1 GENERAL DESCRIPTION
1.1 Introduction
ST52x430 is an 8-bit Intelligent Control Units (ICU)
of the ST Five Family, which can perform both
boolean and fuzzy algorithms in an efficient
manner, in order to reach the best performances
that the two methodologies allow.
ST52x430 is produced by STMicroelectronics
using the rel iab le hig h perform ance CM O S
process, including integrated-on-chip peripherals
that allow maximization of system reliability,
decreasing system costs and minimizing the
number of external components.
The flexible I/O configuration of ST52x400/440
allows for an interface with a wide range of external
devices, like D/A converters or power control
devices.
ST52x430 pins are configurable, allowing the user
to set the input or output signals on each single pin.
A hardware multiplier (8 bit by 8 bit with 16 bit
result) and a divider (16 bit over 8 bit with 8 bit
result and 8 bit rem ainder) are availabl e to
implement complex functions by using a single
instruction. The program memory utilization and
computational speed is optimized.
Fuzzy Logic dedicated structures in ST52x430
ICU’s can be exploited to model complex systems
with high accuracy in a useful and easy way.
F u zzy Exp e r t Syste m s fo r o v e r a l l syste m
management and fuzzy Real time Controls can be
designed to increase performances at highly
competitive costs.
The linguistic approach characterizing Fuzzy Logic
is based on a set of IF-THEN rules, which describe
the control behavior, as well as on Membership
Functions, which are associated to input and
output variables.
Up to 334 Membership Functions, with triangular
and trapezoidal shapes, or singleton values are
available to describe fuzzy variables.
T h e T i m e r / P W M pe ri ph era l al l o ws t h e
management of power devices and timing signals,
implementing different operating modes and high
frequency PWM (Pulse With Modulation) controls.
Input Capture and Output Compare functions are
available on the TIMER.
The programmable Timer has a 16 bit Internal
Prescaler and an 8 bit Counter. It can use internal
or external Start/Stop signals and clock.
An internal programmable Watchdog is available
to avoid loop errors and to reset the ICU.
ST52x430 includes an 8-bit Analog to Digital
Converter with an 8-analog channel Multiplexer.
Single/Multiple channels and Single/Sequence
conversion modes are supported.
A Serial Communication peripheral (SCI), which
uses the UART protocol allows data transfer from
the ST52x430 to other external devices.
In order to optimize energy consumption, two
different power saving modes are available: Wait
mode and Halt mode.
Program Memory (EPROM/OTP) addressing
capability addresses up to 8 Kbytes of memory
locations to store both program instructions and
permanent data.
EPROM can be locked by the user to prevent
external undesired operations.
Operations may be performed on data stored in
RAM, allowing the direct combination of new input
and feedback data. All bytes of RAM are used like
Register File.
OTP (One Time Programmable) version devices
are fully compatible with the EPROM windowed
version, which may be used for prototyping and
pre-production phases of development.
A powerful development environment consisting of
a b oard a nd software too ls al low s a n easy
configuration and use of ST52x430.
T h e VI SU AL F I VETM s o f twa re t ool al l o ws
development of projects through a user-friendly
graphical interface and optimization of generated
code.
1.2 Functional Description
ST52x430 ICU can work in two modes:
s
Memory Programming Mode
s
Working Mode
according to RESET and Vpp signals levels (see
pins description).
Note: When RESET=0 it is advisable not to use
the sequence “101010“ to port PA (7 : 2).
1.2.1 Memory Programming Mode.
The ST52x430 memory is loaded in the Memory
Programming Phase. All fuzzy and standard
instructions are written inside the memory.
This phase starts by setting the control signals as
illustrated below:
When this phase starts, the ST52x430 core is set
to RESET status; then 12V are applied to the Vpp
RESET
