NXP Semiconductors

The typical values shown in Table 11 are required for use with NXP SDK to ensure precise time keeping

and USB operation. For RTC_XTALI operation, two clock sources are available.

•

On-chip 40 kHz ring oscillator—this clock source has the following characteristics:

— Approximately 25 µA more Idd than crystal oscillator

— Approximately ±50% tolerance

— No external component required

— Starts up quicker than 32 kHz crystal oscillator

•

External crystal oscillator with on-chip support circuit:

— At power up, ring oscillator is utilized. After crystal oscillator is stable, the clock circuit

switches over to the crystal oscillator automatically.

— Higher accuracy than ring oscillator

— If no external crystal is present, then the ring oscillator is utilized

The decision of choosing a clock source should be taken based on real-time clock use and precision

time-out.

Maximum supply currents

The data shown in Table 12 represent a use case designed specifically to show the maximum current

consumption possible. All cores are running at the defined maximum frequency and are limited to L1

cache accesses only to ensure no pipeline stalls. Although a valid condition, it would have a very limited

practical use case, if at all, and be limited to an extremely low duty cycle unless the intention were to

specifically show the worst case power consumption.

See the i.MX RT1064 Power Consumption Measurement Application Note for more details on typical

power consumption under various use case definitions.
