N567G121 Overview
The N567Gxxx is a powerful microcontroller (uC) dedicated to speech and melody synthesis applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the N567Gxxx can synthesize 4-channel speech+melody simultaneously. The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM.
