1 / 39 page This is information on a product in full production. October 2013 DocID024587 Rev 4 1/40 1 ST8034T, ST8034AT, ST8034P, ST8034C 16-pin smartcard interfaces Datasheet - production data 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 VCC rise 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) Multipurpose card status signal OFF 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 Applications Smartcard readers for Set-top boxes Pay-TV Identification Banking Tachographs QFN16 3 x 3 mm SO16 3.9 x 9.9 mm www.st.com |
