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

compatible
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
immunity.
Applications
Smartcard readers for
Set-top boxes
Pay-TV
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)
