The HD64645/HD64646 LCTC is a control LSI for large size dot matrix liquid crystal displays.

The LCTC is software compatible with the HD6845 CRTC, since its programming method of internal registers and memory addresses is based on the CRTC.

A display system can be easily converted from a CRT to an LCD.

such as vertical and horizontal scrolling, and various types of character attribute functions such as reverse video, blinking, nondisplay (white or black), and an OR function for simple superimposition of character and graphic displays. The LCTC also provides DRAM refresh address output. A compact LCD system with a large screen can be configured by connecting the LCTC with the HD66110ST (column driver) and the HD66113T (common driver) by utilizing 4-bit × 2 data outputs. Power dissipation has be.
