ST8012 Datasheet | Sitronix Technology

DESCRIPTION The ST8012 is a 120-output segment/mon driver IC suitable for driving small/medium scale dot matrix LCD panels, and is used in PDA or electronic dictionary. The ST8012 is good as a segment driver or a mon driver or a mon/segment driver, and it can create a low power consuming, high-resolution LCD. The ST8012 have eight modes can selected to set mon and segment numbers by select pin. The ST8012 Low-power liquid crystal display power supply circuit equipped internally. Booster circuit (with Boost ratio of 2X/3X/4X/5X/6X) Abundant mand 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. 2. FEATURES Number of LCD drive outputs: 120 Supply voltage for LCD drive: Max +16V Supply voltage for the logic system: +2.5 to +5.5 V Low power consumption and low output impedance SEL2,SEL1,SEL0 DUTY 0 0 0 --0 0 1 1/32 0 1 0 1/48 0 1 1 1/64 1 0 0 1/80 1 0 1 1/96 1 1 0 1/112 1 1 1 1/120 BIAS Segment mode 1/6 or 1/5 1/7 or 1/5 1/9 or 1/7 1/9 or 1/7 1/10 or 1/8 1/11 or 1/9 1/11 or 1/9 Displa y duty select able by select pin .. selection mode, causes the internal clock to be stopped by automatically counting 88、72、56 、40、 24、8 or 120 bits of input data Line latch...
