EASY SOUND - EM56000 SERIES
TINY CONTROLLER-BASED VOICE SYNTHESIZER
GENERAL DESCRIPTION
EM56000 is a series of single chip Voice synthesizer ICs. It contains one 4-bit input port (not for EM56001), two 4-bit I/O ports and a tiny controller. User's applications, such as section combination, trigger modes, control outputs, keyboard matrix, and other logic functions, are easily implemented by programming through its tiny controller.
FEATURES
· Single power supply 2.4 V ~ 5 V. · Wide range of ROMs : EM56001 - 10Kx10 bits, EM56100 - 16Kx10 bits, EM56200 - 32Kx10 bits, EM56300 - 64Kx10 bits. · One 4-bit input port (not for EM56001), two 4-bit I/O ports. · 16x4 bits RAM for EM56001, 32x4 bits RAM for EM56100, EM56200, EM56300. · 8K (maximum) program ROM. · One 6-bit timer overflow control. · ASPCM, PCM voice synthesizer. · 4K~32K Hz playing speed for voice play-back. · Multiple levels of volume control. · Fixed current D/A output to drive external connected transistor for voice output. · A pin (P3.2) for EM56100, EM56200, EM56300 can be programmed as an IR communication pin which generate 38KHZ carrier.
