Freescale's two-chip platform for electronic control solution

Freescale has released a high-integrated analog device with a 16-bit microcontroller (MCU), ideal for small engine control.

This small engine control platform consists of the MCZ33812, an analog integrated circuit (IC) to control fuel and spark in EFI and electronic carburetion (e-carb) systems, and a S12 MCU. EFI-equipped small engines also increase horsepower and improve gas mileage.

The MCZ33812 analog IC packs a voltage regulator, fuel injector driver and ignition pre-driver, a relay and lamp driver, watchdog timer and reset generator for small engine control. This integration, enabled by SMARTMOS technology.

Key features are,

1 fuel injector low-side driver (current limit - 4.0 A typical)
1 relay, fuel pump or second injector low-side driver (current limit - 4.0 A typical)
1 lamp low-side driver (current limit - 1.5 A typical)
1 ignition pre-driver with independent high- and low-side outputs

"State-of-the-art electronic control helps small engines produce more horsepower and less pollution than their carbureted predecessors," said Steve Nelson, global manager of automotive marketing at Freescale Semiconductor. "Emissions regulations are influencing small engine design, and the evolution from mechanical to electronic control is transforming the small-displacement motorcycle and scooter market. Freescale has long been a pioneer in advanced engine technology for automobiles, and our new platform solution is an important step on the path to greener small engines."

The suggested applications for this platform includes small-displacement two- and four-stroke engines used in motorcycles, mopeds, scooters and three-wheeled taxis, and also ideal for small engine designs in outdoor power equipment, such as lawnmowers, garden tractors, trimmers, edgers, chainsaws, snow and leaf blowers, tillers, electrical generators and outboard motors.

The MCZ33812 reference design evaluates a two-chip solution based on the MCZ33812 and S12P MCU and emulates a complete small engine electronic control unit (ECU).
