    R61505V Preliminary Specification Description The R61505V is a single-chip liquid crystal controller driver LSI for a-Si TFT panel, comprising RAM for a maximum 240 RGB x 320 dot graphics display, source driver, gate driver and power supply circuit. For efficient data transfer, the R61505V supports high-speed interface via 8-/9-/16-/18-bit ports as system interface to the host processor. The R61505V supports also RGB interface (VSYNC, HSYNC, DOTCLK, ENABLE and DB17-0) to display moving images. The power supply circuit incorporates step-up circuits and voltage follower circuits to voltage levels to drive TFT liquid crystal panel. The R61505V’s power management functions i.e. 8-color display, the deep standby mode and so on make this LSI an ideal driver for the medium or small sized portable devices with color display systems such as digital cellular phones or small PDAs, where long battery life is a major concern.
