3.5.2 Application Guide
It is recommended to use an ESD protection component such as ST (www.st.com ) ESDA6V1W5 or ON
SEMI (www.onsemi.com ) SMF05C. Note that the SIM peripheral circuit should be close to the SIM card
socket. The reference circuit of the 6-pin SIM card holder is illustrated in the following figure.
Pin name Pin Description
USIM_CLK 19 USIM Card Clock
USIM_RST 18 USIM Card Reset
USIM_DATA 17
USIM Card data I/O, which has been pulled up with a 22kR resistor to
USIM_VDD in module. Do not pull up or pull down in users’
application circuit.
USIM_VDD 20
USIM Card Power output depends automatically on USIM mode，one
is 3.0V±10%, another is 1.8V±10%. Current is less than 50mA.
