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.
