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. Although these I/O structures do contribute greatly to the overall power of a typical microcontroller, they alone are sometimes not enough. Historically, microcontrollers have been employed in the areas of ignition and fuel injection. They are now being applied to a wider range of areas, such as automatic transmissions, anti-skid braking, passenger environment and comfort control, maintenance, diagnostics, and instrumentation. Because of this, standard 8-bit-type architectures are becoming hard pressed to cope. There are two practical approaches to this problem. The first is to simply add more processors to the system, communicating the data of their individual functions through some sort of network. The second is to take advantage of a 16-bit data path CPU for increased throughput. Intel's MCS-96 (8096) family of microcontrollers addresses both these strategies. The 8096 is a high-performance, full 16-bit CPU which features a comprehensive control-oriented instruction set and powerful on-chip I/O. This includes a serial port which may be used as a high-speed interprocessor communications link.
