The NXP PCF7991AT/1081/N is a versatile RFID (Radio-Frequency Identification) transponder IC designed for use in a wide range of applications requiring secure and reliable wireless communication. This advanced integrated circuit is a key component in systems that need to perform identification and tracking tasks, such as access control, asset management, and contactless payment systems.

Key Features

• Frequency: Operates at 125 kHz, a common frequency for low-power RFID applications, ensuring compatibility with existing infrastructures and readers.
• Modulation Techniques: Supports ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying) modulation techniques, providing flexibility in communication protocols and enhancing data integrity during transmission.
• Security: Equipped with advanced security features, including a unique ID and multi-purpose memory, which can be locked to prevent unauthorized access to sensitive data.
• Power Source: This passive RFID transponder IC does not require an internal power source, as it draws the necessary energy from the reader's interrogating signal, making it ideal for low-maintenance and long-lasting applications.
• Package: Comes in a small, leadless HVSON-8 package, which is ideal for space-constrained applications and ensures robust performance even in harsh environmental conditions.

Applications

The PCF7991AT/1081/N is suitable for a variety of applications, including:

• Access control systems (e.g., keyless entry, security badges)
• Animal identification tags
• Asset tracking and inventory management
• Automotive immobilizer systems
• Contactless smart cards and tokens
