Description
Microcircuit IZ7066 performs the functions of controller and matrix liquid crystal
display driver, displaying the signs and symbols. All functions, which are necessary for
control of the matrix LCD, are realized on the single chip.
Functional Description
Controller of the liquid crystal display IZ7066 can function under control of both the
four digit and eight digit micro-processor. Table 1 lists description of the IZ7066
microcircuit pins, used for connection to the microprocessor.
Microprocessor can control only the command register and data register of the liquid
crystal display of the microcircuit IZ7066. Command register stores the command codes,
such as «Clear Display» and «Shift Cursor or Display» and information about the
addresses of DD RAM and symbol generator RAM (CG RAM). The data from the
microprocessor can be written only into this register. The data register serves for the
temporary data storage or storage of those data, written or read into/from display data
RAM and the symbol generator RAM.
The data, written into the data register from the microprocessor, by means of the
internal operation, are automatically rewritten into DD RAM or CG RAM. The data register
is used also for the data storage, when they are read out from DD RAM or CG RAM.
