9 Electrical Characteristics and Requirements
The following electrical characteristics are preliminary and are subject to change. Electrical characteristics refer to
the behavior of the device under specified conditions. Electrical requirements refer to conditions imposed on the
user for proper operation of the device. The parameters below are valid for the following conditions:
VDD = 5 V ± 10% (See Section 8.3 on page 47 for exceptions.)
