Alternatively, if 3.0 to 3.6 V power is supplied to the V
device with the voltage regulator bypassed. For this configuration, tie the REGIN input to V
regulator. A typical connection diagram showing the device in a self-powered application with the regulator
bypassed is shown in Figure 12.
The USB max power and power attributes descriptor must match the device power usage and configuration. See
application note “AN144: CP21xx Customization Guide” for information on how to customize USB descriptors for
the CP2110.
Connector
Note 1 : VIO can be connected directly to VDD or to a supply as low as 1.8 V to set the I/O interface
Note 2 : Avalanche transient voltage suppression diodes compatible with Full-speed USB should be
Note 3 : An external pull-up is not required, but can be added for noise immunity.
Note 4 : If programming the configuration ROM via USB, add a 4.7 F capacitor between VPP
