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 VCC 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 VPC (2.7V to 6.5V).
VPC is converted using an inductive, step-up power
converter to the intermediate voltage, VP. VP is used
by linear voltage regulators and switches internal to
the IC to create the voltages VDD and as required,
VCC. VDD 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.
