GENERAL DESCRIPTION
The MSM6650 family is the successor to OKI's MSM6375 family. To ensure high-quality voice
synthesis, the MSM6650 family members offer adaptive differential pulse-code modulation (ADPCM)
playback, pulse-code modulation (PCM) playback, 12-bit D/A conversion, and on-chip –40 dB/
octave low-pass filter (LPF).
The conventional "beep" tones and 2-channel playback are now easier to use. OKI has added
additional functions such as melody play, fade-out, and random playback. OKI has improved
external control by adding an Edit ROM. The Edit ROM can be used to form sentences by linking
phrases.
The MSM6650 family members can support a variety of applications as it can function in either
Standalone Mode or Microcontroller Interface Mode. In Microcontroller Interface Mode, serial input
control is available. Serial input control minimizes the number of microcontroller port pins required
for voice synthesis control. The MSM6650 family includes an internal mask ROM version, internal
one-time-programmable (OTP) ROM version, and external ROM version. The features of the
MSM6650 family devices are as follows.
• MSM6652/53/54/55/56-xxx
These devices are single-chip voice synthesizers with an on-chip mask ROM using the CMOS
technology.
Standalone Mode or Microcontroller Interface Mode can be selected by mask option.
• MSM6652A/53A/54A/55A/56A/58A-xxx
The trial production period for these devices is shorter than those described above. These devices
are suitable for developing prototype models and concept demonstration of new products.
• MSM66P54-xx, MSM66P56-xx
The device is a single-chip CMOS voice synthesizer with one-time-programmable (OTP) ROM.
Standalone and Microcontroller Interface Modes are selected by using a code (01-04).
The user can easily write voice data using the development tool AR761 or AR762, or P54 adapter.
Unlike the mask ROM version, the OTP version is suited to applications which requires a small lot
production of different type devices or short delivery time.
• MSM6650
The MSM6650 device can directly connect external ROM or EPROM of up to 64 Mbits, which
stores voice data.
This device is ideally suited to an evaluation IC for the MSM6650 family because its circuit
configuration is identical to those of the mask ROM-based and OTP version devices.

Description
RESET
Reset. Setting this pin to "L" puts the LSI in standby status. At this time,
I oscillation stops, AOUT is pulled to GND, and the deveice is initialized.
This pin has an internal pull-up resistor.
BUSY
Busy. This pin outputs a "L" level during playback. At power-on, this pin is at "H"
O
level.
XT/CR
XT/CR selectable pin. Set to "H" level when using ceramic oscillation. Set to
I
"L" level when using RC oscillation.
AOUT
OSC1
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
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.
OSC2
Oscillator 2. This pin is a ceramic oscillator connection pin when using a
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.
OSC3
RND
Oscillator 3. Leave open if using a ceramic oscillator. This pin is the RC
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"
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.
SW0-SW3 I
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.
A0-A2
Phrase Inputs. Phrase input pins correspoding to playback. The A0 input
I
becomes invalid when the random playback function is used.
GND
VDD
TEST
VPP
— 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.
PGM
Interface with voice analysis edit tool AR203 or AR204. Set to "L" level or leave
I
open during playback.
