RT1060X Product Lifetime Usage

Estimates for information on

product lifetime (power-on years)

for this processor.

1. Applying the maximum voltage results in maximum power consumption and heat generation. NXP recommends a voltage set

point = (Vmin + the supply tolerance). This result in an optimized power/speed ratio.

2. Applying the maximum voltage results in shorten lifetime. 3.6 V usage limited to < 1% of the use profile. Reset of profile limited

to below 3.49 V.

3. In setting VDD_SNVS_IN voltage with regards to Charging Currents and RTC, refer to the

i.MX RT1060 Hardware

Development Guide (IMXRT1060HDG).

4.1.4 External clock sources

Each i.MX RT1060X processor has two external input system clocks: a low frequency (RTC_XTALI) and a high frequency (XTALI).

The RTC_XTALI is used for low-frequency functions. It supplies the clock for wake-up circuit, power-down real time clock

operation, and slow system and watch-dog counters. The clock input can be connected to either external oscillator or a crystal

using internal oscillator amplifier. Additionally, there is an internal ring oscillator, which can be used instead of the RTC_XTALI if

accuracy is not important.

The system clock input XTALI is used to generate the main system clock. It supplies the PLLs and other peripherals. The system

clock input can be connected to either external oscillator or a crystal using internal oscillator amplifier.

Table 10 shows the interface frequency requirements.

1. External oscillator or a crystal with internal oscillator amplifier.

2. The required frequency stability of this clock source is application dependent.

3. Recommended nominal frequency 32.768 kHz.

4. External oscillator or a fundamental frequency crystal with internal oscillator amplifier.

The typical values shown in Table 10 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:
