For full specifications, please contact your nearest Oki office or representative. FEDL6650-03 GENERAL DESCRIPTION The MSM6650 family is the successor to OKI's MSM6375 family. To ensure high-quality voice synthesis,theMSM6650familymembersofferadaptivedifferentialpulse-codemodulation(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 StandaloneModeorMicrocontrollerInterfaceMode.InMicrocontrollerInterfaceMode,serialinput 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.
