P70
OUT
Oven lamp, fan motor and turntable motor driving signal
To turn on and off shut off relay (RY1). The
square waveform voltage is delivered to the
RY1 driving circuit and RY2 control circuit.
42
P71
OUT
Terminal not used.
43
P72
OUT
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2). The
signals holds “L” level during microwave cook-
ing and “H” level while not cooking. In other
cooking modes (variable cooking) the signal
turns to “H” level and “L” level in repetition
according to the power level.
44
AVDD
IN
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI. Connected to GND.
45-48
AIN5-AIN2
IN
Terminal to change cooking input according to the Model.
By using the A/D converter contained in the LSI, DC voltage in accordance with the Model
in operation is applied to set up its cooking constant.
49
AIN1
IN
This is the terminal to detect the voltage of the signal coming from the touch key.
50
AIN0
IN
Signal similar to AIN1.
51
AVSS
IN
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI.
52
P11
IN
To input signal which communicates the door open/close information to LSI.
Door close “H” level signal (0V). Door open “L” level signal (-5V).
53
P10
OUT
Terminal not used.
54

while one of G3 line keys on key matrix is touched.
57
INTP0
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
58
P26
OUT
