Figure 19: USIM interface reference circuit
Note: USIM_DATA has been pulled up with a 100KΩ resistor to USIM_VDD in module. A
100nF capacitor on USIM_VDD is used to reduce interference. For more details of AT
commands about USIM, please refer to document [1].USIM_CLK is very important signal, the
rise time and fall time of USIM_CLK should be less than 40ns, otherwise the USIM card might
not be initialized correctly.
