ELECTRICAL CHARACTERISTICS
DYNAMIC ELECTRICAL CHARACTERISTICS
Table 5. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 4.5 V ≤ VDD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 27 V, -40°C ≤ TA ≤ 125°C, unless otherwise noted.
Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.

Notes
23. Time necessary for the CSNS to be within ±5% of the targeted value.
24. Watchdog timeout delay measured from the rising edge of WAKE to 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.
25. RST low duration measured with outputs enabled and going to OFF or disabled condition.
