PRELIMINARYNXP Semiconductors 21
The typical values shown in Table 7 are required for use with NXP board support packages (BSPs) to
ensure precise time keeping and USB operations.
4.1.5 Maximum Supply Currents
2
The required frequency stability of this clock source is application dependent. For recommendations, see the Hardware
Development Guide.
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.
