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.
Key strobe signal.

terminal while one of G7 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, P17 and
AIN6 terminal while one of G8 line keys on key matrix is touched.
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.
Signal similar to P17.
When either G10 line on key matrix is touched, a corresponding signal will be input into P16.
Signal similar to P17.
When either G11 line on key matrix is touched, a corresponding signal will be input into P15.
Signal similar to P17.
When either G12 line on key matrix is touched, a corresponding signal will be input into P14.
Signal similar to P17.
When either G13 line on key matrix is touched, a corresponding signal will be input into AIN7.
Input terminal to judge the model.
The signal out of P04 will be input into AIN6 through G4 line on key matrix. The LSI will judge
the model by this signal.
AH sensor input.
This input is an analog input terminal from the AH sensor circuit, and connected to the A/D
converter built into the LSI.
Used for initial balancing of the bridge circuit (absolute humidity sensor). This input is an analog
input terminal from the AH sensor circuit, and connected to the A/D converter built into the LSI.
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
Terminal not used.
Terminal not used.
Connected to VC.
Terminal not used.
Power source voltage: GND(0V).
The power source voltage to drive LSI is input to VCC terminal.
Connected to VC(-5V).
Internal clock oscillation output.
Output to control oscillation input of XIN.
Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
Terminal not used.
Internal clock oscillation frequency control input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with respect
to XOUT terminal.
Terminal not used.
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.
