This manual describes the Himax’s HX8312-A 240RGB*320 dots resolution driving controller.
The HX8312-A is designed to provide a single-chip solution that combined a gate driver, a
source driver, power supply circuit, and internal graphics SRAM for 262,144 colors to drive a
TFT panel with 240RGB*320 dots at maximum.
The HX8312-A can be operated in low-voltage (1.65V) condition to the interface and
integrated internal boosters that produce the liquid crystal voltage, breeder resistance and
the voltage follower circuit for liquid crystal driver. In addition, the HX8312-A also supports
various functions to reduce the power consumption of a LCD system via software control,
such as an standby mode and 8-color display mode. The HX8312-A has five system
interfaces: an I80-system and M68-system 18-/16-/9-/8-bit bus interface, VSYNC
interface(internal clock, DB17-0) , serial data transfer interface and RGB18-/16-/6-bit bus
interface(DOTCLK, VSYNC, HSYNC, ENABLE). In RGB interface and VSYNC interface
mode, the combined use widow address function enables to display data in a moving picture
area and data in internal RAM at once, which makes it possible to transfer display data only
when rewriting a screen and minimize data transfers.
The HX8312-A is suitable for any small portable battery-driven product and requiring
long-term driving capabilities, such as small PDAs, digital cellular phones and bi-directional
pagers
