24 P25 OUT 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.
(ON and OFF times for other power level.)
25-26 P26-P27 OUT Terminal not used.
27-29 P30-P32 OUT Terminal not used.
30-34 P33-P37 OUT Used for initial balancing of the bridge circuit (absolute humidity sensor).
35 CVCC IN Connected to GND.
36 VSS IN Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC
37-38 V3-V2 IN Terminal not used.
39-40 V1-V0 Power source voltage input terminal.
Standard voltage for LCD. Connected to GND.
41 VCC IN Power source voltage: GND (0V).
The power source voltage to drive the LSI is input to VCC terminal.
42-45 COM4-COM1 OUT Terminal not used.
46-65 SEG1-SEG20 OUT Terminal not used.
66-79 P74-P91 OUT Data output terminal to LCD driver IC3
80-85 SEG35-SEG40 OUT Terminal not used.
86 P40 OUT Terminal not used.
87 P41 IN Signal similar to AN10.
When either G13 line on key matrix is touched, a corresponding signal will be input into P41.
88 P42 INSignal similar to AN10.
When either G12 line on key matrix is touched, a corresponding signal will be input into P42.
89 IRQ0 IN Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
90 AVCC IN A/D converter power source voltage.
The power source voltage to drive the A/D convertor built into LSI. connected to GND.
91 AN0 IN Used for initial balancing of bridge circuit (absolute humidity sensor). This input is an
analoge input terminal from the AH sensor circuit, and connected to the A/D converter
built into the LSI.
92 AN1 IN AH sensor input.
This input is an analoge input terminal from the AH sensor circuit, and connected to the
A/D converter built into the LSI.
