Specialized I/O and High-Speed CPU Yields Efficient Microcontroller for Automotive Applications

Due to increasing governmental demands for tighter exhaust emission standards, a greater fuel economy, and the contrasting consumer desire for higher performance and efficiency from smaller displacement power plants, the automotive industry is turning to electronics for a wider range of applications. Electronics, specifically in the form of the microcontroller, has evolved specialized on-chip peripheral functions to meet this need. Higher resolution analog-to-digital converters, high-speed inputs and outputs, timer/counters, and watchdog timers have been added on-board to augment standard digital I/O ports, make a more cost-effective solution, and to unburden the CPU.
