• Description: Renesas 32-Bit RISC Microcomputer SuperHTM RISC engine Family / SH7700 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

A unified memory architecture is adopted for the LCD controller (LCDC) so that the image data
for display is stored in system memory. The LCDC module reads data from system memory, uses
the palette memory to determine the colors, then puts the display on the LCD panel. It is possible
to connect the LCDC to the LCD module* other than microcomputer bus interface types and
NTSC/PAL types and those that apply the LVDS interface.
Note: * LCD module can be connected to the LVDS interface by using the LSI with LVDS
26.1
The LCDC has the following features.
• Panel interface
• Supports 4/8/15/16-bpp (bits per pixel) color modes
• Supports 1/2/4/6-bpp grayscale modes
• Supports LCD-panel sizes from 16 × 1 to 1024 × 1024*
• 24-bit color palette memory (16 of the 24 bits are valid; R:5/G:6/B:5)
• STN/DSTN panels are prone to flicker and shadowing. The controller applies 65536-color
• Dedicated display memory is unnecessary using part of the synchronous DRAM (area 3) as the
• The display is stable because of the large 2.4-kbyte line buffer
• Supports the inversion of the output signal to suit the LCD panel's signal polarity
• Supports the selection of data formats (the endian setting for bytes, packed pixel method) by
• An interrupt can be generated at the user specified position (controlling the timing of VRAM
