The document provides a detailed description of the functionality and electrical specifications of the contactless reader/writer IC CLRC663.
It is a highly integrated transceiver IC for contactless communication at 13.56 MHz and supports various operating modes including ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, JIS X 6319-4, ISO/IEC 15693, ICODE EPC UID/EPC OTP, and ISO/IEC 18000-3 mode 3/EPC Class-1 HF.
The IC is capable of driving a reader/writer antenna designed to communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional active circuitry.
It also supports MIFARE Classic, MIFARE Ultralight, MIFARE PLUS, MIFARE DESFire, and FeliCa products.
The CLRC663 also supports P2P passive initiator mode, vicinity protocol, and various host interfaces including SPI, Serial UART, and I2C-bus.
Additionally, it features high RF output power, low-power card detection, and compliance to EMV contactless protocol specification.
The document also includes quick reference data, ordering information, block diagram, pinning information, and functional description of the IC.
