ST8009 Datasheet | Sitronix Technology

DESCRIPTION The ST8009 is a 96-output segment/mon driver IC suitable for driving small/medium scale dot matrix LCD panels, and is used in PDA or electronic dictionary. The ST8009 is good as a segment driver, a mon driver or a mon/segment driver, and it can create low power consumption, high-resolution LCD. The ST8009 have eight modes can selected to set mon and segment numbers by selecting register. The ST8009 also have analog DC/DC converter to use. Low-power liquid crystal display power supply circuit equipped internally. Booster circuit (with Boost ratio of 2X/3X/4X/5X/6X) Regulator circuit Follower circuit Package: 124-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 by programmable. Automatic transfer function of an enable signal Automatic counting function which, in the chip selection mode, causes the internal clock to be stopped by automatically counting 16、32、48、64、 80、96 bits of input data Line latch circuits are reset when XDISPOFF active 2. Features Number of LCD drive outputs: 96 Supply voltage for LCD drive (VOUT): Max +16V Supply voltage for logic system (VDD): +2.5 ~ +5.5V Low power consumption and low output impedance Display duty selectable by internal select register DU2,DU1,DU0 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Abundant mand functions DUTY --1/16 1/32 1/48 1/64 1/80 1/96 1/96 (mon mode) Shift clock frequency: 4 MHz (MAX.)
