Description

FULL DATA SHEET (PDF, 324kB) Download   E-Mail 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. Note: Designers must have the following documents to fully use all the features of this device. This data sheet contains pin descriptions, feature overviews, and electrical specifications. Errata sheets contain deviations from published specifications. The user's guides offer detailed information about device features and operation.
