GENERAL DESCRIPTION

The MSM98P05 is a PCM-based voice synthesis IC with built-in 2-Mbit OTP (One Time PROM).

This IC employs OKI nonlinear PCM algorithm and straight PCM algorithm for playback and contains a current mode 10-bit D/A converter and a low-pass filter.

External control can be made easily by the built-in edit ROM that can form sentences by linking phrases. With OKI Voice Analyzing/Editing Tool, the built-in edit ROM can be set up and also the built-in ROM data can be created and evaluated easily.

With the stand-alone mode/microcontroller interface mode switching pin, the MSM98P05 can support various applications.
