1.1 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.
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.

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.
The OTP (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 to manage 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 capabilities, demanded from
microcontroller applications, are fulfilled by
ST52x301 with 4 Analog Inputs, an asynchronous
Peripheral interface (UART) and an 8-bit I/O
communicationport in orderto 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) Conve r te r with a 4 analog
2/99
channel fast multiplexer (32µs c o n ve rs io n
time/channel).
It is possible to perform operations on data stored
in the Register File (16 bytes), allowing to manage
new inputs and feedback outputs.
The TRIAC/PWM Driver peripheral allows to
manage directly power devices, implementing
three different operating modes: Burst Mode
(i.e.Thermal Applications), Phase Angle
Partialization (i.e. Motors Control by TRIACs) and
high frequency PWM controls.
A programmable Timer with Internal Prescaler,
using both internal or external clock, is available.
The microcontroller configuration is stored in the
internal EPROM.
A powerful development environment,
FUZZYSTUDIO3.0, consisting of a board
and software t ools, allows an easy
configuration and use of ST52x301.
ST 52x301 is fully supported by
FUZZYSTUDIO3.0 so f t wa re t o ols a llowin g
to gra ph ic ally d es ig n a project and obtain an
optimized microcode.
ST52x301 exploits a SGS-THOMSON patented
strategy to store the MFs in its internal memory.
