ST8034ATDT Smartcard Interfaces by STMicroelectronics
16-pin smartcard interfaces
| Status: | Active |
|---|---|
| Series: | ST8034AT |
| RoHS: | Compliant |
Features
| 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)) |
| Optionally with an external resistor divider to set the VDD(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 |
