3.0. Smart Card Support
3.1. MCU Cards
The ACR33U-A1 is a PC/SC compliant smart card reader that supports ISO 7816 Class A (5 V) smart
card. It also works with MCU cards following either the T=0 and T=1 protocol.
The card ATR indicates the specific operation mode (TA2 present; bit b5 of TA2 must be 0) and when
that the particular mode is not supported by the ACR33U-A1; the reader will reset the card to a
negotiable mode. If the card cannot be set to negotiable mode, the reader will then reject the card.
When the card ATR indicates the negotiable mode (TA2 not present) and communication parameters
other than the default parameters, the ACR33U-A1 will execute the PPS and try to use the
communication parameters that the card suggested in its ATR. If the card does not accept the PPS,
the reader will use the default parameters (F=372, D=1).
For the meaning of the aforementioned parameters, please refer to ISO 7816-3.
3.2. Memory-based Smart Cards
The ACR33U-A1 works with several memory-based smart cards such as:
•
Cards following the I2Cbus protocol (free memory cards) with maximum 128 bytes page with
capability, including:
o Atmel: AT24C01/02/04/08/16/32/64/128/256/512/1024
•
Cards with secure memory IC with password and authentication, including:
o Atmel: AT88SC153 and AT88SC1608
•
Cards with intelligent 1k bytes EEPROM with write-protect function, including:
o Infineon: SLE4418, SLE4428, SLE5518 and SLE5528
•
Cards with intelligent 256 bytes EEPROM with write-protect function, including:
o Infineon: SLE4432, SLE4442, SLE5532 and SLE5542
•
Cards with ‘104’ type EEPROM non-reloadable token counter cards, including:
o Infineon: SLE4406, SLE4436, SLE5536 and SLE6636
•
Cards with Security Logic with Application Zone(s), including:
o Atmel: AT88SC101, AT88SC102 and AT88SC1003
Note: Memory card is supported in ICC Slot 0 only of ACR33U-A1 SmartDuo Smart Card Reader.
