1 The current consumption figures in Modem-sleep mode are for cases where the CPU is powered on and

the cache idle.

2 When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. Therefore, current

consumption changes accordingly.

3 In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU

load and the peripherals used.

1 JEDEC document JEP157 states that 250 V CDM allows safe manufacturing with a standard ESD control

process.

2 JEDEC document JEP155 states that 500 V HBM allows safe manufacturing with a standard ESD control

process.
