N567LXXX DATA SHEET
1. GENERAL DESCRIPTION
The N567Lxxx is an 8-bit uC based speech/melody synthesizer for 1 or 2 battery application.
The N567Lxxx 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, N567Lxxx
build in booster for VP 3.3V or 4.2V 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 N567Lxxx provides either internal oscillation to reduce external component or
Xtal interface for high accuracy oscillation frequency.
The N567Lxxx family contains several items with different playback durations as shown below:

124 sec.
N567L160

Note: *: The duration time is based on 4-bit NM4 at 6 KHz sampling rate. The firmware library have been excluded from
user’s ROM space for the duration estimation.
