1. General Description
HX8302A is a 396-channel source driver LSI with internal RAM for maximum 132RGB-by-176-dot
graphics on TFT displays in 65536 colors. It is for driving TFT color LCD displays in combination with
the gate driver/power IC (HX8609A). With internal bit-operation functions, 16-bit high-speed bus
interface, and high-speed RAM-write functions enable efficient data transfer and high-speed rewriting of
data to the graphics RAM.
HX8302A has various functions for reducing the power consumption of an LCD system and has a
low-voltage operation (1.8V min.) with an internal RAM to display a maximum of 132RGB-by-176-dot
color. Since HX8302A incorporates a circuit that interfaces with the HX8609A, it can set instructions to
HX8609A. In addition, moderate power control can be achieved by combining these hardware functions
with software functions, such as a partial display, 8-color display mode, sleep and standby modes. This
LSI is suitable for any medium-sized or small portable battery-driven product requiring long-term driving
capabilities, such as digital cellular phones, bi-directional pagers, and small PDAs.
2. Features
