FSV9505

Introduction
This data sheet describes the functionality of the FSV9505 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 FSV9505 supports all variants of the MIFARE Classic, MIFARE 1K and
MIFARE 4K RF identification protocols. To aid readability throughout this data sheet, the
MIFARE Classic,

General description
The FSV9505 is a highly integrated reader IC for contactless communication at
13.56 MHz. The FSV9505 reader IC provides:
• outstanding modulation and demodulation for passive contactless communication
• a wide range of methods and protocols
• pin compatibility with the FSV9532, FSV9501 and FSV9504 All
protocol layers of the ISO/IEC 14443 A are supported
The receiver module provides a robust and efficient demodulation/decoding circuitry
implementation for compatible transponder signals (see Section 9.10 on page 30). The
digital module, manages the complete ISO/IEC 14443 A standard framing and error
detection (parity and CRC). In addition, it supports the fast Crypto1 security algorithm for
authenticating the MIFARE products (see Section 9.12 on page 35).
The internal transmitter module (Section 9.9 on page 27) can directly drive an antenna
designed for a proximity operating distance up to 100 mm without any additional active
circuitry.
A parallel interface can be directly connected to any 8-bit microprocessor to ensure
reader/terminal design flexibility
