PIC24FJ256DA210 FAMILY
1.0
DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
The PIC24FJ256DA210 family enhances on the exist-
ing line of Microchip‘s 16-bit microcontrollers, adding a
new Graphics Controller (GFX) module to interface
with a graphical LCD display and also adds large data
RAM, up to 96 Kbytes. The PIC24FJ256DA210 family
allows the CPU to fetch data directly from an external
memory device using the EPMP module.
1.1
Core Features
1.1.1
16-BIT ARCHITECTURE
Central to all PIC24F devices is the 16-bit modified
Harvard architecture, first introduced with Microchip’s
dsPIC
®
 Digital Signal Controllers (DSCs). The PIC24F
CPU core offers a wide range of enhancements, such
as:
• 16-bit data and 24-bit address paths with the 
ability to move information between data and 
memory spaces
• Linear addressing of up to 12 Mbytes (program 
space) and 32 Kbytes (data)
• A 16-element working register array with built-in 
software stack support
• A 17 x 17 hardware multiplier with support for 
integer math
• Hardware support for 32 by 16-bit division
• An instruction set that supports multiple 
addressing modes and is optimized for high-level 
languages, such as ‘C’
• Operational performance up to 16 MIPS
1.1.2
POWER-SAVING TECHNOLOGY
All of the devices in the PIC24FJ256DA210 family
incorporate a range of features that can significantly
reduce power consumption during operation. Key
items include:
• On-the-Fly Clock Switching: The device clock 
can be changed under software control to the 
Timer1 source or the internal, low-power RC 
oscillator during operation, allowing the user to 
incorporate power-saving ideas into their software 
designs.
• Doze Mode Operation: When timing-sensitive 
applications, such as serial communications, 
require the uninterrupted operation of peripherals, 
the CPU clock speed can be selectively reduced, 
allowing incremental power savings without 
missing a beat.
• Instruction-Based Power-Saving Modes: The 
microcontroller can suspend all operations, or 
selectively shut down its core while leaving its 
peripherals active with a single instruction in 
software.
1.1.3
OSCILLATOR OPTIONS AND 
FEATURES
All of the devices in the PIC24FJ256DA210 family offer
five different oscillator options, allowing users a range
of choices in developing application hardware. These
include:
• Two Crystal modes using crystals or ceramic 
resonators.
• Two External Clock modes offering the option of a 
divide-by-2 clock output.
• A Fast Internal Oscillator (FRC) with a nominal 
8 MHz output, which can also be divided under 
software control to provide clock speeds as low as 
31 kHz.
• A Phase Lock Loop (PLL) frequency multiplier, 
available to the external oscillator modes and the 
FRC oscillator, which allows clock speeds of up to 
32 MHz.
• A separate Low-Power Internal RC Oscillator 
(LPRC) with a fixed 31 kHz output, which provides 
a low-power option for timing-insensitive 
applications.
The internal oscillator block also provides a stable
reference source for the Fail-Safe Clock Monitor
(FSCM). This option constantly monitors the main clock
source against a reference signal provided by the inter-
nal oscillator and enables the controller to switch to the
internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
1.1.4
EASY MIGRATION
Regardless of the memory size, all devices share the
same rich set of peripherals, allowing for a smooth
migration path as applications grow and evolve. The
consistent pinout scheme used throughout the entire
family also aids in migrating from one device to the next
larger, or even in jumping from 64-pin to 100-pin
devices.
The PIC24F family is pin compatible with devices in the
dsPIC33 family, and shares some compatibility with the
pinout schema for PIC18 and dsPIC30. This extends
the ability of applications to grow from the relatively
simple, to the powerful and complex, yet still selecting
a Microchip device.
