Features

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)
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
