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.
