The N567L120 is an 8-bit µC based speech/melody synthesizer for 1 or 2 battery application.

The N567L120 can implement high sound quality voice and up to 8-ch wavetable melody. It provides at most 16 I/O pins, high sink capability, H/W PWM I/O and IR carrier. In addition, N567L120 build in booster for Vp 3.3V or 4.0V to drive LEDs, PWM mode audio output to drive speaker directly and LVR, Watch Dog Timer to prevent latch-up situation occurring, and LVD to avoid battery over drain. For oscillation, the N567L120 provides either internal oscillation to reduce external component or X’tal interface for high accuracy oscillation frequency.
