... POWER SUPPLY AND VOLTAGE SUPERVISON The TDK 73S8024RN smart card interface IC incorporates a LDO voltage regulator. The voltage output is controlled by the digital input 5V/#V. This regulator is able to provide either card voltage from the power supply applied on the VPC pin. Digital circuitry is powered by the power supply applied on the VDD pin. V interface with the system controller ...

... ON-CHIP OSCILLATOR AND CARD CLOCK The TDK 73S8024RN device has an on-chip oscillator that can generate the smart card clock using an external crystal (connected between the pins XTALIN and XTALOUT) to set the oscillator frequency. When the clock signal is available from another source, it can be connected to the pin XTALIN, and the pin XTALOUT should be left unconnected ...

... ACTIVATION SEQUENCE The TDK 73S8024RN smart card interface IC has an internal 10ms delay at power on reset or on the application of V > activation is allowed at this time. The CMDVCC (edge triggered) must then be set low to DD DDF activate the card. In order to initiate activation, the card must be present; there can be no over-temperature fault fault ...
