MSP430 Ultra-Low-Power

Microcontrollers—The Solution

for Battery-Powered Measurement

Product Bulletin Q4-2001

The MSP430 family of ultra-low-

power 16-bit RISC mixed-signal

processors from Texas Instruments

(TI) provides the ultimate solution

for battery-powered measurement

applications. For low-power appli-

cations where both analog and

digital signal processing are

required, the MSP430 line provides

a range of exceptional cost/

performance options. Using its

leadership in both mixed-signal and

digital technologies, TI has created

the MSP430 family which enables

system designers to simultaneously

interface to analog signals, sensors

and digital components while main-

taining unmatched low power.

Applications

When battery life, processing

power and hardware flexibility

are major design concerns, TI's

MSP430 family offers an unbeat-

able combination of features.

The MSP430 family is suitable

for applications such as:

• Utility metering—

gas, water, electric, heat

allocators, thermostats

• Portable instrumentation—

glucose meters, heart-rate

monitors, thermometers,

multi-meters, weight scales

• Intelligent sensing—

security systems, smoke

detectors, electronic tags

The MSP430 line of ultra-low-

power microcontrollers offers

solutions that enable product

ideas to become reality.

Key Features

•Ultra-low-power architecture

extends battery life

- 0.1µA RAM retention

- 0.8µA real-time clock mode

- 250µA / MIPS active

•High-performance analog ideal

for precise measurement

•Modern 16-bit RISC CPU

enables new applications at

a fraction of the code size

•In-system programmable Flash

permits flexible code changes,

field upgrades and data logging

•Complete integrated develop-

ment environment starting

at $49

•Device pricing starting at $0.99

MSP430 Architecture

Using a von-Neumann common

memory address bus (MAB) and

memory data bus (MDB), a 16-bit

RISC CPU, peripherals and flexible

clock system are combined.

Partnering a modern CPU with

modular memory-mapped analog and

digital peripherals, the MSP430 offers

solutions for today’s and tomorrow’s

mixed-signal applications.

Memory Options

• Flash, ROM, OTP versions

(from 1 kB to 60 kB)

• RAM up to 2 kB

Analog Peripherals

•High-performance ADC

•Comparator

•LCD driver

• Supply Voltage Supervisor (SVS)

Digital Peripherals

•USART

•Hardware multiplier

• 16-bit and 8-bit timers

Modern 16-Bit RISC CPU

• Large register file eliminates

accumulator bottleneck

•Optimized for C and

assembler programming

•Compact core design reduces

power and cost

•Up to 8 MIPS of performance

available

The MSP430’s orthogonal archi-

tecture provides the flexibility of

16 fully addressable single-cycle

16-bit CPU registers and the power

of a RISC instruction set. The modern

design of the CPU offers versatility

through simplicity using only 27

easy-to-understand instructions and

seven consistent-addressing modes.

This results in a 16-bit CPU that is

more processing effective, consumes

little power, is smaller and more code

efficient. New ultra-low-power

high-performance applications are

now possible—developed rapidly

at a fraction of the code size.

MSP430 von-Neumann architecture — all program, data memory and peripherals share a

common bus structure. Consistent CPU instructions and addressing modes are used.

The MSP430 CPU core with sixteen 16-bit registers, 27 single-cycle

instructions and seven addressing modes results in higher processing

efficiency and code density.

Flexible Clock System

•Low frequency auxiliary clock

—Ultra-low-power stand-by mode

•High-speed master clock

—High-performance processing

•Stability over time and temperature

The MSP430 clock system is

designed specifically for battery-

powered applications. Multiple

oscillators are utilized to support

event driven burst activity. A low

frequency Auxiliary Clock (ACLK)

is driven directly from a common

32-kHz watch crystal—with no

additional external components.

The ACLK can be used for a back-

ground real-time clock self wake-up

function. An integrated high-speed

Digitally Controlled Oscillator (DCO)

can source the master clock which

is used by the CPU and high-speed

peripherals. By design, the DCO

is active and stable in less than

6 µs. MSP430 based solutions

efficiently use 16-bit RISC high-

performance in very short burst

intervals. This results in very high-

performance and ultra-low power

consumption.

High-Performance Analog

•12-bit or 10-bit fast SAR ADC

•14-bit hi-res SAR ADC

•16-bit slope ADC

Several high-performance data

converter solutions are available

in the MSP430 family. Innovative

comparator-gated timers are

available on all devices for high-

resolution slope type conversions.

This is ideal for measuring resistive

sensors such as thermistors when

coupled with a capacitor. A fast

200-ksps+ 12-bit ADC with very

high-integration is available on the

MSP430F13x/14x/43x/44x and is

ideal for demanding applications

such as electricity meters and

digital motor control. MSP430x32x

derivatives offer a 14-bit ADC with

a programmable current source.

Ultra-fast 6µs DCO start-up allows MSP430 systems to remain in low-power modes for the

longest possible interval—extending battery life. The DCO is fully user programmable.
