41 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 P33 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G1 line keys on key matrix is touched.
55 P32 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G2 line keys on key matrix is touched.
56 P31 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
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 Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G4 line keys on key matrix is touched.
59 P25 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G5 line keys on key matrix is touched.
60 P24 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G6 line keys on key matrix is touched.
61 P23 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G7 line keys on key matrix is touched.
62 P22 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G8 line keys on key matrix is touched.
