Voltage Detection Type Reset Circuit (VDET)
This circuit generates an output signal and resets the system when power is first applied and when the voltage drops, i.e.,
when the power supply voltage is less than or equal to the power down detection voltage VDET, which is 3.0 V, typical.
To assure that this function operates reliably, a capacitor must be added to the power supply line so that the power
supply voltage V
DD
rise time when power is first applied and the power supply voltage V
DD
fall time when the voltage
drops are both at least 1 ms. (See Figure 3.)
System Reset
1. Reset method
If at least 1 ms is assured as the supply voltage V
DD
rise time when power is applied, a system reset will be applied
by the VDET output signal when the supply voltage is brought up. If at least 1 ms is assured as the supply voltage
V
DD
fall time when power drops, a system reset will be applied in the same manner by the VDET output signal when
the supply voltage is lowered. Note that the reset is cleared at the point when all the serial data (the display data D1
to D126 and the control data) has been transferred, i.e., on the fall of the CE signal on the transfer of the last
direction data, after all the direction data has been transferred. (See Figure 3.)

2. LC75853NE/NW internal block states during the reset period
CLOCK GENERATOR
Reset is applied and the base clock is stopped. However the OSC pin state (normal or sleep mode) is determined
after the S0 and S1 control data bits are transferred.
COMMON DRIVER, SEGMENT DRIVER & LATCH
Reset is applied and the display is turned off. However, display data can be input to the latch circuit in this state.
KEY SCAN
Reset is applied, the circuit is set to the initial state, and at the same time the key scan operation is disabled.
KEY BUFFER
Reset is applied and all the key data is set to low.
CCB INTERFACE, CONTROL REGISTER, SHIFT REGISTER
Since serial data transfer is possible, these circuits are not reset.
