描述 Description

The MM912_P812 is an engine control IC, combining an MCU (S12P) and analog control die (MC33812) intended for motorcycle and other single/dual cylinder small engine control applications.
The IC reduces design complexity, bill of materials and manufacturing cost while helping to shorten the customer’s time to market.
Other benefits for your small engine designs include:
Increased fuel efficiency when converting from a mechanical system to an electrical system
Improved emissions using electrical system of this IC compared to a mechanical system
Easiest way to interface a MCU to DC loads
Simplified system design
Reduced board space
Reduced number of components
Enhanced reliability
