3.5.1 SIM Application Guide
It is recommended to use an ESD protection component such as ESDA6V1W5 produced by ST
(www.st.com ) or SMF15C produced by ON SEMI (www.onsemi.com ). Note that the SIM
peripheral circuit should be close to the SIM card socket. The following figure shows the 6-pin
SIM card holder reference circuit.
