MSP430 16-bit Ultra-Low Power MCUs

The MSP430™ MCU is the world's leading ultra-low-power microcontroller with a 16-bit RISC CPU architecture optimized for C and assembler programming with ultra-low-power architectures. The ultralow-power capabilities are available in active, standby and sleep modes.

The MSP430 family of microcontrollers offers a wide portfolio of highly integrated MCUs that are ideal for stepper and motor control applications. Customers have the option to select from low- or high-pin count MCUs along with different communication and analog peripherals.

MSP430 MCUs offer many different communication peripherals such as USB 2.0, SPI, I2C, IrDA and UART/LIN. Combined with timers that offer capture/compare/PWM outputs and a wide choice of analog peripherals such as comparators, 10-/12-bit ADC (up to 200 Ksps), 12-bit DAC and 16-bit sigma-delta modules, these MCUs can be used to control stepper and DC motors in printers, fans, antennas, toys and many other applications.

TI provides robust design support for the MSP430 microcontroller including technical documents, training, tools and software.

MSP430F51x2 Devices Feature New High-Resolution Timer_D for Finer Motor Precision

Timer_D is a 16-bit timer/counter with multiply capture/compare registers supporting up to 256-MHz / 4-ns resolution suitable for precision motor control.

Timer_D can support multiple capture/compares, PWM outputs and interval timing. Timer_D also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.

MSP430G2xx Value Line Series = Low Cost AND Low Power

TI's new Value Line of MSP430™ MCUs allows customers to take advantage of this family's ultra-low power (ULP) and 16-bit performance for cost-sensitive applications, which traditionally have depended on 8-bit microcontrollers.

ULP Features:

• 300-μA active current (1 MHz, 3 V)
• 0.5-μA standby current (LPM3)
• 0.1-μA power-down current (LPM4)
• 1-μs wake-up time and integrated brown-out reset (BOR)
• Watchdog timer (WDT)

Integrated Peripherals

Comparators, 10-bit ADC, SPI, I2C and UART communication. Some Value Line devices also feature integrated capacitive sense I/Os to enable low-cost touch-pad implementations (reduced PCB BOM).
