View Datasheet Manufacturer Site View Pricing & Stock

The ST8034T/ST8034AT/ST8034P/ST8034C devices are complete low-cost analog interfaces for asynchronous and synchronous smartcards operating at a supply voltage of 5 V or 3 V (or even 1.8 V in the case of ST8034P). The ST8034T/ST8034AT/ST8034P/ST8034C devices can be placed between the card and the microcontroller to provide all supply, protection, detection and control functions, with just a few external components.

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
