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. The ST52x301 is completely 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 complex 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 computes the output values according with the truth values of the involved rules. 1/99 ST52T301/E301 Figure 1.

The OTP (One Time Programmable) device is fully compatible with the EPROM windowed version.
