Watchdog timing period calculation formula: PWD = 0.991 * REXT+0.648 (REXT in kΩ and PWD in ms).

Table 3. Static Electrical Characteristics (continued)

All characteristics are for the analog chip only. Refer to the 68HC908EY16 data sheet for characteristics of the microcontroller

chip. Characteristics noted under conditions 9.0 V ≤ VSUP ≤ 16 V, -40°C ≤ TJ ≤ 125°C unless otherwise noted. Typical values

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