These outputs are useful for producing signals of varying duty cycle, for example, to provide control of variable motor speeds. Analog to Digital Converter Options While digital signals are useful for high speed processing of data and executing decision trees, many microcontrollers must interact with realworld events. This means they must be able to communicate with analog signals. There are also special functions such as microcontrollers designed for television applications. This makes it very convenient for compact, low-cost video applications.
Many applications have stringent space requirements.
Philips is leading the way with small footprint options. This small footprint packaging, especially the availability of quad flat packs, is an important competitive advantage for Philips. Most of its competitors do not offer their products in these space saving QFP packages that have become a fast growing trend. This device is very attractive to a large number of high volume consumer OEMs and industrial OEMs where board space is at an absolute premium. Low Voltage, Low Power Operation Versions Possibly the most important variation in the 80C51 family is the array of low power, low voltage operation versions introduced in the last year.
