The flexible I/O configurationof ST52x301 allows
to interface with a wide range of external devices,
like D/A converters, power controldevices (SCRs,
TRIACs) and external sensors.
TheOTP(OneTimeProgrammable)deviceis fully
compatible with the EPROM windowed version,
which may be used to create prototype systems
and for the pre-productionphases.
The Fuzzy Core includes the fuzzifier (ALPHA
calculator),the inferenceunit and the defuzzifier.
It allows tomanage upto 300Rules(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,
microcontroller applications, are fulfilled by
ST52x301with 4 Analog Inputs,an asynchronous
Peripheral interface (UART) and an 8-bit I/O
communicationportinorderto transferdatafrom/to
the on-chip Register File.
The voltage reference provides biasing to the
analog portion of the internalcircuitry. Theinternal
referenceis a 2.5V Bandgapreference.
The voltage reference can supply up to 0.1 mA of
current to power external circuitry.
ST52x301includes an 8-bit sampling Analog to
Digital (A/D) Converter with a 4 analog
demanded
from
channel fast multiplexer (32
μ
s conversion
time/channel).
It is possibleto perform operationson data stored
in the RegisterFile (16 bytes),allowing to manage
newinputs and feedbackoutputs.
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 frequencyPWMcontrols.
A programmable Timer with Internal Prescaler,
using both internal or externalclock, is available.
The microcontroller configuration is stored in the
internalEPROM.
