The MSM66P54 is a one-time-programmable (OTP) version of the MSM6654 speech synthesizer, suitable for evaluation of the MSM6650 family and code development. This part is also suitable for applications requiring small quantities and/or short-term delivery after code completion. The PC-based AR76-202 Speech Development System is used for speech encoding, editing, and programming of the MSM66P54. When compared to the mask-programmed MSM6654 version, the SOP-packaged version of the MSM66P54 is backwards compatible, while the DIP-packaged version has two extra pins for programming. On the DIP version, programming pins CAN either be cut off or left open after programming. DIP pin spacing and location allows insertion of the MSM66P54 into an IC socket intended for the MSM6654. To provide high-quality speech synthesis, all members of the MSM6650 family members implement adaptive differential pulse-code modulation (ADPCM) playback, pulse-code modulation (PCM) playback, 12-bit D/A conversion, and an on-chip -40dB/octave low-pass Filter (LPF). In addition, easy-to-use "beep" Tones a two-channel mixing function, a melody function, a fade-out function, and a random playback function are included. Also, an on-chip edit ROM CAN form sentences by catenating phrases, making external control simpler than before. Four code versions of the MSM66P54 are available. Stand-alone or microcomputer (MCU) Interface modes CAN be selected by using one of the four available codes.
