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 microputer 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.
