FSV9531

Introduction

This data sheet describes the functionality of the FSV9531 Integrated Circuit (IC). It includes the functional and electrical specifications and from a system and hardware viewpoint gives detailed information on how to design-in the device. Remark: The FSV9531 supports all variants of the MIFARE Mini, MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus RF identification protocols. To aid readability throughout this data sheet, the MIFARE Mini, MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus products and protocols have the generic name MIFARE.

General description

The FSV9531 is a highly integrated reader IC for contactless communication at 13.56 MHz. The FSV9531 reader IC provides: • outstanding modulation and demodulation for passive contactless communication • a wide range of methods and protocols • a small, fully integrated package • pin compatibility with the FSV9505 and FSV9504 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 FSV9531 supports contactless communication using MIFARE higher baud rates (see Section 9.12 on page 38). The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for compatible transponder signals (see Section 9.10 on page 32). The digital module, manages the complete ISO/IEC 14443 standard framing and error detection (parity and CRC). In addition, it supports the fast MIFARE security algorithm for authenticating the MIFARE products (see Section 9.14 on page 40). The internal transmitter module (Section 9.9 on page 29) can directly drive an antenna designed for a proximity operating distance up to 100 mm without any additional active circuitry.FSV9531 Standard ISO/IEC 14443 A/B reader solution
