Hi all,

I have a few questions about Vusb_5(4.5 to 5.5V) and VBUS description(4.35 to 5.5V).

[Q1]

In Fig.1 below, Vusb_5 spec of VBUS pin is 4.5V(Min) to 5.5V(max).

In Fig.2 below, It is described as "ideally be 5V(4.35 to 5.5V is range)".

If 4.35V is input to the VBUS pin, will PSoC4200L work properly?

[Q2]

In Fig.2 below, It is described as "ideally be 5V(4.35 to 5.5V is range)".

In Fig.3 below, It is described as "5-V range(4.35 to 5.25V)".

Is the max value of the 5V range 5.5V or 5.25V?

Hello Yaku,

The specifications given in table 45 of the datasheet are specific to the USB Block of the PSoC device.

Regarding [1]  We recommend you to use input between 4.5V and 5.5V since these specifications are specific to the PSoC device.

The range 4.35 V to 5.5 V is what the USB spec mentions.

The same applies to the [2] point, the maximum value of the 5V range s 5.5 V.
