Description

Initial

value

IOVDD

Flash memory interface power supply pin.

Connect to DVDD pin even when not using flash memory interface.

Connect a bypass capacitor between this pin and the DGND pin.

—

VDDR

3.0V regulator outputs. Used as a power supply for flash memory.

Connect a capacitor between this pin and DGND pin as close as

possible.

Connect this pin to the DVDD pin when DVDD = 2.7 to 3.6V.

SAD0

2C slave address select pin.

—

SAD1

2C slave address select pin.

—

SAD2

2C slave address select pin.

—

XTB

Negative

Crystal or ceramic resonator connection pin.

When an external clock is used, leave it open and capacitor is not

required when a crystal or ceramic resonator is connected.

When using a resonator, connect it as close as possible.

Leave it open when not in use.

Positive

Crystal or ceramic resonator connection pin.

A feedback resistor of about

1MΩ is built in between the XT pin and

the XTB pin.

To use an external clock, input from this pin. Delete the capacitor

when a crystal or ceramic resonator is connected.

When using a resonator, connect it as close as possible.

Leave it open when not in use.

DVDD

Digital power supply pin.

Connect a bypass capacitor between this pin and the DGND pin.

—

VDDL

2.5V regulator output pin.

Used as internal power supply.

Connect a capacitor between this pin and DGND pin as close as

possible.

FB1

Analog input pin 1 for playback sound error detection.

FB2

Analog input pin 2 for playback sound error detection.

LOUT

This pin is used exclusively for line amplifier output.

Reference voltage output pin for the built-in speaker amplifier.

Connect a capacitor between this pin and SPGND pin.

AIN

Speaker amplifier analog signal input pin.

Initially, input is disabled.

SPVDD

Power supply pin for speaker amplifier.

Connect a bypass capacitor between this pin and the SPGND pin.

—

SPOVDD

Power supply pin for the speaker amplifier output circuit.

Set it at the same potential as the SPVDD pin.

—

SPGND

Speaker amplifier ground pin.

—

SPOGND

Ground pin for the speaker amplifier output circuit.

Set it at the same potential as the SPGND pin.

—

SPP

Positive output pin of the speaker amplifier.

Line amplifier outputs are also available with AMODE command.

SPM

Negative output pin of the speaker amplifier.

Hi-Z

*1 Initial value at reset input and power-down. The pin whose IO is "I" indicates a fixed level from outside.
