FEATURES
n n n n n Number of LCD drive outputs: 240 Supply voltage for LCD drive: +15.0 to +30.0 V Supply voltage for the logic system: +2.5 to +5.5 V Low power consumption Low output impedance
(Segment mode) n Shift clock frequency Ø 20MHz(MAX.):VDD = +5.0 ± 0.5 V Ø 15MHz(MAX.):VDD = +3.0 to + 4.5 V Ø 12MHz(MAX.):VDD = +2.5 to + 3.0 V n Adopts a data bus system n 4-bit/8-bit parallel input modes are selectable with a mode (MD) pin n Automatic transfer function of an enable signal n Automatic counting function which, in the chip selection mode, causes the internal clock to be stopped by automatically counting 240 bits of input data n Line latch circuits are reset when /DISPOFF active
(Common mode) n Shift clock frequency: 4 MHz (MAX.) n Built-in 240-bit bi-directional shift register (divisible into 120 bits x 2) n Available in a single mode (240-bit shift register) or in a dual mode (120-bit shift register x 2) Ø Y1->Y240 Single mode Ø Y240->Y1 Single mode Ø Y1->Yl20, Y121->Y240 Dual mode Ø Y240->Y121, Yl20->Y1 Dual mode The above 4 shift directions are in-selectable n Shift register circuits are reset when /DISPOFF active
