[10] LTE Modem: MAGPIO and MIPI RFFE - high initial voltage

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.
