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
