[13] System: Increased supply current in Power-down state with digital input pins at high level

This anomaly applies to IC Rev. Revision 2, build codes QDAA-G00.

Symptoms

Supply current is increased in Power-down state.

Conditions

The device is in Power-down state, and the CSN, RX_EN, TX_EN, MODE, SCK, MOSI, or ANT_SEL pin is set high.

Consequences

The supply current may increase up to 500 µA per pin set high.

Workaround

Pull the CSN, RX_EN, TX_EN, MODE, SCK, MOSI, and ANT_SEL pins low in Power-down state. Pull the CSN pin high together with the PDN pin when changing to Program state.
