N584H170 Overview
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.
