May I exchange the in/out of EMIF03-SIM02M8?

[diverger]

Hi,

May I exchange the in/exit of the EMIF03? As the pin name indicate there are in pins and exit pins. But from the internal diagram, the ins and outs are exchangeable.

Thanks.

Hi,

Unfortunately, IN and OUT cannot be exchanged, as external pins withstand +/-8kV ESD contact discharge, +/-15kV ESD air discharge, whereas internal pins withstand +/-2kV ESD contact and air discharge. So, external pins are compliant with IEC 61000-4-2 level 4, which is not the case for internal pins. External pins need to be connected to SIM socket, internal pins to SIM card reader IC. However, RST and DATA can be exchanged, as schematic is the same.

Best regards.
