DESCRIPTION
IZ6450A, IZ6451A
DOT MATRIX LCD DRIVER
IZ6450/IZ6451 are dot matrix LCD (Liquid Crystal Display) drivers, designed for the dis-
play of characters and graphics.
The drivers generate LCD drive signals derived from bit mapped data stored in an internal
RAM.
Design of ICs driver provides very low power dissipation at a wide range of operating volt-
ages.
These features give the designer a flexible means of implementing small to medium size
LCD displays for compact, low power systems.
IZ6450A drive 16 lines of 61 characters each.
IZ6451A operates only 80 columns LCD and works under control of IZ6450A.
Two IZ6450A can be used for control of LCD with rows number more than16 (but not
more than 32). Thus one IC operates as "Master" and the second as "Slave".
One IZ6450A operates as “Master”, and one or few IZ6450A or IZ6451A is used in “Slave”
mode for control of LCD with number of columns more than 61
IZ6450A operates on frequency 18kHz as from the built in RC-generator (external
resistor), and from external clocking.
IZ6451A operates on frequency 18kHz from external clocking.
The most similar on parameters functional equivalents are NJU6450A, NJU6451A
(New Japan Radio Co).
Microcircuits support the data exchange protocol with MPU family 80XXX (Intel),
and MPU family 68XXX (Motorola) to receive the information to display on LCD from
MPU.
Microcircuits are used in calculators, pagers, notebooks, translators and other
products, demanding simultaneous displaying of graphic and any fonts text information on
LCD.
