NXP公司的CLRC663是新一代高性能近距离非接触式读卡器,支持多种协议如MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,MIFARE Ultralight C, MIFARE PLUS和MIFARE DESFire,数据速率高达848kbps,适用于银行,电子政务,交通,移动支付等众多基础设施应用.本文介绍了CLRC663主要特性和优势,框图,应用电路以及CLEV663无接触读卡器评估板主要特性,电路图和材料清单.
The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional active circuitry. The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and CRC).
The CLRC663 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The CLRC663 supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
The CLRC663 supports layer 2 and 3 of the ISO/IEC 14443B reader/writercommunication scheme except anticollision. The anticollision needs to be implemented in the firmware of the host controller as well as in the upper layers.
The CLRC663 is able to demodulate and decode FeliCa coded signals.TheFeliCa receiver part provides the demodulation and decoding circuitry for FeliCa coded signals.
The CLRC663 handles the FeliCa framing and error detection such as CRC. The CLRC663 supports FeliCa higher transfer speeds of up to 424 kbit/s in both directions.The CLRC663 is supporting the P2P passive initiator mode in accordance withISO/IEC 18092.
The CLRC663 supports the vicinity protocol according to ISO/IEC15693, EPC UID and ISO/IEC 18000-3 mode 3/ EPC Class-1 HF.
The following host interfaces are supported:
• Serial Peripheral Interface (SPI)
• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)
• I2C-bus interface (two versions are implemented: I2C and I2CL)
The CLRC663 supports the connection of a secure access module (SAM). A dedicated separate I2C interface is implemented for a connection of the SAM. 
The SAM can be used for high secure key storage and acts as a very performant crypto coprocessor. Adedicated SAM is available for connection to the CLRC663.
The CLRC663 multi-protocol NFC frontend IC supports the following operating modes
• Read/write mode supporting ISO/IEC 14443A/MIFARE
• Read/write mode supporting ISO/IEC 14443B
• Read/write mode supporting JIS X 6319-4 (comparable with FeliCa scheme)
• Passive initiator mode according to ISO/IEC 18092
• Read/write mode supporting ISO/IEC 15693
• Read/write mode supporting ICODE EPC UID/ EPC OTP
• Read/write mode supporting ISO/IEC 18000-3 mode 3/EPC Class-1 HF

This application note gives a detailed overview of the hardware for working with the RC663 contactless reader - we use the LPCXpresso LPC1769 and the Blueboard – the installation procedures of the Development Environment and the handling of the reader projects using the NFC Reader Library.
The demo reader is made up of 2 separate boards: 
• A CLEV663B demo board (called Blueboard) provided by NXP. This is the primary platform for the RC663 reader chip and the current version is Blueboard v3.0 (see Fig 1). This board has connectors which are designed to exactly fit the ones of the companion, the LPCXpresso LPC 1769 development board. 
• A commercial LPCXpresso LPC 1769 development board (12NC: 935291912598, Type: OM13000+598) which can be provided by NXP or bought directly on the market. See Ref. [10]. All projects can be used with the LPCXpresso LPC11U68 development board (12NC: 935303579598) as well. 
The RC663 demo board embeds the contactless communication transceiver IC RC663 with all its elements needed for transmission: EMC filter, matching network and the antenna. The RC663 supports different kind of contactless communication methods and protocols at 13.56 MHz: 
• Reader/Writer mode supporting ISO/IEC14443A/MIFARE, 
• Reader/Writer mode supporting ISO/IEC14443B, 
• Reader/Writer mode supporting FeliCa scheme, 
• Passive initiator mode according to NFCIP-1 
• Reader/writer supporting ISO/IEC 15693, 
• Reader/writer supporting ISO/IEC 18000-3 Mode 3, 
• Refer to the data sheet of this IC [2] for more details
To work with the provided projects, one will also need an LPCXpresso LPC development board. Such a board is not included in the Blueboard hardware package. 
The LPCXpresso LPC1769 development board integrates an NXP ARM Cortex-M3 microcontroller LPC1769 with 512 Kbytes of Flash memory and 64 Kbytes of RAM. Among others it integrates the following peripherals: 
• Serial UART interface, 
• SPI controller, 
• I2C controller, 
• Serial Wire test/debug interface, 
• For detailed information, see LPC1769 product site [3] 
The LPCXpresso board contains a JTAG/ SWD debugger called the “LPC-Link” and a target MCU. LPC-Link is equipped with a 10-pin JTAG header and it seamlessly connects to the target via USB to the computer.
