GENERAL DESCRIPTION
EM57000 is a series of single chip Voice/Dual tone Melody/Dual tone Sound Effect synthesizer ICs. It contains
one 4-bit input port (provided for EM57100 and above), 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 :
EM57001 - 10Kx10 bits,
EM57100 - 16Kx10 bits,
EM57200 - 32Kx10 bits,
EM57300 - 64Kx10 bits,
EM57400 - 128Kx10 bits,
EM57500 - 256Kx10 bits,
EM57600 - 512Kx10 bits,
EM57700 - 1024Kx10 bits.
One 4-bit input port (provided for EM57100 and above), two 4-bit I/O ports.
16x4 bits RAM for EM57001,
32x4 bits RAM for EM57100~EM57500,
128x4 bits RAM for EM57600 and above.
8K (maximum) program ROM for EM57001~EM57500.
32K (maximum) program ROM for EM57600 and above.
One 6-bit timer overflow control.
PCM, ASPCM synthesizer and dual tone melody/sound effect generator.
4K~32K Hz playing speed for voice play-back.
Multiple tempos for dual tone melody/sound effect play-back.
Variable beats for dual tone melody/sound effect play-back.
Multiple levels of volume control.
Fixed current D/A output to drive external connected transistor for voice output.
A pin ( except EM57001, EM57400 ) can be programmed as an IR communication pin which generate 38KHZ
carrier.
