Fast Vcc ramp after device power up may cause a reset
At initial power-up, after Vcc crosses the brownout threshold and reaches a constant level, an abrupt ramp of Vcc at a rate dV/dT > 1V/100us can cause a brownout condition to be incorrectly detected even though Vcc does not fall below the brownout threshold. This causes the device to undergo a reset.
Use a controlled Vcc ramp to power up the device.
