This anomaly applies to IC Rev. Engineering A, build codes SICA-BAA.
Symptoms
The 1.8 V GPIOs MAGPIO[0,1,2] and MIPI RFFE[SCLK, SDATA] have a higher voltage than specified for the first millisecond.
Conditions
Use of any of the 1.8 V GPIOs:
- MAGPIO[0,1,2]
- SCLK
- SDATA
Consequences
Voltage increase up to 2.2 V for 1 ms after reset.
Workaround
None.
Note: This item will be fixed on the production version of nRF9160-SICA.
