Smart Card Interface

The interface between the ACR38 and the inserted smart card follows the specifications of

ISO7816-3

with

certain restrictions or enhancements to increase the practical functionality of the ACR38.

Smart Card Power Supply VCC (C1)

The current consumption of the inserted card must not be higher than 50 mA.

Programming Voltage VPP (C6)

According to ISO 7816-3, the smart card contact C6 (VPP) supplies the programming voltage to the smart

card. Since all common smart cards in the market are EEPROM based and do not require the provision of

an external programming voltage, the contact C6 (VPP) has been implemented as a normal control signal in

the ACR38. The electrical specifications of this contact are identical to those of the signal RST (at contact

C2).

Card Type Selection

The controlling PC always has to select the card type through the proper command sent to the ACR38 prior

to activating the inserted card. This includes both the memory cards and MCU-based cards.

For MCU-based cards, the reader allows to select the preferred protocol, T=0 or T=1. However, this

selection is only accepted and carried out by the reader through the PPS when the card inserted in the

reader supports both protocol types. Whenever an MCU-based card supports only one protocol type, T=0 or

T=1, the reader automatically uses that protocol type, regardless of the protocol type selected by the

application.

Interface for Microcontroller-based Cards

For microcontroller-based smart cards only the contacts C1 (VCC), C2 (RST), C3 (CLK), C5 (GND) and C7

(I/O) are used. A frequency of 4 MHz is applied to the CLK signal (C3).

Card Tearing Protection

The ACR38 provides a mechanism to protect the inserted card when it is suddenly withdrawn while it is

powered up. The power supply to the card and the signal lines between the ACR38 and the card are

immediately deactivated when the card is being removed. As a general rule, however, to avoid any electrical

damage,

a card should only be removed from the reader while it is powered down.

NOTE

- The ACR38 does never by itself switch on the power supply to the inserted card. This must explicitly be done by the

controlling computer through the proper command sent to the reader.
