1.
POR width is dependent on the 32 or 32.768 kHz crystal oscillator start-up time. Design margin should
allow for crystal tolerance, i.MX chip variations, temperature impact, and supply voltage influence.
Through the process of supplying crystals for use with CMOS oscillators, crystal manufacturers have
developed a working knowledge of start-up time of their crystals. Typically, start-up times range from
400 ms to 1.2 seconds for this type of crystal.
If an external stable clock source (already running) is used instead of a crystal, the width of POR should
be ignored in calculating timing for the start-up process.
