ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
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 ≤ V_SUP ≤ 16 V, - 40 °C ≤ T_J ≤ 125 °C, unless otherwise noted. Typical values
noted reflect the approximate parameter mean at T_A = 25°C under nominal conditions, unless otherwise noted.

Notes
14. Watchdog timing period calculation formula: P_WD = 0.991 _* R_EXT+0.648 (R_EXT in kΩ and P_WD in ms).
15. This parameter is guaranteed by process monitoring but it is not production tested
16. When over-temperature occurs, switch is turned off and latched off. Flag is set in SPI.
