Description
RESET
OSC2
OSC3
Reset.
Setting this pin to "L" puts the deveice in standby status. At this time,
oscillation stops, AOUT is pulled to GND, and the deveice is initialized.
The MSM6650 family devices have an internal power-on reset. To operate the
power-on reset correctly, power should ramp up within 1 ms. If this is not
possible, apply a
RESET
pulse when power is turned on.
This pin has an internal pull-up resistor.
Busy.
This pin outputs a "L" level during playback. At power-on, this pin is at "H"
level.
XT/
CR
selectable pin.
Set to "H" level when using ceramic oscillation. Set to
"L" level when using RC oscillation.
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
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
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
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"
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.
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.
Phrase Inputs.
Phrase input pins correspoding to playback. The A0 input
becomes invalid when the random playback function is used.
Ground.
Power supply.
Insert a 0.1
m
F or more bypass capacitor between this pin and GND.
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 AR761 or AR762. Set to "L" level or leave
open during playback.
