N584Hxxx Data Sheet
1. General Description
N584Hxxx is a 4-bit microcontroller-based speech synthesizer with PWM mode output
to drive the speaker directly. The synthesizer contains one voice-channel and/or dual tone
melody. It has Ultra I/OTM to simplify the procedure of defining the output pattern, besides, it
also includes 4-level Low Voltage Detection function. The N584Hxxx family contains several
devices with different playback duration shown as below:
