ST8034AT:16-pin smartcard interfaces

The ST8034T/ST8034AT/ST8034P/ST8034C devices are complete low-cost analog interfaces for asynchronous and synchronous smartcards operating at a supply voltage of 5 V or 3 V (or even 1.8 V in the case of ST8034P).

The ST8034T/ST8034AT/ST8034P/ST8034C devices can be placed between the card and the microcontroller to provide all supply, protection, detection and control functions, with just a few external components.

Key Features

  • Complete smartcard interface
  • ISO 7816 and EMV™ 4.3 payment systems compatible
  • One protected half-duplex bidirectional buffered I/O line to the smartcard
  • 5 V or 3 V (or 1.8 V in case of ST8034P) selectable smartcard supply voltage (VCC ). Ensures controlled VCC rise and fall times and provides smart overload detection with glitch immunity.
  • Optional chip select function allows the device interface to be isolated from the host microcontroller signals - allows parallel combination of the card interface devices (ST8034C)
  • Card clock generation by integrated crystal oscillator or from external clock source
  • Card clock frequency up to 20 MHz, programmable by CLKDIV pin, with synchronous frequency changes
  • Optional VCC_SEL input for pin-controlled selection of VCC ; 5 V or 3 V or 1.8 V (ST8034P)
  • Automatic card activation and deactivation sequences initiated by the microcontroller
  • Emergency deactivation sequences initiated by a card supply short-circuit, card take-off, falling VDD , VDDP , or VDD(INTF) or by the interface device overheating
  • Voltage supply supervisors
    • With a fixed threshold (VDD , VDDP , and VDD(INTF) )
    • Optionally with an external resistor divider to set the VDD(INTF) threshold (PORADJ pin; ST8034P and ST8034C)
  • Multipurpose card status signalOFF
  • Non-inverted card reset pin RST driven by the RSTIN input
  • Thermal and short-circuit protection of all card contacts
  • Card presence detection contacts debounced
  • Enhanced card side ESD protection of 8 kV
  • Common SO16 3.9 x 9.9 mm body or a space-saving QFN16 3 x 3 mm package
  • Temperature range -25 to +85 °C
