USB Transceiver Characteristics
Notes:
5.
ICC measurement includes USB Transceiver current operating at Full Speed.
6.
ICCSUS1 measured with 12-MHz Clock Input and Internal PLL enabled. Suspend set –(USB transceiver and internal Clocking disabled).
7.
ICCSUS2 measured with external Clock and PLL disabled and Suspend set. For absolute minimum current consumption ensure that all inputs to the device are
at static logic level.
8.
All typical values are VDD = 3.3V and Tamb= 25°C.
9.
ZUSBX Impedance Values includes an external resistor of 33–42 Ohms ±1%.
