R61503U
SPECIFICATION
Description
The R61503U is a one-chip controller driver LSI for 262,144-color TFT panel, incorporating RAM for a
maximum 176RGB x 220-dot graphics display and 528-channel source driver. The R61503U provides a
one-chip solution to drive TFT panel by generating gate drive signal and liquid crystal drive power supply.
To transfer data efficiently, the R61503U supports high-speed interface via 8-/9-/16-/18-bit port as system
interface to microcomputer and high-speed RAM write function. As moving picture interface, the
R61503U supports RGB interface (VSYNC, HSYNC, DOTCLK, ENABLE, DB17-0) via 18-/16-/6-bit port
and VSYNC interface (system interface + VSYNC). The moving picture interface enables moving picture
display at the arbitrary position determined by window address setting. The window address setting
enables displaying a moving picture and the data written in the internal RAM simultaneously and allows
transferring moving picture data not constrained by the position of still picture display. By writing moving
picture data via moving picture interface in the window address area, the number of data transfer can be
minimized and the power consumption by the system can be reduced.
The R61503U can operate at low voltage up to 1.65V for the power supply to the I/O interface unit and it
incorporates a voltage follower circuit to generate liquid crystal drive voltage. The R61503U’s power
management functions such as 8-color display and deep standby and so on make this LSI an ideal driver for
the medium or small sized portable products such as digital cellular phones and small PDAs, where long
battery life is a major concern.
