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.

AOUT

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.

OSC1

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.
