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.
