ST8034T Datasheet, PDF (1/39 Pages) STMicroelectronics – 16-pin smartcard interfaces

ST8034T, ST8034AT, ST8034P,
ST8034C
16-pin smartcard interfaces
SO16 3.9 x 9.9 mm
QFN16 3 x 3 mm
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 (V_CC).
Ensures controlled V_CC 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
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_CC; 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 V_DD, V_DDP, or V_DD(INTF) or by the
interface device overheating
 Voltage supply supervisors
– With a fixed threshold (V_DD, V_DDP, and
V_DD(INTF))
– Optionally with an external resistor divider
to set the V_DD(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
