
specifications for core voltage and capacitance are
listed in Section 8.0 “AC/DC Characteristics and
Timing Requirements”.

2.2 Program Memory Write/Erase
Requirements
The program Flash memory on the dsPIC33F/PIC24H
has a specific write/erase requirement that must be
adhered to, for proper device operation. The rule is that
any given word in memory must not be written without
first erasing the page in which it is located. Thus, the
easiest way to conform to this rule is to write all the data
in a programming block within one write cycle. The
programming methods specified in this document
comply with this requirement.
2.3 Pins Used During Programming
The pins that are used for programming are listed in
Table 2-1.
TABLE 2-1: PINS USED DURING PROGRAMMING
Note 1: These are typical operating voltages. Refer
to TABLE 8-1: “AC/DC Characteristics
and Timing Requirements” for the full
operating ranges of VDD and VCAP.
2: It is important for the low-ESR capacitor to
be placed as close as possible to the V
CAP
pin.

Note: A program memory word can be
programmed twice before an erase, but
only if (a) the same data is used in both
program operations or (b) bits containing
‘1’ are set to ‘0’ but no ‘0’ is set to ‘1’.
Note: Refer to the specific device data sheet for
complete pin diagrams of the dsPIC33F/
PIC24H devices.

dsPIC33F/PIC24H PROGRAMMING SPECIFICATION
2.4 Memory Map
The program memory map extends from 0x0 to
0xFFFFFE. Code storage is located at the base of the
memory map and supports up to 88K instructions
(about 256 Kbytes). Table 2-2 shows the program
memory size and number of erase and program blocks
present in each device variant. Each erase block or
page contains 512 instructions and each program block
or row, contains 64 instructions.
Locations 0x800000 through 0x800FFE are reserved
for executive code memory. This region stores the
programming executive and the debugging
executive. The programming executive is used for
device programming and the debug executive is
used for in-circuit debugging. This region of memory
cannot be used to store user code.
Locations 0xF80000 through 0xF80017 are reserved
for the device Configuration registers.
Locations 0xFF0000 and 0xFF0002 are reserved for
the Device ID Word registers. These bits can be used
by the programmer to identify which device type is
being programmed. They are described in Section 7.0
“Device ID”. The Device ID registers read out
normally, even after code protection is applied.
Figure 2-3 illustrates the memory map for the
dsPIC33F/PIC24H family variants.
