Alternatively, if 3.0 to 3.6 V power is supplied to the VDD pin, the CP2104 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 9.
The USB max power and power attributes descriptor must match the device power usage and configuration. See
application note “AN144: CP21xx Device Customization Guide” for information on how to customize USB
descriptors for the CP2104.

Note 1 : 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 2 : An external pull-up is not required, but can be added for noise immunity.
Note 3 : VIO can be connected directly to VDD or to a supply as low as 1.8 V to set the I/O interface
voltage.
Note 4 : If configuration ROM is to be programmed via USB, a 4.7
F capacitor must be added
between VPP and ground. During a programming operation, the pin should not be
connected to other circuitry, and VDD must be at least 3.3 V.
