Key Advantages
Traditional step-up converter is
replaced by a LDO regulator:
-
Better noise performance
(typical factor 10:1 with existing
converter based ICs)
- Highest card current interface in the
market: With 90mA for the ICC, it is
suitable for high-performance smart
cards and Secure Access Modules
- More cost-effective
True card over-current detection
Firmware compatible with industry-
standard TDA8020
Requires fewer external components
than typical ICC interface ICs
Up to 8 different 73S8010Rs can be
controlled in parallel trhough the I
2
C
bus (8 different addresses)
32MLF (5x5x.08mm) package option:
The smallest card interface IC of the
industry!
Low-Cost Smart Card Interface IC
The 73S8010R is an ISO-7816-3 electrical smart card interface IC, controllable by an
I
2
C bus. This makes it particularly suitable for applications that require several card
interfaces, such as multiple SAM (Secure Access Modules) configurations in POS and
payment terminals. The 73S8010R complies with the electrical requirements of ISO-
7816-3 and EMV 4.0 (EMV2000). It is available either in a standard SO28 package, or
in a 32-pin MLF package (5mmx5mmx0.8mm), making it the smallest solution available
today in the market. It can be used in any micro-controller-based design to implement
a generic smart card reader (terminal).
A significant advantage of the 73S8010R over existing IC solutions is the use of a Low
Drop-Out (LDO) voltage regulator to generate the card power supply (V
CC
) from a nom-
inal power supply source (V
PC
) of 5V. Digital circuitry is separately powered by a digi-
tal power supply (V
DD
) typically 3.3V, which is independent from the 5V supply of the
LDO regulator. The LDO exhibits improved noise performance when compared to typ-
ical step-up converter based ICs, which generate a lot of undesired noise and ripple
causing problems when trying to comply with applicable standards. The LDO architec-
ture also allows the 73S8010R to be the highest card current capable smart card inter-
face IC available today in the market, with up to 90mA minimum provided to the card.
Finally, the LDO regulator IC solution a with fewer external components make the
73S8010R a more cost effective solution for high-volume smart card readers in con-
sumer electronics applications such as set-top-boxes, digital TVs, or personal video
recorders.
The 73S8010R includes an ISO-7816 sequencer that controls the card activation/deac-
tivation. The card itself is also better protected, compared with existing ICs, since the
emergency card deactivation is initiated upon 5 possible hardware faults. These faults
are card extraction, card over-current, V
DD
fault, V
PC
fault (LDO regulator power sup-
ply), V
CC
fault (card power supply, output of the LDO regulator) or a die over-heating
fault.
The card over-current is a true current detection circuit, as opposed to the traditional
V
CC
voltage drop detector that is implemented in most of the available ICs in the mar-
ket. It guarantees a much cleaner card deactivation upon current fault.
The V
DD
fault detection has a threshold voltage that can be adjusted with an external
resistor or resistor network, allowing automated card deactivation at a customized V
DD
voltage threshold. This allows, for instance, customizing the automated card deactiva-
tion to match the operating voltage range of the host microcontroller.
The 73S8010R is the ideal solution for integration of a smart card reader in payment
systems, identification and conditional access terminals, where performance, small size
and low-cost are required.
