RoHS Compliant
Microchip has converted all of its standard
production from tin-lead (SnPb)-plated product
packaging to lead-free (Pb-free) product
packaging across the entire portfolio of
PIC® microcontrollers, dsPIC® digital signal
controllers, serial EEPROMs, stand-alone
analog and other devices. All standard product
is now shipped with matte tin (Sn) plating and
all products are RoHS-compliant. This enables
our customers to achieve early compliance
with new regulations around the world such as
the European Union Restrictions on Hazardous
Substances in Electrical and Electronic
Equipment (RoHS) directive.

The Capability You Need
16-bit Microcontroller (MCU) Portfolio
Are cost or performance important considerations for your next
design? PIC24 MCUs offer the variety of peripherals, memory
sizes and packaging choices you have come to expect from our
8-bit products. Microchip offers two compatible Flash-based
16-bit PIC24 MCU families. The 16 MIPS PIC24F family is
designed for cost-sensitive applications. The 40 MIPS PIC24H
family is designed for high performance applications. Both
families have the same instruction set, share basic peripherals,
have common pinouts and use the same tools for development.
The PIC24 families are compatible with dsPIC DSCs for easy
migration when additional performance or DSP capability is
required.
16-bit Digital Signal Controller (DSC)
Portfolio
Are you looking to add DSP capability to your application?
DSCs blend the features of both MCUs and DSPs into a
single-chip solution enabling you to add DSP features to
your embedded application. Microchip offers two compatible
Flash-based 16-bit DSC families. The 30 MIPS dsPIC30F
family is designed for applications where 5V operation is
important, and the 40 MIPS dsPIC33F family is suited for
applications preferring 3.3V or need more on-chip memory.
Both DSC families and the PIC24 families have the same
base instruction set (DSCs add DSP instructions), share basic
peripherals, have common pinouts and use the same tools for
development.
Optimized C Compiler:
Supporting the PIC24 MCU and dsPIC
DSC families, Microchip’s 16-bit
architecture was designed to optimize
C language code size. The architecture
was co-developed by compiler writers
who emphasized the need for an
orthogonal instruction set, many general-
purpose registers, powerful indirect
with offset addressing and a software
stack. Now you can achieve leadership
code size in applications, helping your
project team hit schedule and code size
targets. Reduced code size provides the
opportunity to use a smaller memory
device, spend less time optimizing code
size and respond to those marketing
requests for “just one more feature.”

Looking to Add DSP?
If you are one of the many MCU users
looking to add DSP features to your
embedded design, the dsPIC DSCs make
the process easy and straightforward.
The dsPIC DSC retains an MCU look and
feel from the architecture to the tools
you use for development. If you don’t
have the time to become immersed in
DSP technology, you can use one of
the many libraries developed by DSP
experts. Or you can use the available
graphical tools to develop digital filters.
For DSP experts, Microchip includes the
attributes that are typical of true DSPs
in this class: dual 40-bit accumulators,
single cycle 16x16 MAC, dual operand
fetches, saturation and rounding modes,
and zero overhead looping. This is not
simply a MCU with a MAC attached as
an afterthought.
Flexible Flash:
All of Microchip’s 16-bit products employ
flexible and secure Flash memory. You can
use the Flash memory to store programs
or data tables. Additionally, all devices
can self-program their own Flash memory
in a finished product. The PIC24H and
dsPIC DSC families offer advanced security
features that enable you to secure your
base code and allow OEMs to “customize”
the application or alternatively enhance
work with encrypted data.
Powerful 16-bit CPU:
The PIC24 MCU and the dsPIC DSC
families execute most instructions in
one cycle. Interrupts are serviced quickly
and are deterministic. Bit manipulation
is accomplished in a single cycle. Add
latest generation features, such as zero
overhead looping, single-cycle multiply
and a barrel shifter, and you have the
most powerful 16-bit MCU for your
embedded control designs.
Migration Options:
Once you have designed our 16-bit
products into your application, future
designs are simplified. You can select
from a broad range of memory, pin
count, peripheral, performance and price
options without changing architecture
or development tools. The pinout,
software and tool compatibility helps
make stepping to different performance
or memory points very straightforward.
This is also beneficial if you design
in an environment of rapidly evolving
requirements.
Considering a 32-bit MCU?
Has your current MCU run out of steam?
Microchip’s performance-oriented 16-bit
solutions can significantly outperform
low cost 32-bit controllers for many
MCU applications. Why abandon 16-bit
deterministic performance, native bit
manipulation, fast fixed-latency interrupts
and low cost tools to gain inferior 32-bit
performance? Many engineers using 32-bit
devices have reverted to Microchip’s 16-
bit products after discovering performance
issues during the course of their design.

Highly Cost-Effective PIC24F 16-bit MCUs
With 16 MIPS performance and an extensive peripheral set, the
PIC24F MCUs are a highly cost-effective solution for all but the
most demanding 16-bit applications. The PIC24F also offers an
easy migration path for design engineers whose applications
have outgrown the performance offered by 8-bit MCUs.
Versatile 5 Volt dsPIC30F DSCs
The 30 MIPS dsPIC30F family is developed for applications
that benefit from a wide operating voltage (2.5 to 5.5 volts),
extremely low standby current, integrated EEPROM, and for those
that prefer 5V operation due to system considerations.
Highest Performance PIC24H 16-bit MCUs
For more demanding applications, the PIC24H offers 40 MIPS
performance, more memory and additional peripherals. The
PIC24H family adds up to 2 CAN communication modules, and
a user-selectable 10/12-bit Analog-to-Digital (A/D) converter.
Integrated Direct Memory Access (DMA) between peripherals and
dual-port RAM provides zero overhead data transfers, optimizing
CPU throughput.
High Performance, Cost Effective 3.3 Volt
dsPIC33F DSCs
The 40 MIPS dsPIC33F family is developed for high performance
embedded control applications. Compared to the dsPIC30F
family, the dsPIC33F family offers larger RAM and Flash memory
options and adds DMA.
