Playbacks “human voice” and “sound effect” in very clear sound

  • Abundant Market Achievement: This product has been used in a variety of applications, such as toys and cars, for around 30 years.
  • LAPIS Semiconductor offers a wide selection of products, focusing on superior sound quality ADPCM method.
  • LAPIS Semiconductor suppots the customer to create sound, including recording, sample creation, and sound adjustment.


LAPIS Semiconductor's Speech Synthesis LSI collects wide products holding the top track record(*) in the domestic market in Japan. The various built-in memory types can be selected according to the customer requiring memory size.
•Speech Synthesis LSI Series with Built-in Large Capacity P2ROM™
This series is the speech synthesis LSI equipped with LAPIS Semiconductor's original P2ROM™. After being assembled, these products wait for an order from customers, and then sound data is written. This process can significantly reduce the sample creation time and mass production TAT. It is suitable for a long time sound playback such as audio instruction

•Speech Synthesis LSI Series for Automotive Systems
ML2257□series and ML22Q553 guarantee operation at +105℃ with the 4ch mixing function and speaker amplifier implemented. Also, the internal temperature of LSI and a voltage drop in the power supply are detected as a fail-safe. More functions necessary for car installation are also included, such as a detection of CPU command send error and over-current shutdown circuit. FlashROM and MaskROM types are available with full compatibility between them.
