Junction temperature –40 – +100 °C The temperature rise from
ambient to junction is package
specific. See Thermal
Impedance on page 44. The
user must limit the power
consumption to comply with this
requirement.

Notes
14. Errata: When the device is operating at 4.75 V to 5.25 V and the 3.3 V regulator is enabled, a short low pulse may be created on the DP signal line during device
wake-up. The 15-20 μs low pulse of the DP line may be interpreted by the host computer as a deattach or the beginning of a wake-up. More details in “Errata” on page 59.
15. Standby current includes all functions (POR, LVD, WDT, Sleep Time) needed for reliable system operation. This should be compared with devices that have similar
functions enabled.
