| The wireless communication solution provider 4K Color STN Driver & Controller IC GENERAL DESCRIPTION AR3301 AR3301 is a single chip driver and controller device for dot matrix LCD (liquid crystal display) display systems. This chip can be directly connected to a microprocessor, accepts serial or 8/16bit parallel display data from the microprocessor, stores the display data in a built-in display RAM and generates LCD driving signals. AR3301 has 128 X RGB segment outputs and 162 common outputs, so that it can drive 128X162 dots 256/4096-color STN LCD panel. AR3301 is best suited to drive LCD systems for batteryoperated, handheld information equipment by ensuring low power consumption and a wide range of operating voltages. FEATURES *LCD drive circuit Segment outputs: 384 outputs Special segment outputs: 6 outputs Common outputs: 162 outputs *Display RAM capacity 128 x 162 x12 = 248,832 bits *Display functions gradation: 16 gradations can be selected from 32 gradations By PWM control. Monochrome: 162 x128 (8 gradation available) Partial display: a specific part of the graphic display area can be displayed. *Applicable duty ratios: 40, 32, 24, 16 162, 160, 144, 132, 128, 112, 96, 80, 72, 64, 56, 48, *MPU interface: 8bit parallel bi-directional interface with 80-family and 68family MPU: serial interfaces (only write operation) available. *LCD drive power circuit builtin booster circuit: two, three, four, five, six or seven times voltage Boost is available. *Builtin electronic volume: controllable in 128 steps The wireless communication solution provider *Builtin voltage converter: generates LCD drive voltages (V0, V1, V2, V3, V4) based on the boosted voltages *Builtin constant voltage generator circuit *Selectable bias ratio: select from 1/12, 1/11, 1/10, 1/9, 1/8, 1/7, 1/6, and 1/5 using commands. *Various function set: display data read/write setting LCD alternated signal cycle setting display starting-line display ON/OFF display controls of normal and reverse modes setting common startingline increment control of display RAM addresses readmodifywrite control internal register read power saving modes *Power source: supply voltage for logic system: +1.7 to +3.3 V LCD drives voltage: +5.0 to +18 V *Operating temperature: 30 to +85C * Package type: COF / COG The wireless communication solution provider CHIP COF COG |
