EM61001

Specifications* for EM61000 8-Channel Wave-Table Music Synthesizer 1. GENERAL DESCRIPTION EM61000 series is an 8-bit micro-controller based music processor IC with audio function that delivers 8 channels instrument playback. The micro-controller includes a powerful 8-bit RISC CPU to handle most of the music functions, an 8K words program ROM, and a voice ROM that extends up to 512K bytes. There are eight melody channels that can be played back simultaneously. The micro-controller provides real instrument waveforms to obtain good quality audio melody. The EM61000 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, up to 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. 2. FEATURES Operating voltage: 2.4 ~ 5.5V. 8-bit RISC CPU. Three general-purpose timers. 8K word program ROM access and 8-level stacks. Multi melody channels can be played simultaneously (8 channels for EM61100~ EM61400, 4 channels for EM61001 and EM61002). On chip voice ROM will extend up to 512K Bytes. Uses real instrument waveforms for good quality audio melody. Built-in 8-bit by 8-bit hardware multiplier with 16-bit result. One 8-bit input port and one 8-bit I/O port with...
