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.
