GENERAL DESCRIPTION

EM56000A is a series of single chip dual channel IC with voice synthesizer. The dual channel can be (voice + voice) simultaneously. That contains some input and I/O ports, and a tiny controller. By programming through the tiny controller, users application including section combination, trigger modes, control outputs, IR communication, and other logical function can be easily implemented.

FEATURES

• Single power supply 2.4 V~ 5.5 V.

• Port1 and Port2 with wake-up function, Port3.2 with programmable IR (38 KHz carry) communication function.

• Power down mode for saving power consumption.

• Single ROM for voice program data.

• Readable ROM code data.

• One 6-bit timer overflow control.

• Two stacks for subroutine calling.

• Dual channel output simultaneously : (voice + voice).

• 5-bit ASPCM synthesizer.

• Multiple playing speeds in 2 KHz ~ 32 KHz for voice playback.

• Multiple levels of volume control.

• Fixed current D/A to drive external connected transistor for audio output.
