Ti MSP series ultra-low power microcontrollers have a wide variety, and each member device is equipped with different peripheral sets to meet the needs of various applications. This architecture, combined with five low-power modes, is the best choice to prolong the battery life of portable measurement applications. The device has a powerful 16 bit precision

RISC CPU uses 16 bit registers and constant generator to obtain the highest coding efficiency. The digital controlled oscillator (DCO) allows the device to wake up from low-power mode to active mode in less than 5 µ s.

The msp430f51x2 microcontroller consists of 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 three channel DMA, 5V Tolerant I / O, and up to 29

I / O pins.
