Features
n Video port accepts 18-bit video (NTSC R’G’B’) or 8/16-bit video (BT.601 Y’CbCr 4:2:2) at up to 150 QCIF fps (4 Mpix/s). n CPU port accepts packed graphics data (1.1.1, 3.3.2, (80x/68x) interfaces n Internal frame buffer supports up to 176RGB x 240 (18-bit pixels). n Flexible mounting/scan options provide for symmetric display layout n Programmable for smaller display resolutions such as 176RGB x 220, 144RGB x 176, 132RGB x 176, etc. n No external components. n Quiescent power ~2.5mW in 18-bit mode n Programmable color-depth allows selection of 3, 9, 12, or 18-bit color modes to further reduce power. n Power-saving automatic backlight intensity reduction based on statistics of image data or by direct system control. n Two-region partial display option for ultra-low power in handset stand-by mode. n Frame, line, or n-line inversion modes. n Programmable gamma curve control allows easy adjustment for optimum gray level placement and minimum flicker. n Programmable line rate supports up to 125Hz display refresh rate. n Separate addressing of two memory regions allows simultaneous loading of both streaming video and graphic/icon data n Versatile auto-increment addressing modes allow horizontal or vertical raster scanning. n Factory-calibrated internal clock provides accurate refresh control with no external components.
