ST25R95-VMD5T

The ST25R95-VMD5T is an advanced NFC (Near Field Communication) frontend integrated circuit (IC) developed by STMicroelectronics. It is designed to enable efficient and reliable communication between NFC-enabled devices and NFC tags or cards, facilitating various contactless applications such as mobile payment, access control, ticketing, and smart packaging.

Key Features:

• NFC Frontend: Acts as the interface between an NFC reader (such as a smartphone or NFC reader/writer device) and NFC tags or cards, enabling bidirectional communication for data exchange and interaction.
• ISO/IEC 14443 and ISO/IEC 15693 Support: Compliant with international NFC standards, including ISO/IEC 14443 Type A/B and ISO/IEC 15693, ensuring interoperability with a wide range of NFC devices and tags.
• High Frequency (HF) Operation: Operates at the HF frequency band (13.56 MHz), the standard frequency for NFC communication, providing compatibility with existing NFC infrastructure and devices.
• Integrated Analog Frontend: Incorporates a highly integrated analog frontend with RF (Radio Frequency) signal conditioning and modulation/demodulation circuits, optimizing signal quality and reliability in challenging RF environments.
• Antenna Management: Supports dynamic antenna tuning and impedance matching techniques to maximize the efficiency of antenna coupling and improve communication range and reliability.
• Low-Power Operation: Designed for low-power operation, featuring power-saving modes and optimized power management circuits to minimize energy consumption in battery-powered NFC devices.
• Advanced Data Handling: Implements advanced data handling features such as automatic collision avoidance, anti-collision protocols, and error detection/correction mechanisms to ensure robust and reliable data transfer in noisy or congested NFC environments.
• Integrated Security Features: Includes built-in security features such as encryption, authentication, and secure key management to protect sensitive data and prevent unauthorized access or tampering.
• Flexible Interface: Provides a flexible interface for seamless integration with host microcontrollers, processors, or NFC-enabled devices, supporting standard communication protocols such as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).
• Compact Package: Offered in a compact and space-saving package, suitable for integration into small-form-factor electronic devices, PCBs (Printed Circuit Boards), and modules with limited space constraints.

Applications:

• Mobile Payment: Used in NFC-enabled smartphones, tablets, and wearable devices for secure mobile payment transactions, digital wallet applications, and peer-to-peer (P2P) payment services.
• Access Control and Security: Deployed in access control systems, electronic locks, and security gates for contactless authentication, employee identification, and building entry/access management.
• Ticketing and Transportation: Employed in ticketing systems, public transportation terminals, and toll collection systems for contactless ticketing, fare payment, and passenger authentication in buses, trains, and metros.
• Smart Packaging and Retail: Integrated into smart packaging solutions, product authentication labels, and retail POS (Point of Sale) terminals for NFC-based product information, marketing campaigns, and customer engagement.
• IoT (Internet of Things) and Smart Devices: Embedded in IoT devices, smart appliances, and connected gadgets for NFC-based device provisioning, configuration, and data exchange in smart home, industrial IoT, and healthcare applications.
• Asset Tracking and Inventory Management: Utilized in asset tracking systems, inventory management solutions, and supply chain logistics for NFC-based asset identification, tracking, and traceability of goods and assets.
