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

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.
