GENERAL DESCRIPTION
ST52E301 (1) and ST52T301 (1) devices are members of the W.A.R.P .family of 8-bit DuaLogic™ microcontrollers. They are able to perform, in an efficient way, both booleanand fuzzy algorithms, in order to reach the best performances that the two methodologies allow. TheST52E301is the erasableEPROMversion and the ST52T301 is the OTP version. Thanks to Fuzzy Logic, ST52x301 allows to describe a problemusing a linguistic model instead of a mathematicalmodel.In thisway it is very useful and easy to modelize complex system with very high accuracy. Fuzzy Inference is a set of operations which computes the output values according with the truth values of the involved rules. 1/99 ST52T301/E301 Figure 1.
