73S8010C
Smart Card Interface
DATA SHEET
April 2009
DESCRIPTION
The Teridian 73S8010C is a single smart card
interface IC. It provides full electrical compliance
with ISO-7816-3 and EMV 4.0 specifications.
Interfacing with the host is done through the two-wire
I2C bus. Data exchange with the card is managed
from the system controller using the I/O line (and
eventually the auxiliary I/O lines).
An on-chip oscillator using an external crystal, or
connection to a clock signal coming from the
system controller can generate the card clock
signal.
The 73S8010C IC 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 DC-DC converter.
With its high-efficiency DC-DC converter, the
Teridian 73S8010C is a cost-effective solution for
any smart card reader application to be powered
from a single 2.7 V to 3.6 V power supply.
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 VDD (digital
power supply), a VCC (card power supply), a card
over-current, or an over-heating fault.
ADVANTAGES
Single smart card interface
The inductor-based DC-DC converter provides
higher current and efficiency than the usual
charge-pump capacitor-based converters
Ideal for battery-powered applications
Suitable for high current cards and
SAMs: (100 mA max)
Power down mode: 2 A typical
Small Format (5x5mm) 32-QFN package option
FEATURES
Card Interface:
Complies with ISO-7816-3 and EMV 4.0
A DC-DC Converter provides 3V / 5V to the
card from an external power supply input
High-efficiency converter: > 80% @ VDD= 3.3 V,
VCC = 5 V and ICC = 65 mA
Up to 100 mA supplied to the card
ISO-7816-3 Activation / Deactivation sequencer
with emergency automated deactivation on
card removal or fault detected by the protection
circuitry
Protection include 2 voltage supervisors that
detect voltage drops on card VCC and VDD
power supplies
The VDD voltage supervisor threshold value
can be externally adjusted
True over-current detection (150 mA max.)
1 card detection input
Auxiliary I/O lines, for C4 / C8 contact signals
Host Interface:
Fast mode, 400 kbps I2C slave bus
8 possible devices in parallel
One control register and one status register
Interrupt output to the host for fault
detection
Crystal oscillator or host clock, up to 27 MHz
Power Supply:
VDD: 2.7 V to 3.6 V
6 kV ESD Protection on the card interface
Package: SO28 or 32QFN
APPLICATIONS
Set-Top-Boxes, DVD / HDD Recorders:
Conditional Access and Pay-per-View slots
Point of Sales and Transaction Terminals
EMV slots in cell phones and PDAs

Description
Interrupt output (negative assertion): Interrupt output signal to the
processor. A 20 kpull up to VDD is provided internally.
Power Down control input: Active High. When Power Down (PD) mode is
activated, all internal analog functions are disabled to place the 73S8010C
in its lowest power consumption mode. Must be tied to ground when the
power down function is not used.
Serial device address bits: Digital inputs for address selection that allow
the connection of up to 8 devices in parallel. Address selections as follows:
