DESCRIPTION OF LSI
LSI(IZA737DR) : R-330AK / AW
The I/O signal of the LSI(IZA737DR) is detailed in the following table.
Pin No. Signal I/O Description
1-4 AN8-AN11 IN Connected to GND.
5 AVSS IN Connected to VC.
6 TEST IN Connected to VC.
7 X2 OUT Terminal not used.
8 X1 IN Connected to GND.
9 VSS IN
Power source voltage : -5.1V.
VC voltage of power source circuit input.
10 OCS1 IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with respect
to OCS1 terminal.
11 OCS2 OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of OCS2.
12 RESET IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set to
“L” level the moment power is applied, at this time the LSI is reset. Thereafter set at “H” level.
13 MD0 IN Connected to GND.
14 P20 IN
Signal coming from touch key.
When either G12 line on key matrix is touched, a corresponding signal out of P24 - P27, P33,
P34, P35 and P36 will be input into P20. When no key is touched, the signal is held at “H” level.
15 P21 IN
Signal similar to P20.
When either G11 line on key matrix is touched, a corresponding signal will be input into P21.
16 P22 IN
Signal similar to P20.
When either G10 line on key matrix is touched, a corresponding signal will be input into P22.
17 P23 IN
Signal similar to P20.
When either G9 line on key matrix is touched, a corresponding signal will be input into P23.
18 P24 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G8 line keys on key matrix is touched.
19 P25 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G7 line keys on key matrix is touched.
20 P26 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G6 line keys on key matrix is touched.
21 P27 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G5 line keys on key matrix is touched.
22 P30 OUT
Signal to sound buzzer (2.0KHz).
A: key touch sound.
B: Completion sound.
23-24 P31-P32 OUT Terminal not used.
25 P33 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G4 line keys on key matrix is touched.
26 P34 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G3 line keys on key matrix is touched.
27 P35 OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P20 - P23 terminal while one
of G2 line keys on key matrix is touched.
