NXP Semiconductors

The typical values shown in Table 10 are required for use with NXP board support packages (BSPs) to

ensure precise time keeping and USB operations.

4.1.5

Maximum Supply Currents

NOTE

Some of the numbers shown in this table are based on the companion

regulator limits and not actual use cases. Work is in progress to provide use

case–based numbers in future data sheet releases.

1 External oscillator or a crystal with internal oscillator amplifier.

2 The required frequency stability of this clock source is application dependent. For recommendations, see the hardware

development guide for this device.

3 Recommended nominal frequency 32.768 kHz.

4 Fundamental frequency crystal with internal oscillator amplifier.

5 If using an external clock instead of the internal clock source, an HCSL-compatible clock is required.
