Infineon’s new NFC tag side controller integrates sensing and energy collection functions to help miniaturize battery free intelligent sensing I
2023-04-06

The built-in energy collection function of sensor controllers based on near-field communication (NFC) technology is crucial for the development of passive intelligent devices. This feature not only makes the design of IoT intelligent devices more convenient, allowing them to be used in a wide range of applications, but also improves the accuracy and efficiency of device operation. The latest NGC1081 launched by Infineon Technology Co., Ltd. (FSE code: IFX/OTCQX code: IFNNY) will further expand the product portfolio of NFC label side controllers. This new single chip IC solution can help customers in the Internet of Things industry develop lower cost and smaller intelligent edge computing/sensing devices, and ultimately bring maximum benefits to end users and manufacturers. The intelligent device designed based on NGC1081 can be powered by a mobile phone, which makes it suitable not only for medical patches and disposable fixed-point care testers, but also for wider applications such as data recorders, smart thermostats, and sensor embeddings.

The label side controller can support dual power function, allowing it to operate in passive mode (without battery) or battery powered mode based on energy collection. When operating in battery powered mode, the system can become an independent sensing node by connecting to an external power source of 3 to 3.3V. In passive mode, the entire sensing system, including the IC and its connected sensors, can obtain electrical energy by collecting energy from the NFC field of the mobile phone. The support for dual power supply function, coupled with its built-in current isolation sensing interface, not only provides unlimited possibilities for creating more innovative sensing applications without batteries and maintenance, but also is suitable for power source applications that require current isolation to meet safety requirements.

NGC1081 integrates low-power ARM ® Cortex ®- The M0 microcontroller and other key components include an NFC front-end device compatible with the ISO14443 type-A standard and an H-bridge based motor drive with a current drive capability of up to 250mA. Not only that, NGC1081 also integrates a sensing unit, which is designed based on a 12 bit SAR ADC and has 4 analog signal input ports and a 10 bit DAC analog output port. The sensing unit of NGC1081 also includes a 12V converter and a built-in temperature sensor, which can provide accuracy of ± 0.3 ℃ in the temperature range of 0 ℃ to 45 ℃, and ± 0.4 ℃ in the temperature range of -20 ℃ to 0 ℃ and 45 ℃ to 85 ℃.

NGC1081, a highly integrated single-chip solution, not only helps customers achieve smaller product designs, but also helps customers reduce the BOM cost of the entire system. In addition, with its unique IC design architecture and professional design of supporting hardware/software, customers can also design more autonomous software functions. NGC1081, with its easy to configure and diverse features, has become the best solution that can easily adapt to various applications and system specific requirements.

In addition, the system designed based on NGC1081 can seamlessly link data with mobile phones, which greatly promotes the adoption of this solution in cloud based business model products. The implementation of this seamless link feature with mobile phones mainly benefits from the streamlined and scalable concept of mailbox access, which ensures the integrity and security of data during the data access process. Moreover, specific application specific instructions and information transmitted through public protocol interfaces can further expand the protocol layer.
