Microchip Low-Power NFC Bridging Reference Design Simplifies Connected Embedded Applications

Microchip has introduced a Low-Power NFC Bridging Solution Reference Design based on the PIC16F13145 microcontroller. The design provides a flexible and energy-efficient way to add NFC connectivity to embedded devices, supporting both reader-powered and self-powered modes while enabling easy sensor integration.

Key Specifications and Features

• MCU: PIC16F13145
• Power modes: NFC-reader powered or self-powered (3.3 V / 5 V via micro-USB)
• Minimum power consumption: 2.5 mA at 3.3 V (RFID tag mode)
• Default mode: Operates as NFC tag for smartphone/reader communication
• Expansion: mikroBus connector for Click Boards and Microchip development boards
• Interfaces: UART, SPI, I²C, GPIO, and analogue I/O
• Configurable Logic Block: Hardware-based functions to reduce external components
• Supports sensor connection and application-specific customization

The platform can be used for locking/unlocking, diagnostics, and sensor data checking via NFC. Its low-power architecture and flexible connectivity make it suitable for a wide range of connected embedded products.

Target Applications

• Consumer electronics
• Industrial equipment
• Automotive systems
• Smart appliances

By combining NFC bridging, configurable processing, and flexible sensing in a low-power design, this reference solution helps developers accelerate the creation of connected embedded applications.
