Input pin for speaker amplifier.
Input pin for testing.
Fix this pin to “L” level (DGND level). This pin has a pull-down resistor
built in.
Input pin for reset.
At the “L” level, the LSI enters initial state. During reset, the entire
circuitry stops and enters power down state.
power is supplied. After the power supply voltage is stable, drive this
pin to “H” level. Then the entire circuitry can be powered up.
This pin has a pull-up resistor built in.
Output pins for testing.
Leave these pins open.
Ground pins for logic circuitry.
Output pin for command processing status.
This pin outputs “L” level during command processing. Any command
should be entered when this pin is “H” level.
Connect to the crystal or ceramic resonator.
A feedback resistor around 1 MΩ is built in between this pin and the
XTB pin. Use this pin if need to use an external clock.
If the resonator is used, connect it as close to this pin as possible.
Connect to the crystal or ceramic resonator.
When to use an external clock, leave this pin open.
If the resonator is used, connect it as close to this pin as possible.
Power supply pins for logic circuitry.
Connect a capacitor of 0.1μF or more between these pins and DGND
pins.
Serial data output pin for voice ROM interface.
Serial data input pin for voice ROM interface.
Non connected pins. Leave these pins open.
Regulator output pin for internal logic circuitry.
Connect a capacitor recommended between this pin and DGND pin.
Clock output pin for voice ROM interface.
Chip select output pin for voice ROM interface.
At the “L” level, ROM access is available.
Reference voltage output pin for the speaker amplifier built-in.
Connect a capacitor recommended between this pin and DGND pin.
Power supply pin for the speaker amplifier.
Connect a bypass capacitor of 0.1μF or more between this pin and
SPGND pin.
Ground pin for the speaker amplifier.
Positive(+) output pin of the speaker amplifier built-in.
Serves as the LINE output (*3), if built-in speaker amplifier is not used.
Negative(-) output pin of the speaker amplifier built-in.
