Introducing the PCF7991AT/1081/M118 from NXP

The PCF7991AT/1081/M118 is a state-of-the-art transponder IC designed by NXP Semiconductors, a leader in secure connectivity solutions for embedded applications. This product is part of NXP's extensive portfolio of RFID and NFC technologies that cater to a wide range of applications including access control, automotive immobilization, and asset tracking. The PCF7991AT/1081/M118 is specifically engineered to meet the high demands of passive entry and passive start systems in the automotive industry.

At the heart of this transponder IC is an advanced security mechanism that provides a robust level of protection against potential attacks. It employs a sophisticated challenge-response algorithm to ensure secure communication between the transponder and the reader. This feature is critical in preventing unauthorized access and ensuring the integrity of the system it is integrated into.

The PCF7991AT/1081/M118 operates at a frequency of 125 kHz, which is the standard for low-frequency RFID applications. Its low power consumption makes it an ideal choice for passive systems where the transponder does not have its own power source and relies on the reader to provide the necessary energy for communication. This not only extends the lifespan of the device but also contributes to a more sustainable and eco-friendly product design.

One of the key benefits of this transponder IC is its versatility. It is equipped with a configurable 32-bit serial number and offers multiple modes of operation, including Read/Write, Password, and Crypto modes, giving system designers the flexibility to tailor the security level to their specific needs. Additionally, the PCF7991AT/1081/M118 supports multi-tag reading, which is essential for scenarios where multiple transponders are present in the field of the reader.

Manufactured using high-quality materials and adhering to stringent industry standards, the PCF7991AT/1081/M118 is built for durability and long-term reliability. Its compact form factor allows for seamless integration into a variety of designs without compromising on performance or security.

Whether you're developing an automotive security system, a sophisticated access control solution, or an innovative asset tracking platform, the PCF7991AT/1081/M118 from NXP is a powerful and reliable choice that will help you achieve the highest levels of security and performance.
