General Description

EM60000 Series :

The EM60000 series is an 8-bit micro-controller based sound processor IC with an audio function that delivers multi-channel speech and instrument playback. The micro-controller includes a powerful 8-bit RISC CPU that handles most of the speech/melody functions; an 8K word program ROM and a voice ROM with a capacity of up to 2M bytes. It has two speech channels and four melody channels that can be played back simultaneously. The speech synthesis is implemented by software with support for a wide range of sampling rates and different volume levels. The micro-controller also provides real instrument waveforms to ensure good quality audio melody.

The EM60000 provides one 8-bit input port and one 8-bit I/O port with internal pull-low/wake-up functions, and up to three general I/O ports. By software programming, applications such as section combination, trigger mode, output control, keyboard matrix, and other logic functions; can be easily implemented. All these powerful features combined to ensure device versatility to suit a wide range of application possibilities and implementation of user audio concepts.

EM60600S :

EM60600S is an 8-bit micro-controller based sound processor IC with an audio function that delivers multi-channel speech and instrument playback. The micro-controller includes a powerful 8-bit RISC CPU to handle most of the speech/melody functions, an 8K word program ROM, and a voice ROM with 2M bytes. There are two speech channels and four melody channels that can be played back simultaneously. The speech synthesis is implemented by software with support for a wide range of sampling rates and different volume levels. The micro-controller also provides real instrument waveforms to obtain good quality audio melody. The EM60600S offers one 8-bit input port and one 8-bit I/O port with internal pull-low/wake-up functions for user's applications. In addition, three general I/O ports are provided. By programming the micro-controller, applications such as section combination, trigger mode, output control, keyboard matrix and other logic functions can be easily implemented. Together, all these powerful features will inspire the user to realize a wide variety of ideas.
