Overview

8bit ML610Q300 System Block Diagram

ML610Q3xx CMOS MCUs with speech output functions utilize a proprietary 8bit U8 core to achieve superior performance.

A hardware-based high fidelity voice 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 speech playback functionality, low power high-performance U8 core CPU, 3V/5V compatible power supply, and multiple peripheral control functions make it possible to provide speech playback operation in a variety of applications, from battery-equipped to AC-powered devices.

Product Features

Feature 1Speech output function on a single chip

  • The low-pass filter reduces noise
  • Sound algorithms: HQ-ADPCM*1,4bit ADPCM2,8bit PCM (non-linear/straight),16bit PCM (straight)
  • 1W speaker amplifier (@5V)
  • Power supply voltage range: 2.0V to 5.5V

Features 1 of ML610Q300

Feature 2High fidelity, high compression HQ-ADPCM makes it possible to reduce the memory capacity

ML610Q305 and ML610Q306 adopt the newly developed high fidelity, high compression sound algorithm HQ-ADPCM that provides a clearer sound and richer audio range while reducing data size compared with conventional ADPCM, providing a more comfortable listening experience. For example, melodies and sound effects that are degraded with ADPCM and cannot be played with uncompressed PCM can be compressed with HQ-ADPCM, ensuring superior sound quality while reducing memory capacity. Up to 80% compression is possible vs.
4bit ADPCM and 20% compared with 16bit ADPCM.
HQ-ADPCM enables high-fidelity audio compression

Feature 3Easy speech playback

  • Achieves speech playback functionality by simply setting sound code data in the sound regist
  • Integrating 16-byte*1/32-byte*2 FIFO into the sound register makes it possible to extend the interval between sound code data requests interrupts

  • *3 : Time from full FIFO to empty

Applications

The ML610Q300 is ideal for a variety of applications, from compact battery-driven devices including digital thermometers and health care products to AC-driven devices including security devices, housing equipment, and home appliances.

The ML610Q300 provides speech playback solutions for dry cell batteries and AC-powered devices.

speech synthesis utility (Speech LSI Tools)

Easy development with LAPIS Technology's speech synthesis utility

Run the 'Speech LSI Tools' program on a PC to create sound code data using a speech playback MCU.

Speech LSI Tools include a Wave Editor that makes it easy to change (i.e. fade in/out), cut, and connect original sound data (WAVE files) as well as a Speech LSI Utility capable of editing phrases and converting WAVE files to the HQ-ADPCM and ADPCM2 formats.
