PIC24FV16KM204 FAMILY
1.0 DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
The PIC24FV16KM204 family introduces many new
analog features to the extreme low-power Microchip
devices. This is a 16-bit microcontroller family with a
broad peripheral feature set and enhanced computa-
tional performance. This family also offers a new
migration option for those high-performance applica-
tions which may be outgrowing their 8-bit platforms, but
do not require the numerical processing power of a
Digital Signal Processor (DSC).
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. 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 16 Mbytes (program
space) and 16 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-bit by 16-bit division
• An instruction set that supports multiple address-
ing 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 PIC24FV16KM204 family incor-
porate a range of features that can significantly reduce
power consumption during operation. Key features
include:
• On-the-Fly Clock Switching, to allow the device
clock to be changed under software control to the
Timer1 source or the internal, low-power RC
Oscillator during operation, allowing users 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, to allow
the microcontroller to 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
The PIC24FV16KM204 family offers five different oscil-
lator options, allowing users a range of choices in
developing application hardware. These include:
• Two Crystal modes using crystals or ceramic
resonators.
• Two External Clock (EC) modes offering the
option of a divide-by-2 clock output.
• Two Fast Internal Oscillators (FRCs), one with a
nominal 8 MHz output and the other with a
nominal 500 kHz output. These outputs can also
be divided under software control to provide clock
speed as low as 31 kHz or 2 kHz.
• A Phase Locked Loop (PLL) frequency multiplier,
available to the external oscillator modes and the
8 MHz FRC Oscillator, which allows clock speeds
of up to 32 MHz.
• A separate 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 ref-
erence source for the Fail-Safe Clock Monitor (FSCM).
This option constantly monitors the main clock source
against a reference signal provided by the internal
oscillator and enables the controller to switch to the
internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
