Supporting Information
Speech playback MCUs(8bit)
HQ-ADPCM is a high quality sound compression technology developed by Ky’s.
Ky’s is a registered trademark of Kyushu Institute of Technology.
Overview
The ML610Q300 group CMOS MCUs with speech output functions utilize a proprietary 8-bit U8 core to achieve superior performance.
A hardware-based high-fidelity speech playback function and high output speaker amp make it possible to provide speech functionality on a single chip, improving sound 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.
Speech output function on a single chip.
Reduce external components, space-saving and improve the reliability
Product Features
Feature 1Speech output function on a single chip

- The low-pass filter reduces noise
- Sound algorithms: HQ-ADPCM,4bit ADPCM2,8bit PCM (non-linear/straight),16bit PCM (straight)
- 1W speaker amplifier (@5V)
- Power supply voltage range: 2.0V to 5.5V
Feature 2High fidelity, high compression HQ-ADPCM makes it possible to reduce the memory capacity
The ML610Q300 group adopts 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.
Feature 3Easy speech playback
Speech Playback Conditions | Sound Code Data Request Interrupt Time*1 |
---|---|
16bit PCM at 16kHz | 250µS |
- *1 : Time from full FIFO to empty
- Achieves speech playback functionality by simply setting sound code data in the sound regist
- Integrating 32-byte FIFO into the sound register makes it possible to extend the interval between sound code data request interrupts
Applications

The ML610Q300 group 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.
speech synthesis utility (Speech LSI Tools)
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.
Speech LSI Tools Operating Environment
- ・Microsoft® ・Windows
Windows 7, Windows 8.1, Windows 10
Note: Compatible with 32bit (x86)/64bit (x64) environments - Processor and memory
Set up according to OS requirements - Hard disk space
1GB usable HDD space - Audio
Windows compatible sound card and speakers - USB Port
Note: Program data is developed separately in the LEXIDE-U16 integrated development environment.
