Low Cost Smart Card Interface
DATA SHEET
August 2009
DESCRIPTION
The Teridian 73S8010R is a single smart card
interface IC that provides full electrical compliance
with ISO-7816-3 and EMV 4.0 (EMV2000)
specifications.
Interfacing with the host is done through the two-wire
I2C bus and one interrupt output to inform the
system controller of the card presence and faults.
The card clock signal can be generated by an
on-chip oscillator using an external crystal, or by
connection to a clock signal.
The Teridian 73S8010R incorporates an ISO-7816-3
activation/deactivation sequencer that controls the
card signals. Level-shifters drive the card signals with
the selected card voltage (3 V or 5 V), coming from an
internal Low Drop-Out (LDO) voltage regulator. This
LDO regulator is powered by a dedicated power
supply input, VPC. Digital circuitry is separately
powered by a digital power supply, VDD.
With its embedded LDO regulator, the Teridian
73S8010R is a cost-effective solution for any
application where a 5 V (typically -5% +10%) power
supply is available. Hardware support for auxiliary
I/O lines, C4 / C8 contacts is provided.
Emergency card deactivation is initiated upon
card extraction or upon any fault generated by
the protection circuitry. The fault can be a card
over-current, a VDD (digital power supply), a VPC
(regulator power supply), a VCC (card power supply)
or an over-heating fault.
The card over-current circuitry is a true current detect
function, as opposed to VCC voltage drop detection, as
usually implemented in ICC interface ICs.
The VDD voltage fault has a threshold voltage that
can be adjusted with an external resistor or resistor
network. It allows automated card deactivation at a
customized VDD voltage threshold value. It can be
used, for instance, to match the system controller
operating voltage range.
