Overview


ML610300 series CMOS MCUs with speech output function utilizes a proprietary 8bit U8 core to achieve superior performance.
A hardware-based high fidelity speech playback function and high output speaker amp make it possible to provide voice functionality on a single chip, improving audio quality, simplifying control, and maximizing MCU performance.
The optimized combination of high fidelity voice playback functionality, low power high performance U8 core CPU, 3V/5V compatible power supply, and multiple peripheral control functions make it possible to provide voice playback operation in a variety of applications, from battery-equipped to AC-powered devices.

Features


Features1
Speech output function on a single chip
  • Noise reduction by low pass filter
  • Speech algorithm: ADPCM2 and high quality sound data
    compression HQ-ADPCM
  • Speaker amplifier of 1W at 5V
  • Power supply voltage range: 2.2V to 5.5V
Features2
High performance CPU" U8 Core "
  • Original RISC CPU achieved one-instruction one cycle by 3-stage pipelined architecture.
Features3
Easy speech playback
  • Speech playback is easily implemented by only setting speech data into speech register.
  • Since FIFO for 4 words are installed in sound register, the interval for sound data requirement interruption can be set longer.

speech synthesis utility(Speech LSI Utility)

Sound data creation uses "Speech LSI Utility" which makes test-listening easier by "Reference Board" with built-In microcontroller.
This tool enables users to convert a WAV format file to LAPIS Semiconductor’s original ADPCM2 format and to edit phrases.
In addition, users can easily manipulate voice data such as sound clipping/connection and fade-in/fade-out.
The development of application program uses "IDEU8 Integrated Development Environment" with an intelligible graphical user interface which makes more efficient of a sequence of programing to debugging.
Moreover, using compact "On-chip Debug Emulator µEASE" and "Flash programming software (FWµEASE and MWµEASE)", writing sound data and application program into Flash memory, and mounting make evaluation possible.
