General Description
The MAXQ3108 is a low-power microcontroller that features two high-performance MAXQ20 cores: a dedicated core (DSPCore) for intensive data processing and a user core (UserCore) for supervisory functions. The two cores can operate at different clock speeds, allowing lower system power consumption for even processing intensive applications. The UserCore can be configured to run at the lowest clock rate possible for monitoring the peripherals for communication activities, while the DSPCore runs at the highest speed.
