EM57200 Overview

TINY CONTROLLER-BASED SOUND PROCESSOR

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.
