Product data sheet
The internal POR pulse will be generated whenever V
than 11 s.
The recommended RESET input pulse length at power-on must be at least 2 ms to ensure
that internal clocks are stable.
The RESET_N pin can be either connected to V
externally controlled by the microcontroller, ASIC, and so on.
