■ NOTICE
The NJW1107 includes Auto-Reset circuit. The NJW1107 requires both analog power supply (AVCC) and digital
power supply (DVDD). Internal digital circuits are initialized by AVCC. The internal reset signal is released after treset
period (0.7sec. < treset < 1.3sec.).
• Power-on Sequence
1. Turn the AVCC on first.
2. Provide the DVDD within 0.7 seconds after the AVCC turns on.
3. Keep the voltage of DVDD below the voltage of AVCC always.
4. Wait for 1.3 seconds and over after the AVCC turns on.
5. Transmit the control data from MCU.
