LAPIS Technology's Speech Synthesis LSI 4 points!  " Easy" "High sound quality" "Multifunctional" " Space saving"
A high-quality audio solution can be immediately realized on your device.

Lapis' Speech Synthesis LSI is  easy

  • Audio can be output simply by sending simple commands from the microcontrollers.

Lapis' Speech Synthesis LSI has  multiple functions

  • Built-in various functions related to sound. Equipped with fail-safe functions such as abnormal sound detection for vehicles.
  • Multiple voice simultaneous utterance function.
  • Editing ROM function etc.
 

Lapis Speech Synthesis LSI has  high sound quality

  • Sampling frequency up to 48kHz (middleware is typically 8-12kHz).
  • Built-in high performance DAC and filter.

Lapis' Speech Synthesis LSI  saves space

  • Built-in from voice synthesis engine to speaker amplifier, almost no external parts needed.
  • Reduce the risk of failure rate rise by reducing the number of parts.

Please leave "sound making"  Lapis Technology's speech synthesis solution provides one-stop support
for " voice recording"," melody creation"," sound editing"," data writing, and shipping".
You can also select a sound from a "rich audio library"without having to make a sound.
We easily realize "I want to make a sound!".

The International Automotive Task Force (IATF) is a new quality management system standard for the automotive industry that replaces ISO / TS 16949.
Manufactured in IATF 16949 certified facility, we will provide stable and better quality products.

All production sites acquired IATF 16949 certification

Features and functions  Automotive-grade products are equipped with "various fail-safe functions"
Monitors various LSI abnormalities and further enhances the safety of your automotive applications.

Features and functions. 1Built-in speaker amp ensures stable operation at +105°C

Thermal dissipation to the substrate suppresses temperature rise

Automotive-grade Speech Synthesis LSIs are offered featuring a guaranteed operating temperature range of –40°C to +105°C. Integrated memory and speaker amp, together with support for high temperature operation, ensure worry-free use in automotive applications.
The exposed backside die pad enables heat dissipation through the substrate, making it possible to suppress temperature rise within the LSI (including the speaker amp) and ensure stable performance even at an ambient temperature of +105°C.

Features and functions. 2Voice data can be rewritten even after customer's product shipment

Speech Synthesis LSI with built-in Flash memory can be rewritten to ROM via SPI I/F even after customer shipment.

[Flash memory] and [External flash memory] can rewrite audio data via the SPI I/F of the microcontroller.
Voice data can be rewritten in the field after the customer's product is shipped.

Features and functions. 3Equipped with a variety of fail-safe functions

Failure detection from input to speaker terminal is possible. Output becomes "H" when the playback sound is abnormal

Multiple built-in fail-safe functions, such as for detecting playback abnormalities, speaker pin short-circuits, internal LSI temperature, supply voltage drops, and MCU command transfer errors, make it possible to monitor for a variety of LSI failure modes.

Development support tool  

Sound device control kit "SDCK"

This is a development tool that can perform everything from the creation of voice data to the writing of voice data into the voice synthesis LSI, to the trial listening.

* Two types, "SDCK" and "SDCK3", are available depending on the target LSI. For details, refer to “Lineup”.

Software

Speech LSI Utility

A tool to create voice data for speech synthesis LSI.
The created audio data can be simulated on a PC.

Wave Editor

A tool for editing the waveform of original sound data.

SDCB Controller

This is a tool for writing data to the Speech Synthesis LSI on the reference board via the following hardware SDCB and for listening.
Commands to be sent to the Speech Synthesis LSI can be easily operated in GUI format.

Hardware

Sound Device Control Board "SDCB2" "SDCB3"

This tool is to write data to the Speech Synthesis LSI on the reference board and to audition according to the operation of the SDCB Controller.v class="notesBlock mb30">
The reference board is replaceable and supports the Speech Synthesis LSI of the connected reference board.

* Writing for mass production is not covered by the warranty. For mass production, please use the writing shipment at the LAPIS Technology factory or use an on-board writer.

* Two types, "SDCB2" and "SDCB3", are available depending on the target LSI. For details, refer to “Lineup”.

Reference board (sold separately)

It is prepared according to each Speech Synthesis LSI.
Each board is equipped with a speaker jack, so you can easily listen to it just by connecting a speaker.
It can also be used when connected to your system board.
