New Product Introduction

NXP Semiconductors NTAG 5 link® NFC forum-compliant I2C bridge

NFC Forum-Compliant I2C Bridge for IoT on Demand

NXP Semiconductors NTAG 5 link product image

NXP's NTAG 5 Link lets designers of sensor-equipped systems add an NFC interface with a wired host interface that is configurable as an I2C Master/Slave, a PWM, or a GPIO. Operating at 13.56 MHz, it is an NFC Forum-compliant contactless tag that can be read and written by an NFC-enabled device at close range and by an ISO/IEC 15693-enabled industrial reader over a longer range.
