The TI MSP family of ultra-low-power microcontrollers consists of several devices
featuring different sets of peripherals targeted for various applications. The architecture,
combined with five low-power modes, is optimized to achieve extended battery life in portable
measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and
constant generators that contribute to maximum code efficiency. The digitally controlled oscillator
(DCO) allows the devices to wake up from low-power modes to active mode in less than 5 µs.
The MSP430F51x2 microcontrollers include two 16-bit high-resolution timers, two USCIs
(USCI_A0 and USCI_B0), a 32-bit hardware multiplier, a high-performance 10-bit ADC, an on-chip
comparator, a 3-channel DMA, 5-V tolerant I/Os, and up to 29 I/O pins.The MSP430F51x1 microcontrollers include two 16-bit high-resolution timers, two USCIs
(USCI_A0 and USCI_B0), a 32-bit hardware multiplier, an on-chip comparator, a 3-channel DMA, 5-V
tolerant I/Os, and up to 29 I/O pins.Typical applications for these devices include analog and digital sensor systems, LED
lighting, digital power supplies, motor controls, remote controls, thermostats, digital timers, and
hand-held meters.For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
