USB PLL is susceptible to power supply ripple. The maximum allowable supply ripple is 1% for 1 Hz to 5 kHz; 1.5% for 5 kHz to 10 MHz; 3%
for 10 MHz to 100 MHz, and less than 5% for 100 MHz or greater.
The I
2
C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered down.
Due to the fact that different voltage devices can be connected to the I
2
C bus, the level of logic 0 (low) and logic 1 (high) are not fixed and
depends on the associated V
DD
.
§
USB I/O pins DP and DN can tolerate a short circuit at D+ and D to 0 V or 5 V, as long as the recommended series resistors (see Figure 542)
are connected between the D+ and DP (package), and the D and DN (package). Do not apply a short circuit to the USB I/O pins DP and DN
in absence of the series resistors.
