1 GENERAL DESCRIPTION
1.1 Introduction
ST52T410/ST52x420 are 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.
ST52T410/ST52x420 are produced by
STMicroelectronics using the reliable high
performance CMOS 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.
ST52T410/ST52x420 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 remainder) are available to
implement complex functions by using a single
instruction. The program memory utilization and
computational speed is optimized.
Fuzzy Logic dedicated structures in ST52T410/
ST52x420 ICU
’
s can be exploited to model
complex systems with high accuracy in a useful
and easy way.
Fuzzy Expert Systems for overall system
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.
The Timer/PWM peripheral allows the
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.
ST52x420 includes an 8-bit Analog to Digital
Converter with an 8-analog channel Multiplexer.
Single/Multiple channels and Single/Sequence
conversion modes are supported.
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 board and software tools allows an easy
configuration and use of ST52T410/ST52x420.
The VISUAL FIVE
TM
software tool allows
development of projects through a user-friendly
graphical interface and optimization of generated
code.
1.2 Functional Description
ST52T410/ST52x420 ICUs can work in two
modes:
I
Memory Programming Mode
I
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 ST52T410/ST52x420 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:
