Note 1: Operation guaranteed at -40°C and +85°C but not tested.
Note 2: IDD_IC measures the amount of current used by the DS8113 to provide the smart card current minus the load.
Note 3: Stop mode is enabled by setting CMDVCC, 5V/3V, and 1_8V to a logic-high.
Note 4: Parameters are guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the maximum
rise and fall time is 10ns.
Note 5: Parameter is guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the minimum
slew rate is 0.05V/µs and the maximum slew rate is 0.5V/µs.
