Product details

Package and mounting

The Hitachi HD6445CP4 is a CRT character display controller — it generates the timing and raster-scan signals needed to drive a monochrome or colour CRT monitor for character-based text output. Think of it as the brains behind a dumb terminal or an industrial panel that shows alphanumeric readouts on a CRT. It handles the horizontal and vertical sync generation, character row addressing, and cursor control, offloading that work from the main CPU.

For a part of this vintage (CRT display controllers are not a high-volume commodity anymore), active status is a solid signal that Hitachi (now Renesas) still supports the line.

Bulk packaging — the repair bench favourite

The package itself is a DIP footprint (the CP suffix in the order code), through-hole, which makes hand-replacement straightforward.

Frequently asked questions

What is the HD6445CP4 IC used for?

The HD6445CP4 is a CRT character display controller. It generates the horizontal and vertical sync signals, character row addressing, and cursor control for driving a CRT monitor in character-based text display applications — typical in old computer terminals, industrial panel readouts, and test equipment with CRT displays.

What is the HD6445CP4 alternative?

The TW8817-TA3-GRS is sometimes listed as a functional alternative, but it is a surface-mount video controller for composite video standards (NTSC/PAL/SECAM) with I²C/SPI interface. It is not a pin-compatible or direct replacement for the HD6445CP4's character-mode CRT timing controller. For a drop-in repair or new design expecting the HD6445CP4's specific interface, the original part is the correct choice.
