Rev. 1.1

Alternatively, if 3.0 to 3.6 V power is supplied to the VDD pin, the CP2110 can function as a USB self-powered
device with the voltage regulator bypassed. For this configuration, tie the REGIN input to VDD to bypass the voltage
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.

Note 4
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
voltage. VIO is internally connected to VDD on -GM1 packages.
Note 2 : Avalanche transient voltage suppression diodes compatible with Full-speed USB should be
added at the connector for ESD protection. Use Littelfuse p/n SP0503BAHT or equivalent.
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
and ground. During a programming operation, do not connect the VPP pin to other
circuitry, and ensure that VDD is at least 3.3 V.
