DESCRIPTION
The ST8012 Low-power liquid crystal display power supply circuit equipped internally. Booster circuit (with Boost ratio of 2X/3X/4X/5X/6X) Abundant command functions LCD bias set, electronic volume, VSS voltage regulation internal resistor ratio and booster frequency. All Functions have initial value, user can use the default value or setting by programmable pin to set. If select segment mode then except booster circuit will opened others circuit (follower and regulator circuit) will automatic closed. When don’t used the serial interface, we can select one of default modes by serial interface pins please see Table5. Package: 154-pin COB. (Segment mode) Shift clock frequency - 20 MHz (MAX.): VDD = +5.0 ± 0.5 V - 15 MHz (MAX.): VDD = +3.0 to + 4.5 V - 12 MHz (MAX.): VDD = +2.5 to + 3.0 V Adopts a data bus system 4-bit parallel / serial input modes are selectable with a mode (P/S) pin Automatic transfer function of an enable signal Automatic counting function which, in the chip also have analog DC/DC converter to use.
