Series: | ST8034C |
RoHS: | Compliant |
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 VCCrise 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) |
With a fixed threshold (VDD, VDDP, and VDD(INTF)) |
