(HT86030 / HT86070) Voice Synthesizer 8-Bit MCU The HT86030/HT86070 series are 8-bit high performance microcontroller with voice synthesizer and tone generator. The HT86030/HT86070 is designed for applications on multiple I/Os with sound effects, such as voice and melody. It can provide various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator. It has a single built-in high quality, D/A output. There is an external interrupt which can be triggered with falling edge pulse or falling/rising edge pulse. The HT86030/HT86070 is excellent for versatile voice and sound effect product applications. The efficient MCU instructions allow users to program the powerful custom applications. The system frequency o... |
