Introduction

The FSV9523 is a highly integrated reader/writer for contactless communication at 13.56 MHz. The FSV9523 reader supports ISO/IEC 14443 A/MIFARE mode. The FSV9523’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE 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/MIFARE compatible cards and transponders. The digital module manages the complete ISO/IEC 14443 A framing and error detection (parity and CRC) functionality. All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication standards are supported provided: additional components, such as the oscillator, power supply, coil etc are correctly applied standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B anticollision are correctly implemented The FSV9523 supports contactless communication using MIFARE higher baud rates (see Section 8.3.4.11 on page 22) at transfer speeds up to 848 k Bd in both directions. The following host interfaces are provided: • Serial Peripheral Interface (SPI) • Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply) • I2C-bus interface
