MSP430
Value Line
LaunchPad Development Kit
Introduction
As
applications continue to advance, 8-bit
microcontrollers are struggling to
meet
the growing demand for higher performance and
ultra-low power to support
evolving
product designs. Texas Instruments introduced the
affordable 16-bit
MSP430? MCU Value
Line to meet the
changing market
dynamics and requirements
faced by
typical low-cost 8-bit MCU developers. Taking the
next step in providing a
low-cost
solution to the shortcomings of 8-bit MCUs, TI
created the MSP430 MCU
Value Line
LaunchPad development kit to jump start
application designs and provide
a low-
cost tool for developers of all experience levels.
This overview will provide an
introduction to the features and
functionality of LaunchPad as well as everything
included in the $$4.30 kit.
As the number of competitors grow and
the time for taking products to market
shrinks, the microcontroller (MCU)
industry is being stretched by two opposing, but
equally strong vectors. The growing
demand for higher performance and ultra-low
power functionality is matched only by
an aggressive need for lower and lower price
points. This is especially clear in
low-cost applications that utilize 8-bit MCUs. To
increase performance without breaking
the bank, developers of low-cost 8-bit MCUs
must migrate to higher performance
16-bit MCUs that are available at affordable price
points.
In high volume and
quick turnover markets such as consumer and
personal
electronics, the need for a
highly differentiated MCU, while maintaining
aggressive
price points, is a constant
struggle. For instance, the market for 3D glasses
has
exploded in the recent months, both
on the big and small screen. As this market trend
moves up and to the right, developers
are hard at work in creating technological
solutions that provide a unique and
immersive experience while remaining affordable.
By providing more affordable solutions,
developers hope to minimize the risks and
barriers associated with new and fast
moving markets.
For many, this barrier
to success is prohibited by a limited MCU core.
Many
developers of 8-bit MCUs have
completely exhausted the full capabilities of
their
MCU due to limited data
throughput and inefficient interfacing with higher
resolution
analog and digital
peripherals. To enable increased functionality and
improve feature
sets of existing
projects, developers must migrate to higher
performance 16-bit
MCUs.
The
MSP430 MCU Value Line series provides a migration
path for many of
these constrained
8-bit MCU developers. At no additional cost, the
affordable
MSP430 MCU Value Line
devices offer a 16-bit architecture, higher
precision timers
and improved
peripheral integration and interfacing, enabling
improved performance
and lower power
consumption. The implementation of 16-bit MCUs
enable up to 10
times improved
performance and 10 times lower power when compared
to many
low-cost 8-bit applications.
Currently, the MSP430 MCU Value Line series offers
27
ultra-low power 16-bit devices that
offer varying levels of analog integration,
communication modules and package
types. At 100K unit volumes, MSP430 MCU
Value Line devices start at just $$0.25
USD, ensuring that developers do not have to
sacrifice price for improved
performance. Additionally, the MSP430 MCU Value
Line
series will continue to grow to
more than 100 devices through the second half of
roadmap will introduce higher memory
sizes, more package options and
additional integrated analog and
digital peripherals.
To make the
transition from 8- to 16-bit MCUs more seamless,
Texas
Instruments (TI) listened to the
requirements of developers and created the new
MSP430 MCU Value Line LaunchPad
development kit. Furthering the commitment
to add performance and value to MCU
designs with the MSP430 MCU Value Line, TI
introduced LaunchPad to lower the
barrier of entry for developers new to 16-bit
architectures, or
those new
to MCU design, in general. The LaunchPad kit is
TI’s
simple, yet thorough, introduction
to 16-bit MCU development, offering all of the
hardware and software a developer needs
to get started for just $$4.30 USD. Within
minutes of opening the LaunchPad kit,
users can begin interfacing with pushbuttons,
LEDs and the on-chip peripherals of the
MSP430 MCU Value Line devices. See
Figure 1 below:

For
just
$$4.30,
the
LaunchPad
kit
includes
a
development
board
with
an
integrated USB-powered flash emulation
tool for programming and debugging any of
the
existing
MSP430
MCU
Value
Line
devices.
Any
MSP430G2xx
MCU
in
a
DIP
package can
be dropped into the DIP target socket of
LaunchPad, which allows easy
evaluation
of any MSP430 MCU Value Line device. The flexible
target socket allows
developers to remove their freshly
programmed and debugged MSP430G2xx MCU to
be plugged into a custom breadboard or
PCB so that customers are not constrained to
the form factor of the LaunchPad board.
Alternatively, developers can use LaunchPad
as a standalone system, by leaving the
MSP430G2xx device plugged into the board to
leverage on-board and programmable push
buttons and LEDs. Additionally, every pin
of the MSP430G2xx device is fully
accessible, allowing easy interfacing of external
components or custom daughter cards.
Also provided in the kit are free,
downloadable software compilers and
debuggers including TI’s own
eclipse-
based Code Composer Studio?
version 4 and
IAR Embedded Workbench
Kickstart. These independent development
environments
(IDEs) are full featured
and are completely compatible with LaunchPad and
the
MSP430 MCU Value Line devices
available today. This complements the hardware
features of the LaunchPad board by
providing a complete software component as well.
Using either IDE, users can then
leverage MSP430 MCU code examples, open source
projects and other free online
resources, which can be accessed on
LaunchPad’s Wiki
page, /launchpadwiki.
The unlimited access to the LaunchPad
Wiki promotes collaboration and simple
sharing of solutions and ideas, making
LaunchPad a complete development
environment. This active and growing
online community supplements the hardware
and software components of the
LaunchPad package and provides instant support,
projects and helpful hints that will be
shared through the Wiki pages and E2E?
forums.
To fully benefit
from 16-bit architecture and ultra-low power
performance, the
MSP430 MCU Value Line
series and LaunchPad development kit offers a
complete
and simple introduction to
quicken developers’
time to market. By
providing 16-bit
performance at 8-bit
price points, and complete development tools for
just $$4.30, TI
would like to welcome
both new and experienced users to the world of
high
performance and affordable MCU
development.
