The SIM is an integral part of the GSM system - it is fully specificed in the GSM specs. Do you mean the chip used in a SIM card is fully specified at interface level? Is there enough information that one can directly interface the SIM to 8051? Can you point to the particular document? Andy Neil said:
GSM also defines AT commands for accessing the SIM through a GSM "engine" (phone, modem, whatever):
07.07 - AT command set for GSM Mobile Equipment Agree, all GSM engines provide access to SIM through AT commands. But OP intends to interface a SIM directly to 8051, not through ME or GSM module. |
