Power source voltage : -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
Terminal not used.
Terminal not used.
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level signal (-5V).
Terminal not used.
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.
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2). The signals
holds "L" level during microwave cooking 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.
Terminal not used.
Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
Terminal not used.
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AIN7, P14, P15, P16 and P17 terminal
while one of G1 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AIN7, P14, P15, P16 and P17 terminal
while one of G2 line keys on key matrix is touched.
