ST8034HN Datasheet PDF

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 VCC rise 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 Datasheet - production data
● Automatic activation and deactivation sequences initiated by the microcontroller
● Emergency deactivation sequences initiated by a card supply short-circuit,...
