HT86030/HT86070 -- Voice Synthesizer 8-Bit MCU

General Description

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 of HT86030/HT86070 can be up to 8MHz under 2.4V and include a HALT function to reduce power consumption.
