Caratteristiche principali

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 (V_CC). Ensures controlled V_CCrise 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 V_CC; 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 V_DD, V_DDP, or V_DD(INTF)or by the interface device overheating
Voltage supply supervisors
- With a fixed threshold (V_DD, V_DDP, and V_DD(INTF))
- Optionally with an external resistor divider to set the V_DD(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
