com DATA SHEET MOS INTEGRATED CIRCUIT µPD7225 PROGRAMMABLE LCD CONTROLLER/DRIVER The µPD7225 is a software-programmable LCD (Liquid Crystal Display) controller/driver.
The µPD7225 can be serially interfaced with the CPU in a microcomputer and can directly drive 2, 3, or 4-time division LCD.
The µPD7225 contains a segment decoder which can generate specific segment patterns.
In addition, the µPD7225 can be used to control on/off (blinking) operation of a display.
