OUT
Terminal not used.
14
CNTR0
OUT
Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
15
P53
OUT
Terminal not used.
16
P52
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.
17-18
P51-P50
OUT
Terminal not used.
19
P47
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.
(ON and OFF times for other power level.)
20
P46
IN
Signal coming from touch key.
When either G11 line on key matrix is touched, a corresponding signal out of P20 - P26
will be input into P46. When no key is touched, the signal is held at "H" level.
21
P45
IN
Signal similar to P46.
When either G10 line on key matrix is touched, a corresponding signal will be input into
P45.
22
P44
IN
Signal similar to P46.
When either G9 line on key matrix is touched, a corresponding signal will be input into
P44.
23
P43
IN
Signal similar to P46.
When either G8 line on key matrix is touched, a corresponding signal will be input into
P43.
24
INT0
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
25
P41
OUT
Terminal not used.
26
P40
IN
Connected to GND through the pull-down resistor R100.
27
RESET
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set
"L" level the moment power is applied, at this time the LSI is reset. Thereafter set at "H"
level.
28-29
P71-P70
OUT
Terminal not used.
30
XIN
IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XOUT terminal.
31
XOUT
OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of XIN.
Pin No.
