简单介绍

非接触式RFID读写芯片TSC9812 This document describes the functionality and electrical specifications of the transceiver IC TSC9812. The TSC9812 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13


TSC9812  的详细介绍
  • The TSC9812 transceiver ICs support 4 different operating modes • Reader/Writer mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme • Reader/Writer mode supporting ISO/IEC 14443B • Card Operation mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme • NFCIP-1 mode Enabled in Reader/Writer mode for ISO/IEC 14443A/MIFARE, the TSC9812’s internal  transmitter part is able to drive a reader/writer antenna designed to communicate with  ISO/IEC 14443A/ MIFARE cards and transponders without additional active circuitry. The  receiver part provides a robust and efficient implementation of a demodulation and

    decoding circuitry for signals from ISO/IEC 14443A/MIFARE   compatible cards and  transponders. The digital part handles the complete ISO/IEC 14443A framing and error  detection (Parity & CRC).  The TSC9812 supports MIFARE 1K or MIFARE 4K emulation products. TSC9812 supports  contactless communication using MIFARE higher transfer speeds up to 424 kbit/s in both  directions. Enabled in Reader/Writer mode for FeliCa, the TSC9812 transceiver IC supports the FeliCa  communication scheme. The receiver part provides a robust and efficient implementation  of the demodulation and decoding circuitry for FeliCa coded signals. The digital part  handles the FeliCa framing and error detection like CRC. TSC9812 supports contactless  communication using FeliCa Higher transfer speeds up to 424 kbit/s in both directions. The TSC9812 supports all layers of the ISO/IEC 14443B reader/writer communication  scheme, given correct implementation of additional components, like oscillator, power  supply, coil etc. and provided that standardized protocols, e.g. like ISO/IEC 14443-4  and/or ISO/IEC 14443B anticollision are correctly implemented.  In Card Operation mode, the TSC9812 transceiver IC is able to answer to a reader/writer  command either according to the FeliCa or ISO/IEC 14443A/MIFARE card interface  scheme. TSC9812 generates the digital load modulated signals and in addition with an  external circuit the answer can be sent back to the reader/writer. A complete card  functionality is only possible in combination with a secure IC using the S 2 C interface. Additionally, TSC9812 transceiver IC offers the possibility to communicate directly to an  NFCIP-1 device in the NFCIP-1 mode. The NFCIP-1 mode offers different communication  mode and transfer speeds up to 424 kbit/s according to the Ecma 340 and ISO/IEC 18092  NFCIP-1 Standard. The digital part handles the complete NFCIP-1 framing and error  detection.  Various host controller interfaces are implemented: • 8-bit parallel interface  • SPI interface • serial UART (similar to RS232 with voltage levels according pad
