EM58P300 – ROM : 64k x 10 bits (21 [email protected] 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.
