- By applying three step pipeline RISC architecture, the high performance 8bit CPU ”U8 Core” executing with one instruction per clock cycle is built-in.
- 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 playback condition | Sound data requirement interruption time | |
|---|---|---|
| at 16bitPCM, 16kHz | 250uS | |
| at HQ-ADPCM, 16kHz | 1300uS(max) | |
- High performance sound, high power speaker amplifier
- Adopted HQ-ADPCM improves sound quality.
- HQ-ADPCM can compress 20% of the data compared to the conventional ADPCM.

Sound data creation uses "Speech LSI Utility" which makes test-listening easier by "Reference Board" with built-In microcontroller. 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.
