IZ7012
Software of programs design for microcircuit
Microcircuit IZ7012 contains in its composition EEPROM and mask ROM. ROM coding con-
tains 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 opera-
tion 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, contain-
ing 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 exe-
cuted program file.
For EEPROM programming it is required to connect the computer parallel port with the in-
stalled software of IZ70ХХ by means of the four wire bunch to the microcircuit IZ7012 on the de-
vice PCB.

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 op-
erating 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 mini-
mum 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.
