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.
