Simple functions like driving LEDs, monitoring system voltage levels, and waking up the main processor on an event detection are common functions on PCBs. Many of these functions are not mission-critical, so are typically implemented with fixed-function ICs. However, all of these simple functions can be implemented by a single chip. No matter what your design calls for, you can mix and match various functions on an MSP430 instead of using multiple discrete components, which will accelerate development efforts, enable cost savings, and save board space.
