Internal Mask ROM Voice Synthesis IC, Internal One-Time-Programmable (OTP) ROM Voice Synthesis IC, External ROM Drive Voice Synthesis IC

The MSM6650 family is the successor to OKIs 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 Phrase Control Table functioin. The Phrase Control Table function 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.
