- Maximum Resolution: 4096 x 4096 pixels (1 bit/pixel mode) CRT display control - Split Screens: three displays and one window Zoom: 1 to 16 times Scroll: vertical and horizontal Interleaved access mode for flashless display and superimposition External synchronization between ARTCs or between ACRTC and external device (TV system or other controller.
DMA interface Two programmable cursors Three Scan modes - Non-interlaced - Interlace sync - Interlace sync and video Interrupt request to MPU 256 characters/line 32 raster/ line, 4096 rasters/screen Maximum clock frequency: 20MHz CMOS, single +5V power supply The IA63484 is a "plug-and-play" drop-in replacement for the original Hitachi© HD63484.
This replacement IC has been developed using innovASIC’s MILESTM, or Managed IC Lifetime Extension System, cloning technology.
This technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC.
MILESTM captures the design of a clone so it can be produced even as silicon technology advances.
MILESTM also verifies the clone against the original IC so that even the "undocumented features" are duplicated.
This data sheet documents all necessary engineering information about the IA63484 including functional and I/O descriptions, electrical...
