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.
