Pin No. Signal I/O Description
19-21 P27-P25 OUT Terminal not used.
22-26 P24-P20 IN Terminal not used.
27 P47 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).
28 P46 OUT Terminal not used.
29 P45 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.
30 P44 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.
31 P43 Terminal not used.
32 CNTR0 OUT Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
33 P41 OUT Terminal not used.
34 INT0 IN Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
35 P07 OUT 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.
36 P06 OUT 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.
37 P05 OUT 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 G3 line keys on key matrix is touched.
38 P04 OUT 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 G4 line keys on key matrix is touched.
39 P03 OUT 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 G5 line keys on key matrix is touched.
40 P02 OUT 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 G6 line keys on key matrix is touched.
41 P01 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AIN7, P14, P15, P16, P17
and AIN6 terminal while one of G7 line keys on key matrix is touched.
42 P00 OUT 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 G8 line keys on key matrix is touched.
43 P17 IN Signal coming from touch key.
When either G9 line on key matrix is touched, a corresponding signal out of P00-P07 will
be input into P17. When no key is touched, the signal is held at "H" level.
44 P16 IN Signal similar to P17.
When either G10 line on key matrix is touched, a corresponding signal will be input into P16.
45 P15 IN Signal similar to P17.
When either G11 line on key matrix is touched, a corresponding signal will be input into P15.
20.0 msec.
During cooking
H : GND
L : -5V
