Functional specification
8.1 Hardware interface
8.1.1 Contact interface
The pad assignment and the electrical characteristics are fully compliant with
ISO/IEC 7816 (part 2 and part 3). The MIFARE SAM AV2 operates with Class A and
Class B interface devices. An internal charge pump provides the EEPROM programming
voltage. Note that pad C6 is not a programming voltage input but is an output line for the
clock signal for I2C communication to the RC222 reader chip. Pad C8 is used as data line
to the reader chip. These two pads for connection to the RC222 are the only ones
deviating from the ISO standard pin assignment.
8.1.2 External clock frequency and bit rates
The basic operation frequency of the MIFARE SAM AV2 is 3.5712 MHz. With this
frequency the following standard bit rates can be reached using ISO/IEC 7816
transmission factors F and D.
The MIFARE SAM AV2 supports significantly higher transmission speeds.
