产品概述

描述

The ST8034HN and ST8034HC devices are complete low-cost analog interfaces for asynchronous and synchronous smartcards operating at a supply voltage of 5 V, 3 V or 1.8 V. The ST8034HN and ST8034HC 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.

  • 所有功能

    • Complete smartcard interface
    • ISO 7816, NDS and EMV 4.3 payment systems compatible
    • Three protected half-duplex bidirectional buffered I/O lines to the smartcard
    • 5 V, 3 V or 1.8 V supply voltage for the smartcard (VCC), pin-selectable. Ensures controlled VCCrise and fall times and provides smart overload detection with glitch immunity.
    • Very low power consumption in deep shutdown mode
    • Chip select function allows the device interface to be isolated from the microcontroller signals - allows parallel combination of the card interface devices (ST8034HC)
    • Card clock generation by integrated crystal oscillator or from external clock source
    • Card clock frequency up to 20 MHz, programmable by CLKDIV1 and CLKDIV2 pins (ST8034HN) or by CLKDIV pin (ST8034HC), with synchronous frequency changes
    • Automatic 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)
      • with an external resistor divider to set the VDD(INTF)threshold (PORADJ pin)
    • 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
    • Space saving QFN24 4 x 4 x 0.8 mm package
    • Temperature range -25 to +85 °C
