DESCRIPTION
IZ6450A, IZ6451A DOT MATRIX LCD DRIVER IZ6450/IZ6451 are dot matrix LCD (Liquid Crystal Display) drivers, designed for the display 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 voltages. 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 operates on frequency 18kHz from external clocking. 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.
