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.
