I/O
IN
Primary input voltage watching terminal.
The LSI is watching the primary input voltage through this terminal.
IN
Input terminal to change the specification according to the model.
IN
Temperature measurement input: OVEN THERMISTOR.
By inputting DC voltage corresponding to the temperature detected by the thermistor, this input
is converted into temperature by the A/D converter built into the LSI.
IN
Input signal which communicates the door open/close information to LSI.
Door closed; "H" level signal(0V).
Door opened; "L" level signal(-5V).
IN
Turminal not used.
IN
Turminal not used.
Timing signal output terminal for temperature measurement(OVEN THERMISTOR).
"L" level (-5V) : Thermistor OPEN timing.
"H" level (GND) : Temperature measuring timing.
Oven lamp and turntable motor driving signal. (Square Waveform : 60Hz)
To turn on and off the shut-off relay(RY1). The
square waveform voltage is delivered to the
relay(RY1) driving circuit.
IN
Power source voltage: -5V.
VC voltage of power source circuit input.
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set to "L"
level the moment power is applied, at this time the LSI is reset. Thereafter set at "H" level.
Top heating element driving signal.
To operate the solid-state relay for driving the top heating element.
Side heating element driving signal.
To operate the solid-state relay for driving the top heating element.
IN
Power source voltage: -5V.
VS voltage of power source circuit input.
IN
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with respect
to Xout terminal.
Internal clock oscillation frequency control output.
Output to control oscillation input of Xin.
IN
Power source voltage: 0V.
VC voltage of power source circuit input. Connected to GND.
Signal to sound buzzer.
A: Tact switch touch sound.
B: Completion sound.
C: When the oven stops so that the food can be
checked in Automatic cooking mode.
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay(RY2). In 100%
power operation, the signals holds "L" level
during microwave cooking and "H" level while
not cooking. In other cooking modes (90%,
80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%,
0%) the signal turns to "H" level and "L" level in
repetition according to the power level.
Cooling fan motor driving signal.
To turn on and off shut-off relay(RY5). "L" level
during fan motor driving; "H" level otherwise
