HT37B90数据手册Holtek中文资料规格书

描述 Description

The device is an 8-bit high performance RISC architecture microcontroller specifically designed for various Music and ADPCM applications. It provides an 8-bit MCU and 16-channel wavetable synthesizer. It has a integrated 8-bit micro controller which controls the synthesizer to generate the melody by setting the special register. A Power-down function is included to reduce power consumption.
