NXP MIFARE SAM’s (Secure Access Modules) ensure the highest level of security for valuable data and transactions, converting even the simplest of readers into high security transaction devices. With on-board cryptographic co-processors leveraging 3DES, AES, RSA and PKI key capabilities, the P5DF081 NXP MIFARE SAM AV2 enables protected data and key storage with secure communication.
The NXP P5DF081 MIFARE SAM AV2 solution lets developers of smart card applications meet the needs of ever-changing security standards.
Unlike other SAM card products on the market today, MIFARE SAM AV2 has proven interoperability with all of NXP’s broad card portfolio, (JCOP Java Card, MIFARE Ultralight, MIFARE Ultralight C, MIFARE Classic EV1, MIFARE Plus, DESFire EV1, DESFire EV2 and DESFire EV3), making it the most versatile and secure SAM solution on the market today.
Secured communication
When used in combination with a reader IC supporting innovative “X” features, MIFARE SAM AV2 provides a significant boost in performance to the reader along with faster communication between reader and module. The “X” feature is a new way to use the SAM in a system, with SAM connected to the microcontroller and the reader IC simultaneously. The one variant, identified with T1AD2060, can be connected to RC52X contactless reader ICs, the other variant, identified T1AR1070, can be connected to RC663 using the X-feature. Apart from the difference in the interface, both variants have the same functionality.
The connection between the SAM and the reader is performed using security protocols based on either symmetric cryptography (TDEA and AES) or PKI RSA asymmetric cryptography. The protocols comply with the state-of-art standards and thereby ensure data confidentiality and integrity.
Available in Mini SIM (2FF) and Micro SIM (3FF).
