12.11 COMMUNICATION INTERFACE CHARACTERISTICS
12.11.1 USB - Universal Bus Interface
(Operating conditions T
A = 0 to +70°C, V
DD = 4.0 to 5.25V unless otherwise specified)
Notes
1. RL is the load connected on the USB drivers.
2. All the voltages are measured from the local ground potential.
3. Not tested in production, guaranteed by design.
4. To improve EMC performance (noise immunity), it is recommended to connect a 100nF capacitor to the
USBVCC pin.

Note 1: Measured from 10% to 90% of the data signal. For more detailed informations, please refer to Chapter 7 (Elec-
trical) of the USB specification (version 1.1).
