2.Scope of applicationAnalog and digital sensor systems and data loggers.
3.DescriptionTI's MSP430 family of ultra-low-power microcontrollers includes several devices with peripheral sets that can be used in a wide range of applications. This architecture, combined with a variety of low-power modes, is the best choice for extending battery life in portable measurement applications. The microcontroller features a powerful 16-bit reduced instruction set (RISC) CPU that uses 16-bit registers as well as a constant generator for maximum coding efficiency. This numerically controlled oscillator (DCO) allows the device to operate at 3Wake up from low-power mode to active mode within 5 s (typical).
