Product short data sheet PUBLIC Rev. 3.2 — 21 February 2011 187032 7 of 17 NXP Semiconductors MF1SPLUSx0y1 Mainstream contactless smart card IC There are three different versions of the PICC. The UID is programmed into a locked part of the NV-memory which is reserved for the manufacturer: • unique 7-byte serial number • unique 4-byte serial number • non-unique 4-byte serial number Due to security and system requirements, these bytes are write-protected after being programmed by the PICC manufacturer at production. Remark: The programmed 4-byte NUID serial number is not globally unique which has to be considered in the contactless system design. See Ref. 11 for further information regarding handling of UIDs. The customer must decide which UID length to use when ordering the product, see Table 2 for ordering information. During personalization, the PICC can be configured to support Random ID in security level 3. The user can configure whether Random ID or fixed UID shall be used. According to ISO/IEC 14443-3 (see Ref. 5), the first anticollision loop returns the Random Number Tag 08h, the 3-byte Random Number and the BCC, if Random ID is used. The retrieval of the UID in this case can be done using the Virtual Card Support Last command (see Ref. 3) or by reading out block 0. 8.2.1 Backwards compatibility protocol The backwards compatibility of this product, as used in security level 1 and security level 2, runs on the same protocol layer as MIFARE Classic 1K and MIFARE Classic 4K. The protocol is formed out of the following components: • Frame definition: according to ISO/IEC 14443-3 • Bit encoding: according to ISO/IEC 14443-2 • Error code handling: handling is proprietary as error codes are formatted in half bytes. • Command specification: commands are proprietary. Please use the specification as in Ref. 1 and Ref. 2 and the additional commands which are only implemented in MIFARE Plus as described in this document and in Ref. 3. The following security levels can run on this protocol: • Security Level 0 • Security Level 1 8.2.2 ISO/IEC 14443-4 Protocol The ISO/IEC 14443-4 Protocol (also known as T=CL) is used in many processor cards. This protocol is used for the MIFARE Plus with the following security levels: • Security Level 0: all commands • Security Level 1: only the security level switch and originality function. • Security Level 3: all commands |
