MFRC531 ISO/IEC 14443 A Reader IC

The MFRC531 is a member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This family of reader ICs provide:

outstanding modulation and demodulation for passive contactless communication
a wide range of methods and protocols
a small, fully integrated package
pin compatibility with the MFRC500, MFRC530 and SLRC400

All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication standards are supported provided:

additional components, such as the oscillator, power supply, coil etc. are correctly applied.
standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B anticollision are correctly implemented

Using this NXP Semiconductors device according to ISO/IEC 14443 B may infringe third party patent rights.

The MFRC531 supports contactless communication using MIFARE higher baud rates (see Section 9.12 on page 38). The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for compatible transponder signals (see Section 9.10 on page 32).

The digital module, manages the complete ISO/IEC 14443 standard framing and error detection (parity and CRC). In addition, it supports the fast MIFARE security algorithm for authenticating the MIFARE products (see Section 9.14 on page 40).

The internal transmitter module (Section 9.9 on page 29) can directly drive an antenna designed for a proximity operating distance up to 100 mm without any additional active circuitry.

A parallel interface can be directly connected to any 8-bit microprocessor to ensure reader/terminal design flexibility. In addition, Serial Peripheral Interface (SPI) compatibility is supported (see Section 9.1.4 on page 9).
