EASY SOUND - EM57000 SERIES  
TINY CONTROLLER-BASED  
SOUND PROCESSOR  
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.
