ST8034T, ST8034AT, ST8034P, ST8034C 16-pin smartcard interfaces Datasheet - production data 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 5 V or 3 V or 1.8 V (ST8034P) CC Automatic card activation and deactivation sequences initiated by the microcontroller SO16 3.9 x 9.9 mm Emergency deactivation sequences initiated by a card supply short-circuit, card take-off, falling V , V , or V or by the DD DDP DD(INTF) interface device overheating Voltage supply supervisors With a fixed threshold (V , V , and DD DDP V ) DD(INTF) Optionally with an external resistor divider to set the V threshold (PORADJ QFN16 3 x 3 mm DD(INTF) pin ST8034P and ST8034C) Multipurpose card status signal OFF Non-inverted card reset pin RST driven by the RSTIN input Features Thermal and short-circuit protection of all card Complete smartcard interface contacts ISO 7816 and EMV 4.3 payment systems Card presence detection contacts debounced compatible Enhanced card side ESD protection of 8 kV One protected half-duplex bidirectional Common SO16 3.9 x 9.9 mm body or a space- buffered I/O line to the smartcard saving QFN16 3 x 3 mm package 5 V or 3 V (or 1.8 V in case of ST8034P) Temperature range -25 to +85 C selectable smartcard supply voltage (V ). CC Ensures controlled V rise and fall times and CC provides smart overload detection with glitch Applications immunity. Smartcard readers for Optional chip select function allows the device Set-top boxes interface to be isolated from the host microcontroller signals - allows parallel Pay-TV combination of the card interface devices Identification (ST8034C) Banking Card clock generation by integrated crystal Tachographs oscillator or from external clock source October 2013 DocID024587 Rev 4 1/40 This is information on a product in full production. www.st.com 1Contents ST8034T, ST8034AT, ST8034P, ST8034C Contents 1 Description . 6 2 Block diagrams . 7 3 Pin description 10 4 Maximum ratings . 13 5 Electrical characteristics 14 Electrical characteristics over recommended operating conditions . 14 6 Functional description 22 6.1 Power supplies . 22 6.2 Voltage supervisor 22 6.2.1 Voltage supervisor ST8034T and ST8034AT . 22 6.2.2 Voltage supervisor with PORADJ function (ST8034P and ST8034C) 23 6.3 Clock circuits 25 6.3.1 ST8034T and ST8034AT clock possibilities 25 6.3.2 ST8034P and ST8034C clock 26 6.4 Input and output circuits 26 6.5 Shutdown mode 26 6.6 Activation sequence . 27 6.7 Deactivation sequence . 28 6.8 V generator . 29 CC 6.9 Fault detection . 29 6.10 Card supply voltage (V ) selection 31 CC 6.10.1 Automatic determining of card supply voltage (V ) - all versions CC except ST8034P 31 6.10.2 Card supply (V selection by tristate VCC SEL pin (ST8034P only) . 32 CC) 6.11 Chip select (ST8034C only) . 32 7 Package information 33 8 Tape and reel information 37 9 Revision history . 39 2/40 DocID024587 Rev 4
