The MAXQ3108 is a low-power microcontroller that fea-

tures two high-performance MAXQ20 cores: a dedicat-

ed 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 multi-

ply/accumulate unit). The UserCore supports SPI™,

IR carrier modulation, a trimmable real-time clock

(RTC), battery-backed RTC registers, and data memo-

ry. The DSPCore is fully user programmable and con-

figurable. With the standard 32,768Hz crystal, the

DSPCore operates at 10.027MHz, while the UserCore

runs at 5.014MHz.
