MFRC531 is part of the latest family of highly integrated reader ICs that enable contactless communication at 13.56 MHz. This series of reader ICs provides:
-
出色的调制和解调性能,可实现无源非接触式通信
-
各种方法与协议
-
全集成式小型封装
-
与MFRC500、MFRC530和SLRC400针脚兼容
Communication standards that support all ISO/IEC 14443 A and ISO/IEC 14443 B protocol layers:
-
正确安装振荡器、电源、线圈等额外组件。
-
正确部署ISO/IEC 14443-4和/或ISO/IEC 14443 B防冲突等标准化协议
Use of this NXP semiconductor device in accordance with ISO/IEC 14443 B may infringe third-party patent rights.
MFRC531 supports contactless communication using MIFARE's higher baud rate (see section 9.12 on page 38). The receiver module provides a stable and efficient demodulation/decoding circuit scheme that is compatible with transponder signals (see section 9.10 on page 32).
The digital module manages the full SO/IEC 14443 standard framing and error detection (parity and CRC). In addition, it supports the Fast MIFARE security algorithm for authenticating MIFARE products (see section 9.14 on page 40).
The internal transmitter module (see section 9.9 on page 29) directly drives the antenna designed for close work up to 100 mm without any additional active circuitry.
The parallel interface can be directly connected to any 8-bit microprocessor to ensure flexibility in the reader/terminal design. In addition, Serial Peripheral Interface (SPI) compatibility is supported (see Section 9.1.4 on page 9).
