Sample Application Circuit 4
Note:
*
8.Add a capacitor to the power supply line so that the power supply voltage V
DD
rise time when power is applied and the power supply voltage V
DD
fall time when power drops are both at least 1 ms, as the LC75853NE/NW is reset by the VDET.
*
9.The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 k
) appropriate for the capacitance of the
external wiring so that signal waveforms are not degraded.
Notes on transferring display data from the controller
The display data (D1 to D126) is transferred to the LC75853NE/NW in three operations. All of the display data should
be transferred within 30 ms to maintain the quality of the displayed image.
Notes on the controller key data read techniques
1. Timer based key data acquisition
