The PIC24F16KL402 family adds an entire range of
economical, low pin count and low-power devices to
Microchip’s portfolio of 16-bit microcontrollers. Aimed
at applications that require low-power consumption but
more computational ability than an 8-bit platform can
provide, these devices offer a range of tailored
peripheral sets that allow the designer to optimize both
price point and features with no sacrifice of
functionality.
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 12 Mbytes (program
space) and 64 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
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 PIC24F16KL402 family
incorporate a range of features that can significantly
reduce power consumption during operation. Key
features 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
The PIC24F16KL402 family offers 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.
• 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
reference 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.
1.1.4 EASY MIGRATION
Regardless of the memory size, all the 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 helps in migrating to the next larger
device. This is true when moving between devices with
the same pin count, or even jumping from 20-pin or
28-pin devices to 44-pin/48-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.
