[37] POWER: Current consumption might increase after pin reset or power cycle

nRF54LM20A Revision 1 Errata

This anomaly applies to Revision 1, build code PAAA-B00.

It was inherited from the previous SoC revision Engineering B.

Symptoms

Current consumption is higher than expected in System OFF mode.

Conditions

The device is entering System OFF mode too soon after a pin reset or power cycle.

Consequences

Current consumption is higher than expected.

Workaround

Apply the following workaround:
  1. Perform the following code: *(volatile uint32_t *) 0x5005340C =1;
  2. Ensure that 40 CPU cycles are executed before entering System OFF mode.
