Please be aware that an important notice concerning availability, standard warranty and use in critical applications of
Murata products and disclaimers thereto appears at the end of this specification sheet.
Stresses in excess of the absolute ratings may cause permanent damage. Functional operation
is not implied under these conditions. Exposure to absolute ratings for extended periods of time
may adversely affect reliability. No damage assuming only one parameter is set at limit at a time
with all other parameters are set within operating condition.

VDD_3.3 (3.3V)
11. POWER ON SEQUENCE
11.1. Case 1: 3.3 V power down after 1.8 V
If the battery source can be removed from the end user device (battery removed, AC/DC plugged
in), this is the recommended power sequence. It will avoid violating the power off sequence by
allowing the 3.3 V rail to shut down after the 1.8 V rail.
Notes:
1. VDDIO_GPIO voltage should match VIO voltage from the host. In some applications,
VDDIO_GPIO may connected to 3.3 V upon Host VIO voltage.
2. In this case, both WLAN_EN and BT_EN on the 1PJ are at 3.3 V due to using the VDD_AO
power rail. If the host VIO voltage is 1.8 V, it must have level shifters to interface with host.
3. All host interface signals must stay floating or low before valid power on sequence (WLAN_EN
and BT-EN goes high).

VDD_3.3 (3.3V)
11.2. Case 2: 1.8 V power down after 3.3 V
If the battery source cannot be removed from the end user device, this is the recommended
power sequence for this application. This sequence allows the software to control the power
on/off sequence.
Notes:
1. VDDIO_GPIO voltage should match VIO voltage from the host. In some applications,
VDDIO_GPIO may connected to 3.3 V upon host VIO voltage.
2. Both WLAN_EN and BT_EN of 1PJ are 1.8 V. If host VIO voltage is 1.8 V, it does
not need level shifter to interface with host.
3. All host interface signals must stay floating or low before WLAN_EN/BT_EN =”high”, and
after WLAN_EN/BT_EN = Low.
