Voice Synthesis IC with Built-in 2-Mbit OTP ROM
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.
The products with build-in OTP are suited to applications to be produced in small quantities in
a wide variety or in short delivery time. Demand like these, that is, production in small quantities
in a wide variety and delivery with an early deadline is what the MSM9800 family of products
with built-in mask ROM cannot meet.
