2M/4M/8M bit speech synthesis LSI with large scale P2ROMTM
The ML2280x series is a voice synthesis LSI built-in P2ROM 2M/4M/8M for voice and sound data. It has ADPCM2 decoder, D/A converter, low pass filter. ML2280x series realizes all function that is needed to play voice and sound data in one package. P2ROM is LAPIS Semiconductor original programmable ROM technology. Delivery period from ordering will be shorter than current mask ROM products. It can be programmed just before final testing in a manufacturing process. The ML2280x series is very suitable products in system development.
The ML22P808/ML22P804/ML22P802 are OTP version of ML2280x series.
- LONG TIME LARGE NUMBER OF PHRASES AND PLAYBACK MAXIMUM: 524 Second playback time.
- MEMORY BANK SWITCHING FUNCTION
The internal ROM area can be divided into up to four areas.
The use of new voice LSI such as enhancing the number of reproduction phrases is offered. - SHORT DELIVERATION FROM ORDERING FOR MP.
- LINE-UP 2M/4M/8M MEMORY SIZE ( PIN COMPATIBLE).
- LINE-UP OPT VERSION ( PIN COMPATIBLE).
