MFRX85201HD/D4110: - NXP SEMICONDUCTORS

1. 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.
