The T=0 transmission protocol was first used in France during the initial development of smart cards, and it was also the first internationally standardized smart card protocol. It was generated in the early years of smart card technology, and it is thus designed for minimum memory usage and maximum simplicity.The SERCOM USART features an ISO/IEC 7816-compatible operating mode. This mode permits interfacing with smart cards and Security Access Modules (SAM) communicating through an ISO 7816 link. Both T=0 and T=1 protocols defined by the ISO 7816 specification are supported.
The ISO 7816 standard defines the necessary protocols to communicate with a smart card. Although the communication software is tested with TimeCOS, the basic communication protocol (ISO 7816, T = 0) implemented in this application note is common with all smart cards. 2012 Freescale Semiconductor, Inc. An APDU is an Application Protocol Data Unit, a TPDU a Transport Protocol Data Unit. If an APDU command response pair has been defined for T=0 and it has both command data and response data (case 4S) then a separate TPDU will be generated to send and receive data ( GET RESPONSE ).
T=0 is a byte based protocol while T=1 uses frames underneath. Most cards with T=0 don't support extended length. Note that to get extended length functionality that the javacardx.apdu.ExtendedLength tagging interface needs to be implemented. JCOP cards can be configured to use T=0/T=1/T=CL and others. This application note describes the fundamentals of the contact type smart cards, and how they are communi-cated using the PIC microcontroller. It also explains the T = 0 and T = 1 protocols, which are widely used in contact type smart card communications.Smart card can be interfaced with MCU using ISO7816 protocol, a standard for electronic identification cards with contacts. This section explains the MCU interface detail such as required I/O pins, USART
The T = 0 protocol is the predominant protocol in France and was the only protocol specified in ISO 7816 - 3. In 1992 ISO standardised the T = 1 protocol as amendment 1 to ISO 7816 - 3. Clearly the IC card and the interface device must operate with a common protocol.I am struggle to understand what protocol I have to use to communicate with the card T0 or T1?
