FEATURES
2.1
Integrated Display Buffer
Embedded 80K byte SRAM display buffer.
2.2
Microcontroller Interface
Directly interfaces to :
Generic #1 bus interface with WAIT# signal
Generic #2 bus interface with WAIT# signal
Motorola MC68K
Motorola MC68EZ328/MC68VZ328 DragonBall
Hitachi SH-3
Hitachi SH-4
8-bit processor support with “glue logic”.
“Fixed” and low-latency CPU access times.
Registers are memory-mapped with dedicated M/R# input to select between memory and
register address space.
The contiguous 80K byte display buffer is directly accessible through the 17-bit address bus.
2.3
LCD Panel Support
4/8-bit monochrome STN interface.
4/8-bit color STN interface.
9/12/18-bit Active Matrix TFT interface.
Direct support for 18-bit Sharp HR-TFT interface (160x160, 320x240).
2.4
Display Modes
1/2/4/8/16 bit-per-pixel (bpp) color depths.
Up to 64 gray shades using Frame Rate Control (FRC) and dithering on monochrome passive
LCD panels.
Up to 256k colors on passive STN panels.
Up to 256k colors on active matrix LCD panels.
Resolution examples :
320x240 at a color depth of 8 bpp
160x160 at a color depth of 16 bpp
160x240 at a color depth of 16 bpp
2.5
Display Features
Display Rotate Mode : 90°, 180°, 270° counter-clockwise hardware rotation of display image.
Virtual display support : displays image larger than the panel size through the use of panning
and scrolling.
Floating Window Mode : displays a variable size window overlaid on background image.
2 Hardware Cursors (for 4/8/16 bpp) : simultaneously displays two cursors overlaid on
background image.
Double Buffering/Multi-pages: provides smooth animation and instantaneous screen updates.
