ST52T301 Datasheet | STMicroelectronics

DESCRIPTION ST52E301 (1) and ST52T301 (1) devices are members of the W.A.R.P .family of 8-bit Dua Logic™ 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. The ST52E301is the erasable EPROMversion and the ST52T301 is the OTP version. The ST52x301 is pletely developed and produced by STMicroelectronics using the reliable high performance CMOSM5E (O.7µm) process. 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 plex system with very high accuracy. The linguistic approach is based on a set of IF-THEN rules, describing the control behaviour, and on Membership Functions associated to input and output variables. Fuzzy Inference is a set of operations which putes the output values according with the truth values of the involved rules. 1/99 ST52T301/E301 Figure 1.
