EASY SOUND - EM58P300SERIES
TINYCONTROLLER-BASED
DUALCHANNELSOUNDPROCESSOR
GENERAL DESCRIPTION
EM58P300 is a tiny-controller-based voice synthesizer/dual tone melody/dual tone sound effect IC which contains
all the function of EM58000 series and has an OTP (One Time Programmable) ROM inside.
FEATURES
• EM58P300 – ROM : 64k x 10 bits (21 sec@6K sample rate).
• Single power supply 2.4V ~ 5.5V.
• Port1 and Port2 with wake-up function, Port3.2 with programmable IR (38KHz carry) communication function.
• Power down mode for saving power consumption.
• Single ROM for voice, melody, sound effect and program data.
• Readable ROM code data.
• One 6-bit timer overflow control.
• Two stacks for subroutine calling.
• Dual channel output simultaneously : (voice + voice), (voice + dual tone melody) or (voice + dual tone sound
effect).
• 5-bit ASPCM synthesizer.
• Dual tone melody/sound effect generator with programmable envelope.
• Multiple playing sppeeds in 2KHz ~ 32KHz for voice playback.
• Multiple tempos and variable beats for dual tone melody/sound effect play-back.
• Multiple levels of volume control.
• Fixed current D/A to drive external connected transistor for audio output.
