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 device to wake up from low-power modes to active mode in 3 µs (typical).
The MSP430FG6626 and MSP430FG6625 are microcontrollers with a high-performance 16-bit
analog-to-digital converter (ADC), dual 12-bit digital-to-analog converters (DACs), dual
operational amplifiers, a comparator, two universal serial communication interfaces (USCIs), USB
2.0, a hardware multiplier, DMA, four 16-bit timers, a real-time clock (RTC) module with alarm
capabilities, an LCD driver, and up to 73 I/O pins.
