ST52T301 General Description

ST52E301 ⁽¹⁾ and ST52T301⁽¹⁾ devices are members of theW.A.R.P.family of 8-bit DuaLogic] microcontrollers. They are able to perform, in an efficientway, both booleanand fuzzy algorithms, in order to reach the best performances that the two methodologies allow.

TheST52E301is theerasableEPROMversion and the ST52T301 is the OTP version.

The ST52x301 is completely developed and produced by STMicroelectronics using the reliable high performance CMOSM5E (O.7mm) process.

Thanks to Fuzzy Logic, ST52x301 allows to describea problemusing a linguistic modelinstead ofa 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 involvedrules.

The flexible I/O configuration of ST52x301 allows to interface with a wide range of external devices, like D/A converters, power control devices (SCRs, TRIACs) and external sensors.

TheOTP (One Time Programmable) device is fully compatible with the EPROM windowed version, which may be used to create prototype systems and for the pre-production phases.

The Fuzzy Core includes the fuzzifier (ALPHA calculator), the inference unit and the defuzzifier.

It allows tomanage up to 300 Rules (4 Inputs and 1 Output).The rules could be shared in different fuzzy subroutines that can be activated by user defined conditions.

The I /O capabil it ies, demanded f rom microcontroller applications, are fulfilled by ST52x301 with 4 Analog Inputs, an asynchronous Peripheral interface (UART) and an 8-bit I/O communicationport inorderto transferdata from/to the on-chip Register File.

The voltage reference provides biasing to the analog portion of the internal circuitry. The internal reference is a 2.5V Bandgap reference.

The voltage reference can supply up to 0.1 mA of current to power external circuitry.

ST52x301 includes an 8-bit sampling Analog to Digital (A/D) Conver ter with a 4 analog channel fast multiplexer (32s conversion time/channel).

It is possible to perform operations on data stored in the Register File (16 bytes), allowing to manage new inputs and feedbackoutputs.

The TRIAC/PWM Driver peripheral allows to manage directly power devices, implementing three different operating modes: Burst Mode (i.e.Thermal Applicat ions), Phase Angle Partialization (i.e. Motors Control by TRIACs) and high frequencyPWMcontrols.

A programmable Timer with Internal Prescaler, using both internal or external clock, is available.

The microcontroller configuration is stored in the internal EPROM.
