Preliminary
EASY SOUND - EM55000SERIES
TINYCONTROLLER-BASEDSYNTHESIZER
EM55000 series is a series of 3 to 340 seconds single chip high quality voice synthesizer IC which contains one
4-bit Input port (provided for EM55100 and above), three 4-bit I/O ports and a tiny controller. By programming
through the tiny controller, user's application includes section combination, trigger mode, control outputs,
keyboard matrix and other logic function can be easily implemented.
