Description

The MAXQ3212 microcontroller is a low-power, 16-bit RISC device that incorporates an analog comparator and a high-current I/O pin for directly driving an LED. The device is uniquely suited for cost-conscious applications such as battery-powered devices, system monitors, and white goods, but can be used in any application that requires high performance and low-power operation. The high-performance 16-bit RISC MAXQ® core and 8-bit accumulators are complemented by standard amenities such as timers and digital I/O. The power consumption per MIPS ratio is among the best in the 16-bit microcontroller industry.
