USB Application Guide

Module can be used as a USB device. Module supports the USB suspend and resume mechanism
which can reduce power consumption. If there is no data transmission on the USB bus, Module will
enter suspend mode automatically and will be resumed by some events such as voice call, receiving
SMS, etc.

Figure 17: USB reference circuit

Because of the high bit rate on USB bus, more attention should be paid to the influence of the
junction capacitance of the ESD component on USB data lines. Typically, the capacitance should
be less than1pF. It is recommended to use an ESD protection component such as ESD9L5.0ST5G
provided by On Semiconductor (

www.onsemi.com

).

D3 is suggested to select the diode with anti-ESD and voltage surge function, or customer could
add a ZENER diode for surge clamping. The recommend diodes list please refer to table 7.
L is recommended (MURATA) DLW21SN371SQ2L.

Note

：

The USB_DM and USB_DP nets must be traced by 90Ohm+/-10% differential impedance.

3.5 USIM Interface

Module supports both 1.8V and 3.0V USIM Cards.
