ARTC HD63484

Hitachi LSI HD63484 Advanced CRT Controller chip (ACRTC) is a GPU created by Hitachi in 1984 that supports 4K display resolution.

Description

The LSI HD63484 was built in 2 ÃŽÂ¼m CMOS technology and had about 60,000 MOSFETs and could operate at 8 MHz. ACRTC introduced a screen resolution of 4096×4096 pixels at 1-bit color depth (monochrome), or 1024×1024 at 16-bit color (65,536 colors). Focused on computer graphics for the emerging desktop publishing market with bitmap printing. The chip had the ability to program the synchronization signal of CRT monitors. It could support up to 2 megabytes of video memory and offered an asynchronous DMA bus interface that could be mapped to 16-bit ISA and VME buses.
