Notes

23.

Time necessary for the CSNS to be with ±5% of the targeted value.

24.

Watchdog timeout delay measured from the rising edge of WAKE or RST from a sleep state condition, to output turn-ON with the output

driven OFF and FSI floating. The values shown are for WDR setting of [00]. The accuracy of tWDTO is consistent for all configured

watchdog timeouts.

Characteristics noted under conditions 4.5 V

≤ V

DD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 27 V, -40°C ≤ TJ ≤ 150°C unless otherwise noted.

Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
