73S8023C  
Smart Card Interface  
Simplifying System Integration™  
DATA SHEET  
April 2009  
DESCRIPTION  
FEATURES  
The Teridian 73S8023C is a low-power, high efficiency,  
single smart card interface IC suitable for 3V and 5V  
cards. It provides full electrical compliance with ISO-  
7816-3 and EMV 4.0 (EMV2000) specifications.  
Card Interface:  
. Complies with ISO-7816-3, EMV 4.0  
. A DC-DC Converter provides 3V / 5V to the card  
from an external power supply input  
Hardware support for any type of synchronous cards  
(memory cards) is provided.  
. High-efficiency converter: > 80% @ VDD=3.3 V,  
VCC=5 V and ICC = 65 mA  
. Up to 100 mA supplied to the card  
Interfacing with the system controller is done through the  
control bus; composed of digital inputs to control the  
interface, and one interrupt output to inform the system  
controller of the card presence and faults. Data exchange  
with the card is managed from the system controller using  
the I/O line (and eventually the auxiliary I/O lines).  
. ISO-7816-3 Activation / Deactivation sequencer  
with emergency automated deactivation  
. Protection includes 2 voltage supervisors which  
detect voltage drops on card VCC and on VDD  
power supply  
. The VDD voltage supervisor threshold value can be  
externally adjusted  
A chip select input allows multiple 73S8023C ICs to share  
the same control bus. When chip select is set low, the  
host microcontroller inputs are latched and outputs are  
taken to a high impedance state.  
. True over-current detection (150 mA max.)  
. 2 card detection inputs, 1 for either possible switch  
configuration  
The card clock signal can be generated by an on-chip  
oscillator using an external crystal or by connecting an  
external clock signal.  
. Full support of synchronous cards  
System Controller Interface:  
. 3 Digital inputs control the card activation /  
deactivation, card reset and card voltage  
The 73S8023C device incorporates an ISO-7816-3  
activation/deactivation sequencer that controls the card  
signals. Emergency card deactivation is initiated upon  
card extraction or upon any fault generated by the  
protection circuitry.  
. 3 Digital inputs control the card clock (division rate  
and card clock source selection)  
. 1 Digital output, interrupt to the system controller,  
allows the system controller to monitor the card  
presence and faults  
. 1 Power down digital input (places the 73S8023C  
in a very low-power mode (card deactivated)  
The 73S8023C requires only a single 2.7 V to 3.6 V power  
supply, and features a high-efficiency embedded DC-DC  
converter. This architecture, plus a Power Down digital  
input that allow placing the IC in a very low-power mode  
making the 73S8023C particularly suitable for low-power  
applications (cell-phones, PDAs, payphones, hand-held  
POS terminals…).  
. 1 Chip select digital input for parallel operation of  
several 73S8023C ICs.  
. 1 External clock input (STROBE), used for  
synchronous operation  
. 1 Digital output clock, buffered version of signal on  
XTALIN  
ADVANTAGES  
Supports both synchronous and asynchronous smart  
cards  
. Crystal oscillator or host clock (XTALIN), up to  
27 MHz  
Replacement for TDA8002, with up to 600 mW in  
power savings (@ EMV ICCmax condition) !  
Power Supply: VDD 2.7 V to 3.6 V  
The inductor-based DC-DC converter provides higher  
current and efficiency  
6 kV ESD Protection on the card interface  
Ideal for battery-powered applications  
APPLICATIONS  
Suitable for high current cards and SAMs: (100 mA  
Point of Sales and Transaction Terminals  
Payphones  
max)  
Single 2.7 V to 3.6 V power supply allows removal  
Set-Top-Boxes, DVD / HDD Recorders  
of 5 V from the system  
Payment card interfaces in portable devices (PDAs,  
mobile phones…)  
Power down mode: 2 µA typical  
Package: Small Format (5x5mm) 32-QFN
