External clock sources

Each i.MX RT1050 processor has two external input system clocks: a low frequency (RTC_XTALI) and

a high frequency (XTALI).

RT1050 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 RT1050 Hardware

Development Guide (IMXRT1050HDG).

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

to below 3.49 V.
