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.","metaTitle":"HD6445CP4 CRT Character Display Controller, Active","metaDescription":"HD6445CP4 CRT character display controller from Hitachi.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/HD6445CP4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/HD6445CP4 when reusing this data.
