Msp430f5437aipn 16 bit ultra low power microcontroller 32-bit HW multiplier
explain
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 works with a variety of low-power modes and is optimized to extend battery life in portable measurement applications. The device has a powerful 16 bit RISC CPU
16 bit register and constant generator help to achieve higher coding efficiency. This digital controlled oscillator (DCO) enables the device to wake up from low-power mode to active mode within 3.5 µ s (typical).
Msp430f543xa and msp430f541xa series microcontroller configurations include three 16 bit timers, a high-performance 12 bit ADC, up to four USCIS, a hardware multiplier, DMA, RTC module with alarm function and up to 87 I / O pins.
