NXP MIFARE Classic EV1 1K RFID Card

The NXP MIFARE Classic EV1 1K is a 1 KB contactless smart card IC designed for ISO/IEC 14443 Type A applications. NXP lists the EV1 family with 1 KB and 4 KB EEPROM configurations and security features including mutual three-pass authentication and individual keys for sectors.

The 1K version is commonly associated with the MIFARE Classic S50 designation.

Available card formats can include:

• CR80 standard PVC card
• White blank RFID card
• Custom printed RFID card
• Personalized RFID card
• Contactless NFC card
• RFID keyfob
• Custom RFID form factors

NXP MIFARE Classic EV1 4K RFID Card

The NXP MIFARE Classic EV1 4K, commonly associated with the S70 designation, provides 4 KB EEPROM for applications requiring more memory than the 1K version.

The EV1 4K IC supports ISO/IEC 14443 Type A contactless communication, 13.56 MHz operation and 106 kbit/s data transfer.

Choose MIFARE Classic EV1 4K when your application requires the larger available memory configuration.

MIFARE Classic Mini S20 RFID Card

MIFARE Classic Mini, commonly identified as S20, is a smaller-memory member of the MIFARE Classic family.

It can be considered for applications where the available memory of a 1K or 4K MIFARE Classic card is unnecessary and a compact RFID credential is required.

NXP’s product information specifies 1 KB–4 KB EEPROM across the MIFARE Classic EV1 family.

MIFARE Classic 4-Byte UID and 7-Byte UID

UID configuration is an important purchasing specification when replacing an existing RFID card or integrating cards into an established reader system.

NXP documentation for MIFARE Classic EV1 describes 7-byte UID and 4-byte NUID delivery options.

Therefore, buyers should specify the required UID configuration before purchasing:

• MIFARE Classic EV1 1K 4-byte UID
• MIFARE Classic EV1 1K 7-byte UID
• MIFARE Classic EV1 4K UID configuration
• UID personalization requirements
• Original NXP chip requirement

If your existing access-control or RFID system requires a particular UID format, provide the reader/system specification when requesting a quotation.
