Preliminary
EASYSOUND- EM57P300SERIES
TINYCONTROLLER-BASED
SOUNDPROCESSOR
GENERAL DESCRIPTION
EM57P300 is a tiny-controlled-based voice/dual tone melody/dual tone sound effect Ics which contain all the
function of EM57000 series and has an OTP (One Time Programmable) ROM inside.
FEATURES
• EM57P300 – ROM : 64k x 10 bits (21 sec@6K sample rate).
• Working Voltage 2.4V ~ 5.1V.
• One 4-bit input port, two 4-bit I/O ports, and 32x4 bits RAM.
• 8k (maximum) program ROM.
• One 6-bit timer overflow control.
• 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.
