Description

The MSM6655 is the successor to OKI's MSM6375 family. To ensure high-quality voice synthesis, the MSM6655 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 of MSM6655 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 MSM6655 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 MSM6655 includes an internal mask ROM version, internal one-time-programmable (OTP) ROM version, and external ROM version. The features of the MSM6655 devices are as follows.
