ST52T430/E430
GENERAL DESCRIPTION
ST52x430 is a member of the ST52xxx family of
8-bit DuaLogic microcontrollers. It is able to
perform, in an efficient way, both boolean and
fuzzy algorithms, in order to reach the best
performances that the two methodologies allow.
Hardware multiplier and divider are available to
implement complex functions by using a single
instruction thus optimizing the program memory
utilization and the computational speed.
It is produced by STMicroelectronics using the
reliable high performance CMOSM6XE (O.5mm)
process.
Thanks to Fuzzy Logic, ST52x430 allows to
describe a problem using a linguistic model
instead of a mathematical model. In this way it is
very useful and easy to modelize and control
complex systems with very high accuracy. It is
possible to implement fuzzy expert systems for the
overall system management and real time
controller at a very competitive cost.
The linguistic approach is based on a set of
IF-THEN rules, describing the control behavior,
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 ST52x430 allows
to interface with a wide range of external devices,
like D/A converters or power control devices.
ST52x430 pins are configurable (Alternate
Function), allowing to set the input, or output,
signals on each single pin, as shown in figures 1.2
and 1.3.
The OTP (One Time Programmable) device is fully
compatible with the EPROM windowed version,
which may be used for the prototyping and
pre-production phases of development.
The EPROM can be locked by user to prevent
external undesired operations.
It is possible to store up to 341 Membership
Functions, with triangular and trapezoidal shapes,
or singleton values if fuzzy algorithms have to be
implemented.
Three TIMER/PWM drivers allow to manage power
devices and timing signals, implementing different
operating modes and high frequency PWM (Pulse
With Modulation) controls.
One of these programmable timers, with Internal
Prescaler, can utilize internal or external
