ICs started a revolution in the contactless smart card business back in 1994. Today, they’re still used in a variety of applications worldwide. The MIFARE Classic EV1 represents the highest evolution of the product family and succeeds all previous versions. These solutions provide excellent ESD robustness for easy handling of the IC during inlay and card manufacturing and best-in-class RF performance for optimized transactions—allowing for more flexible antenna designs.
NXP Semiconductors has developed the MIFARE Classic EV1 contactless IC MF1S50yyX/V1 to be used in a contactless smart card according to ISO/IEC 14443 Type A. The MIFARE Classic EV1 with 1K memory MF1S50yyX/V1 IC is used in applications like public transport ticketing and can also be used for various other applications. 1.1 Anticollision An intelligent anticollision function allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without interference from another card in the field
Simple integration and user convenience The MF1S50yyX/V1 is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms. 1.3 Security and privacy • Manufacturer programmed 7-byte UID or 4-byte NUID identifier for each device • Random ID support • Mutual three pass authentication (ISO/IEC DIS 9798-2) • Individual set of two keys per sector to support multi-application with key hierarchy 1.4 Delivery options • 7-byte UID, 4-byte NUID • Bumped die on sawn wafer.
Block description The MF1S50yyX/V1 chip consists of a 1 kB EEPROM, RF interface and Digital Control Unit. Energy and data are transferred via an antenna consisting of a coil with a small number of turns which is directly connected to the MF1S50yyX/V1. No further external components are necessary. Refer to the document Ref. 1 for details on antenna design. • RF interface: – Modulator/demodulator – Rectifier – Clock regenerator – Power-On Reset (POR) – Voltage regulator • Anticollision: Multiple cards in the field may be selected and managed in sequence • Authentication: Preceding any memory operation the authentication procedure ensures that access to a block is only possible via the two keys specified for each block.
