MAXQ3108 Low-Power, Dual-Core Microcontroller 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. Each core has access to an independent math accelerator a multiply/accumulate unit . The UserCore supports SPI , I2C, two UART channels with one channel supporting IR carrier modulation, a trimmable real-time clock RTC , battery-backed RTC registers, and data memory. The DSPCore is fully user programmable and configurable. With the standard 32,768Hz crystal, the DSPCore operates at 10.027MHz, while the UserCore runs at 5.014MHz.
