GT23SC55460 Reader/Writer IC conformto ISO/IEC 14443A and widely used in NFC payment environment

2021-02-09
●GT23SC55460 is a highly integrated reader/writer IC for contactless communication at 13.56 MHzand supports ISO/IEC 14443 A mode. GT23SC55460’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A cards and transponders without additional active circuitry. The receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO/IEC 14443 A compatible cards and transponders. The digital module manages the complete ISO/IEC 14443A framing and error detection (parity and CRC) functionality. GT23SC55460 supports the lowest power supply minimum to 2.5V.
●Features:
■Conform to ISO/IEC14443A
■Highly integrated analog circuitry to demodulate and decode responses
■13.56MHz operating frequency
■106kbit/s data transferrate
■I2C/SPI/UART bus interface for host connection
■Programmable Timer
■Internal oscillator
■FIFO buffer handles 64 byte send and receive
■Typically operating distance in Reader/Writer mode up to 50mm depending on the antennasize and tuning
■2.5V to 3.3V power supply
■CRC coprocessor
