DESCRIPTION

The PPD16666A is a row (common) driver which contains a RAM capable of full-dot LCD display. With 240 outputs, this driver can be combined with a column (segment) driver PPD16661A which contains a RAM to display VGA (640 by 480 dots), 1/2 VGA, or 1/4 VGA, etc. By combining it with the PPD16661A, the PPD16666A can provide four gray levels by frame rate control.

With its built-in display RAM in the column driver, the driver kit can reduce current consumption, thus making it most suitable for the display section of a PDA or portable terminal.
