Pin

Symbol Type

Description

Reset. Setting this pin to "L" puts the LSI in standby status. At this time,

17

RESET I oscillation stops, AOUT is pulled to GND, and the deveice is initialized.

This pin has an internal pull-up resistor.

20

BUSY

Busy. This pin outputs a "L" level during playback. At power-on, this pin is at "H"

O level.

22

XT/CR

XT/CR selectable pin. Set to "H" level when using ceramic oscillation. Set to

I

"L" level when using RC oscillation.

23

AOUT O Sound Output. This is the synthesized output pin of the internal low-pass filter.

Oscillator 1. This pin is a ceramic oscillator connection pin when using ceramic

2

OSC1 I oscillation. This pin is an RC connection pin when using RC oscillation.

When using an external clock, use this pin as the clock input.

Oscillator 2. This pin is a ceramic oscillator connection pin when using a

3

OSC2 O ceramic oscillator. This is an RC connection pin when using RC oscillation.

Leave open if using an external clock. OSC2 outputs a "L" level in standby status.

Oscillator 3. Leave open if using a ceramic oscillator. This pin is the RC

5

OSC3 O connection pin when using RC oscillation. When RC oscillation is selected, OSC3

outputs a "H" level in standby status.

Random Playback. Random playback starts when the RND pin is set to a "L"

8

RND

I level. At the fall of RND, addresses from the random address playback circuit

inside the IC are fetched. Set to a "H" level if random playback is not used.

This pin has an internal pull-up resistor.

Phrase Inputs. These pins are phrase input pins corresponding to playback.

9-12

SW0-SW3 I If the input changes, SW0 to SW3 pins capture address data after 16 ms and

speech playback commences. These pins have internal pull-down resistors.

— Ground.

— Power supply. Insert a 0.1mF or more bypass capacitor between this pin and GND.

I Test Mode. Set to "H" level. This pin has an internal pull-up resistor.

Power supply used when writing data to internal OTP ROM. Leave open or set to

—

"H" level during playback.

Interface with voice analysis edit tool AR203 or AR204. Set to "L" level or leave
