Notes on Controller Transfer of Display Data

Since the LC75836W transfer the display data (D1 to D140) in four separate transfer operations, we recommend that

applications make a point of completing all four data transfers within a period of less than 30ms to prevent

observable degradation of display quality.

OSC Pin Peripheral Circuit

(1) RC oscillator operating mode (control data OC = 0)

An external resistor, Rosc, and an external capacitor, Cosc, must be connected between the OSC pin and GND if

RC oscillator operating mode is selected.

(2) External clock operating mode (control data OC = 1)

When the external clock operating mode is selected, insert a current protection resistor Rg (4.7 to 47kΩ) between

the OSC pin and external clock output pin (external oscillator). Determine the value of the resistance according to

the allowable current value at the external clock output pin. Also make sure that the waveform of the external

clock is not heavily distorted.
