Overview
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.
