HD61830B General Description


The HD61830/HD61830B is a dot matrix liquid crystal graphic display controller LSI that stores the display data sent from an 8-bit microcontroller in the external RAM to generate dot matrix liquid crystal driving signals.

It has a graphic mode in which 1-bit data in the external RAM corresponds to the on/off state of 1 dot on liquid crystal display and a character mode in which characters are displayed by storing character codes in the external RAM and developing them into the dot patterns with the internal character generator ROM. Both modes can be provided for various applications.

The HD61830/HD61830B is produced by the CMOS process. Thus, combined with a CMOS microcontroller it can complete a liquid crystal display device with lower power dissipation.
