The Texas Instruments MSP430 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 less than 5 µs.
●The MSP430F5310, MSP430F5309, and MSP430F5308 devices are microcontroller configurations with a 3.3-V LDO, four 16-bit timers, a high-performance 10-bit analog-to-digital converter (ADC), two universal serial communication interfaces (USCIs), a hardware multiplier, DMA, a real-time clock (RTC) module with alarm capabilities, and 31 or 47 I/O pins.
●The MSP430F5304 device is a configuration with a 3.3-V LDO, four 16-bit timers, a high-performance 10-bit ADC, two USCIs, a hardware multiplier, DMA, an RTC module with alarm capabilities, and 31 I/O pins.
