STOTG04 demonstration board hardware

Demonstration board layout

1.1

STOTG04 power requirements

The recommended supply voltages of the transceiver are:

●

VIF = 1.6 V to 3.6 V (VIF = 1.8 V, typ)

●

VBAT = 2.7 V to 5.5 V (VBAT = 3.3 V, typ).

The demonstration board was designed for these same voltage ranges. However, the board

does not contain any voltage regulators, so if only one common supply voltage is used, the

following range is recommended:

VCOMMON = 2.7 V to 3.6 V

Note:

Jumper J7 connecting the VBAT and VIF power supply pins has to be shorted (see Table 1).

1.2

Connecting to a PC

The STOTG04 demonstration board must be connected to the PC serial port via a

non-crossed serial cable. The PC serial port can be selected in the USB OTG

demonstration board software (see Chapter 2).
