VSNVS specifications

Table 95. VSNVS electrical characteristics

All parameters are specified at Consumer TA = -40 to 85 °C and Extended Industrial TA = -40 to 105 °C, VIN = 3.6 V, VSNVS = 3.0 V,

ISNVS = 5.0 μA, typical external component values, unless otherwise noted. Typical values are characterized at VIN = 3.6 V, VSNVS =

3.0 V, ISNVS = 5.0 μA, and 25 °C, unless otherwise noted.

Notes

68.

During crossover from VIN to LICELL, the VSNVS output voltage may drop to 2.7 V before going to the LICELL voltage. Though this is outside the

specified DC voltage level for the VDD_SNVS_IN pin of the i.MX 6, this momentary drop does not cause any malfunction. The i.MX 6’s RTC

continues to operate through the transition, and as a worst case it may switch to the internal RC oscillator for a few clock cycles before switching

back to the external crystal oscillator.
