th e w ire le ss co m m un ic at io n s ol ut io n p ro vi de r AR3301 4k c ol or s tn d riv er & c on tro lle r ic general description 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. fea tures * lcd drive circuit segment outputs: 384 outputsspecial 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: 162, 160, 144, 132, 128, 1 12, 96, 80, 72, 64, 56, 48, 40, 32, 24, 16 * 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
