7 / 84 page ST52T410/T420/E420 7/84 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. S T 52 T 4 10/ ST 5 2 x420 a r e p r o duced b y STMicro electron ics using the relia ble 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. Fu zzy Exp e rt Syst em s f o r ove r all syst em 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 / PWM pe r i pher a l allow s 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. 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. Th e VI SU AL FIVE TM s o f t wa re to ol al lo ws 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: RESET TEST VPP Vss Vss 12V/VDD |
