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
