LC75813E, LC75813T 1/3, 1/4-Duty General-Purpose LCD Driver Overview The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block powersupply voltage. Features Switching between 1/3 duty and 1/4 duty drive techniques under serial data control. Switching between 1/2 bias and 1/3 bias drive techniques under serial data control. Up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed. Serial data input supports CCB* format communication with the system controller. Serial data control of the power-saving mode based backup function and all the segments forced off function. Serial data control of switching between the segment output port and the general-purpose output port functions. Serial data control of frame frequency for common and segment output waveforms. High generality, since display data is displayed directly without decoder intervention. Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block powersupply voltage.) The INH pin can force the display to the off state.

The controller should then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at power on. (See Figures 3 and 4.) Notes on the Power On/Off Sequences Applications should observe the following sequences when turning the LC75813E and LC75813T power on and off. • At power on: Logic block power supply (VDD) on → LCD driver block power supply (VLCD) on • At power off: LCD driver block power supply (VLCD) off → Logic block power supply (VDD) off However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off at the same time. 1. 1/3 duty t2 t1 t3 VDD VLCD INH VIL tc CE VIL Display and control data transfer D1 to D87 Internal data P0 to P3 DR, DT, FC, SC, BU Undefined Defined Undefined Internal data (D88 to D174) Undefined Defined Undefined Internal data (D175 to D261) Undefined Defined Undefined Notes: t1 ≥ 0 t2 > 0 t3 ≥ 0 (t2 > t3) tc .......10µs min.
