General description

 

The MFRX852 is a new highly integrated security reader module for contactless communication at 13.56 MHz. It combines a completely integrated Secure Application Module (SAM), data processing and modulation/demodulation for high security passive contactless communication methods and protocols at 13.56 MHz.

The MFRX852 supports the following contactless protocols and features:

  • all layers of the ISO/IEC 14443 including the type A and type B communication scheme
  • contactless T=CL protocol for MIFARE DESFire communication
  • contactless communication using higher baud rates

The MFRX852 is primarily designed for secure transport applications and related loyalty programs. Other possible applications are for example, general secure reader applications, Automatic Fare Collection (AFC) terminals, value checkers, ePassport readers and security handheld readers.

It supports the MIFARE Mini, MIFARE 1K, MIFARE 4K security algorithm to authenticate MIFARE Mini, MIFARE 1K, MIFARE 4K products. In addition, DES/3DES and AES security algorithms are supported to authenticate NXP MIFARE DESFire and MIFARE DESFire EV1 products. Additional immunity against security attacks is provided by the high integration of security processor and contactless interface into a single module package.

Reduced complexity of security reader design, hardware and software development is achieved by high integration of several hardware components into one small module package of 7 mm × 7 mm.
