FEATURES

DESCRIPTION

The Teridian 73S8009CN is the world’s first

single-chip smart card electrical interface circuit that

supports all types of smart cards: 5V, 3V and 1.8V,

including traditional ISO-7816-3 asynchronous and

synchronous type 1 and type 2, as well as USB,

ISO-7816-12 cards.

The 73S8009CN is ideally suited for applications

such as desktop computers, laptops and general

purpose smart card readers that require low power

operation from a single 2.7V to 6.5V power supply

voltage source. A power down mode (“OFF” mode)

is available and exhibits a 10nA typical current

consumption.

The circuit provides control, conversion and regulation

of power for the smart card. In addition, the circuit

provides a 3.3V-regulated voltage that is used as an

internal digital supply voltage to the host interface. It is

also made available to supply power to some external

circuitry (a host controller for instance).

For asynchronous and synchronous smart card

operation, the signals for RST, CLK, I/O and auxiliary

signals AUX1 and AUX2 are directly controlled from

the host processor and are level-shifted by the circuit

to the selected V

value. For more design flexibility,

the host processor is responsible for handling the

signal timing for smart card activation and de-

activation under normal conditions.

The power management circuitry allows operation

from a single power supply source V

(2.7V to 6.5V).

is converted using an inductive, step-up power

converter to the intermediate voltage, V

. V

is used

by linear voltage regulators and switches internal to

the IC to create the voltages V

and as required,

. V

is used by the 73S8009CN and is also

made available for the companion host processor

circuit or for other external circuits.

The 73S8009CN features an ON/OFF pin suitable to

connect to a “push-on/push-off” main system switch.

When the 73S8009CN is “OFF,” the typical current

drawn from VPC is 10nA. For applications that do

not implement any ON/OFF system switch, the

ON/OFF input pin can be driven from a digital output

of the host processor.
