IZ7012 8-BIT CONTROLLER WITH FLASH MEMORY OF PROGRAMS The microcircuit IZ7012 – 8-bit controller with the FLASH – memory of programs (ROM testing coding with the watch functions, stopwatch with the possibility of the intermediate values fixation and writing of thirty results into memory). The microcircuit is intended for receipt, processing and indication of data on the liquid crystal indicator The microcircuit is applicable in the electronic household appliance devices (counters, electronic watches, electronic thermometers, pedometers). Main characteristics: • ROM capacity, QROM, bit………………………………3072х16; • PROM capacity, QROM1, bit……………………………1024х16; • RAM capacity, QRAM, byte…………………..………....128; • Number of bits of ALU, bits……………………………8; • Sources of interruptions…………………………….….from 8 inputs, From event counter at input IN8, from three timers; • Maximum number of controlled……………..……….136 (34 LCD control drivers LCD segments…………………………………….......at multiplex levels 1/2,1/3,1/4); • RISC-system of commands…………………………30 types of commands; • Stack……………………………………………………7 levels; • Permissible value of potential of static electricity, V………………..…………..…....1500 (for pins IN1-IN8, OSCI, OSCO)……………..…..….(1000) • Operating temperature range …………………..…- 40 … +85 °С. Ver.01/16.04.2009 1 IZ7012 Software of programs design for microcircuit Microcircuit IZ7012 contains in its composition EEPROM and mask ROM. ROM coding contains the control program, supporting programming the microcircuit EEPROM with application of software on the platform WINDOWS. The integrated programming environment for the controller IZ70ХХ permit to write and debug the applications for development and fabrication of the company devices. The software of IZ70ХХ includes the text editor, emulator, compilator, debugger. Software of IZ70ХХ supports also operation with LCD editor, utility of ROM “encoding”, utility of the EEPROM programming. LCD editor – editor for creation of files, containing description of LCD segments. These files are required for visualization of information, applied to LCD in process of debugging, and are used by the controller operation emulator. The program LCDDoc is intended for formation of the images, showing the controller operation modes, and their indication on LCD. The input information for the utility is the LCD description file, created by the LCD editor. The utility LCDset is intended for the LCD automatic routing and creation of the files, containing the compliance description between the LCD segments and the microcontroller pins. The ROM “encoding” utility RomTop is intended for formation of the layout layer from the executed program file. For EEPROM programming it is required to connect the computer parallel port with the installed software of IZ70ХХ by means of the four wire bunch to the microcircuit IZ7012 on the device PCB. Table 1 – Connection of microcircuit IZ7012 to the parallel port of the computer. Parallel Computer Port Pin Number Port Signal Microcircuit Contact Pad Number Identification Purpose 18, 19 Ground 06 GND Common pin (negative supply terminal) 02-07 Data0-Data5 21 UCC Power supply terminal (positive supply terminal) 08, 15 Data6, 11 IN1 Control input / output nError/nFault 09, 10 Data7, nAck 12 IN2 Control input / output Integrated environment of the programs design for the microcontroller IZ70ХХ is oriented for operation within the framework of the standard set of the technical and software means of the operating system WINDOWS on the personal computer. The minimum requirements to the technical means are determined by the installation requirements of the system WINDOWS 9Х, WINDOWS 2000/ХР. The graphics application within the framework of the given software requires the minimum display resolution of 640 × 480 dots and the color palette of not less than 256 colors. Software of IZ70ХХ can be submitted to the interested consumers.
