Figure 9. Peripheral-Side (Low-Speed) Regulator Bypass Mode

This mode is applicable when there is a 3.3-V supply already available on the board. The VBUS pin of the USB

connector, if left unused at the peripheral side, should be terminated with a 0.1-

µF capacitor. While operating at

low speed, the 1.5-k

Ω resistor must to be connected between the D– line and VPU(3.3) or an external 3.3-V

supply. When the VCC(5.0) and the Vreg(3.3) are connected together, the device operates at regulator bypass mode.

This enables power savings since the regulator is turned off.
