12. Electrical Characteristics: General (Continued)
This device is manufactured with an industrial (not automotive) grade process and process controls. Although this device may
meet certain automotive grade criteria in performance, Atmel can not recommend that this device be used in any automotive
application.
All parameters refer to GND and are valid for T
and V
about current consumption, timing and digital pin properties can be found in the specific sections of the “Electrical Characteristics”.
