7 / 106 page ST52F510/F513/F514 7/106 1 GENERAL DESCRIPTION 1.1 Introduction ST52F510/F513/F514 are devices of ST FIVE family of 8-bit Intelligent Controller Units (ICU), which can perform, both boolean and Fuzzy algorithms in an efficient manner, in order to reach the best performances that the two methodologies allow. Produced by STMicroelectronics using the reliable high performance CMOS process for Single Voltage Flash versions, ST52F510/F513/F514 include integrated on-chip peripherals that allow maximization of system reliability, and decreased system costs in order to minimize the number of external components. The flexible I/O configuration of ST52F510/F513/ F514 allow one to interface with a wide range of external devices (for example D/A converters or power control devices), and to communicate with the most common serial standards. ST52F510/F513/F514 pins are configurable. The user can set input or output signals on each single pin in 8 different modes, reducing the need for external components in order to supply a suitable interface with the port pins. A hardware multiplier and divider, together with a wide instruction set, allow the implementation of complex functions by using a single instruction. Therefore, program memory utilization and computational speed is optimized. Fuzzy Logic dedicated structures in ST52F510/ F513/F514 ICU’s can be exploited to model complex system with high accuracy in a useful and simple manner. Fuzzy Expert Systems for overall system management and Fuzzy Real time Controls can be designed to increase performance at competitive costs. The linguistic approach characterizing Fuzzy Logic is based on a set of IF-THEN rules, which describe the control behavior and on Membership Functions associated with input and output variables. Up to 340 Membership Functions, with triangular and trapezoidal shapes, or singleton values are available to describe fuzzy variables. The Timer/PWM peripheral allows one to manage power devices and timing signals, by implementing different operating modes and high frequency PWM (Pulse Width Modulation) controls. Input Capture and Output Compare functions are available on the Timers. The Timer has a 16-bit programmable internal Prescaler and a 16-bit Counter, which can use internal or external START/STOP signals and clock. An internal programmable WATCHDOG is available to avoid loop errors and reset the ICU. ST52F510/F513/F514 includes a 10-bit, self- calibrating, Analog to Digital Converter with an 8- analog channel Multiplexer. Single/Multiple channels and Single/Sequence conversion modes are supported. External reference can be supplied to obtain more stability and precision in the conversion. ST52F510/F513/F514 supply different peripherals to implement the most common serial communication protocols. SCI allows the performance of serial asynchronous communication (UART). I2C and SPI peripherals allow the implementation of synchronous serial protocols. I2C peripherals can work both in master and slave mode. SPI implements Single and Multi Master modes using 3-wire. Up to 8 interrupt vectors are available, which allow synchronization with peripherals and external devices. Non-Maskable Interrupt and S/W TRAP are available. All interrupts have configurable priority levels and are maskable excluding the Non-Maskable Interrupt, which has fixed top level priority. Two versatile Port Interrupts are available for synchronization with external sources. The ST52F510/F513/F514 also include an on-chip Power-on-Reset (POR), which provides an internal chip reset during power up situation and a Programmable Low Voltage Detector (PLVD), which causes the ICU to reset if the voltage source VDD dips below a threshold. Three programmable thresholds are available, allowing to work with different supply voltages (from 2.7 to 5.5 V). In order to optimize energy consumption, two different power saving modes are available: Wait mode and Halt mode. Internal Oscillator at 10 MHz ± 1% is available. External clock, quartz oscillator or RC oscillator are also applicable. The device always starts with the Internal Oscillator, then it reads an Option Byte where the clock mode to be used is programmed. Program Memory addressing capability addresses up to 8 Kbytes of memory location to store both program instructions and data. Memory can be locked by the user in order to prevent external undesired operations. Operations may be performed on data stored in RAM, allowing direct combination of new inputs and feedback data. All RAM bytes are used like Register File. An additional RAM bench is added to the Program Memory addressing space in order to allow the management of the System/User Stacks and user data storage. |
