DATA SHEET
January 2008
DESCRIPTION
The TERIDIAN 73S8010R is a single smart card interface
IC. The TERIDIAN 73S8010R has been designed to
provide full electrical compliance with ISO-7816-3 and
EMV 4.0 (EMV2000) specifications.
ADVANTAGES
•
•
•
Single smart card interface
IC firmware compatible with TDA8020
Traditional step-up converter is replaced by a
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.
LDO regulator:
ꢀGreatly reduced power dissipation
ꢀFewer external components are required
ꢀBetter noise performance
The card clock signal can be generated by an on-chip
oscillator using an external crystal, or by connection to a
clock signal.
ꢀHigh current capability (90mA supplied to the card)
•
•
Small format (5x5x0.8mm) QFN32 package option
True card over-current detection
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 (3V or 5V), 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

Hardware support for auxiliary I/O lines, C4 / C8 contacts,
is provided.
ꢁProtection includes 3 voltage supervisors that

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

ꢁ1 card detection input
The card over-current circuitry is a true current detection
function, as opposed to VCC voltage drop detection, as
usually implemented in ICC interface ICs.
ꢁAuxiliary I/O lines, for C4 / C8 contact signals
ꢁCLK signal up to 20MHz
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.
