Description

 

 

 

 

 

 

 

49

AIN5

IN

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.

 

 

 

 

 

 

 

50

AIN4

IN

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.

 

 

 

 

 

 

 

51

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

56

VCC

IN

Power source voltage: GND(0V).

 

 

 

 

The power source voltage to drive LSI is input to VCC terminal.

 

 

 

 

 

 

 

57

OSCSEL

IN

Connected to VC(-5V).

 

 

 

 

 

 

 

58

XOUT

OUT

Internal clock oscillation output.

 

 

 

 

Output to control oscillation input of XIN.

 

 

 

 

 

 

 

59

VSS

IN

Power source voltage: -5.0V.

 

 

 

 

The power source voltage to the LSI is input to VSS terminal. Connected to VC.

 

 

 

 

 

 

 

60

NC

 

Terminal not used.

 

 

 

 

 

 

 

61

XIN

IN

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.

 

 

 

 

 

 

 

 

 

63-66

AIN3-AIN0

IN

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.
