73S8004R

Low Cost Smart Card Interface

September 2003

DESCRIPTION

The TDK 73S8004R is a single smart card interface IC

that can be controlled by a dedicated control bus. The

TDK 73S8004R provides full electrical compliance with

ISO-7816-3 and EMV 4.0 (EMV2000) specifications.

FEATURES

•

Card Interface:

ꢁComplies with ISO-7816-3 and EMV 4.0

ꢁA LDO voltage regulator provides 3V / 5V to the

card from an external power supply input

ꢁProvides at least 65mA to the card

ꢁISO-7816-3 Activation / Deactivation sequencer

with emergency automated deactivation on card

removal or fault detected by the protection circuitry

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).

ꢁProtection includes 3 voltage supervisors that

detect voltage drops on V_CC(card), V_DD(digital),

and V_PC(regulator) power supplies

ꢁThe V_DDvoltage supervisor threshold value can be

The card clock signal can be generated by an on-chip

oscillator using an external crystal or connection to a clock

signal coming from the system controller.

externally adjusted

ꢁOver-current detection 150mA max.

ꢁCard clock stop high or low

ꢁ2 card detection inputs, 1 for each possible user

incorporates

ISO-7816-3

polarity

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.

ꢁAuxiliary I/O lines, for C4 / C8 contact signals

•

System Controller Interface:

ꢁ

3 Digital inputs control the card activation /

deactivation, card reset and card voltage

With its embedded LDO regulator, the TDK 73S8004R is a

cost-effective solution for any application where a 5V

(typically -5% +10%) power supply is available.

Hardware support for auxiliary I/O lines, C4 / C8 contacts,

is provided.

4 Digital inputs control the card clock (division

rate and card clock stop modes)

1 Digital output, interrupt to the system controller,

allows the system controller to monitor the card

presence and faults.

ꢁ

Crystal oscillator or host clock, up to 26MHz

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 V_DD

(digital power supply), a V_PC(regulator power supply), a

V_CC(card power supply) or an over-heating fault.

•

Regulator Power Supply:

4.75V to 5.5V (EMV 4.0)

ꢁ

•

Digital Interfacing: 2.7V to 5.5V

6kV ESD Protection on the card interface

Package: SO28

Digital circuitry is separately powered by a digital power

supply V_DD. The V_DDvoltage fault has a threshold voltage

that can be adjusted with an external resistor or resistor

network. It allows automated card deactivation at a

customized V_DDvoltage threshold value.
