May 09 2023

Infineon launched NGC1081 to 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.

NGC1081 NFC Tag Side Controller for Smart Sensing Applications

The NGC1081 is a microcontroller with integrated NFC connectivity, sensing capabilities, and energy harvesting functions. It integrates a low-power ARM® Cortex®-M0 microcontroller and some other key components, including an ISO144443 type-A compliant NFC front-end device and an H-bridge-based motor driver with a current drive capability of up to 250mA. In addition, a sensing unit based on a 12-bit SAR ADC is integrated, with 4 analog signal input ports and a 10-bit DAC analog output port. The sensing unit also includes a 12V converter and a built-in temperature sensor, which can provide ±0.3°C accuracy in the temperature range of 0°C to 45°C, at -20°C to 0°C and 45°C to 85°C Offers ±0.4°C accuracy over temperature.

The built-in energy harvesting function of the sensor controller based on near field communication (NFC) technology is very important for the development of passive smart devices, which not only facilitates the design of smart devices for the Internet of Things, but also improves the working accuracy and efficiency of the devices. The IC solution further expands Infineon's portfolio of NFC tag side controllers. Smart devices designed based on NGC1081 can be controlled and powered by mobile phones, and are suitable for applications such as medical patches, disposable point-of-care testers, data loggers, smart thermostats, and sensor inlays.

Applications of NGC1081

▪ Battery-free sensing nodes, sensor inlays

▪ NFC data, temperature loggers

▪ Vital NFC sensing (e.g. health care/medical patches)

▪ Smart NFC thermostats

▪ Galvanically isolated sensor frontends

▪ NFC programming interface of electronic devices


NFC Tag Side Controllers are special type of secure element, typically found in Near Field Communication (NFC) Tag and stickers. They are designed to authenticate the user, secure communications and configure the NFC Tag. It can be used to store application data, secure data, and act as an authentication token to enable secure transactions.

Infineon's family of NFC tag-side controllers includes single-chip solutions for developing cost-effective, miniaturized, actuation or sensing applications operating in passive or active mode. The tag side controller can support dual power supply function, allowing it to work in passive mode based on energy harvesting or battery powered mode.

When working in battery-powered mode, the system can become an independent sensing node by connecting a 3 to 3.3V external power supply. In passive mode, the entire sensing system including the IC and its connected sensors can be powered by harvesting energy from the NFC field of the phone. Supporting dual power supply functions coupled with its own galvanically isolated sensing interface, these features not only provide unlimited possibilities for creating more battery-free, maintenance-free innovative sensing applications, but are also suitable for those who need to meet safety requirements power applications requiring galvanic isolation.

With its unique IC design architecture and professionally designed supporting hardware/software, it allows customers to design more autonomous software functions and realize smaller product designs.

The system designed based on NGC1081 can seamlessly link data with mobile phones, which is more conducive to the adoption of cloud business models. Thanks to the streamlined and scalable mailbox access concept, data integrity and security are ensured during data access. In addition, application-specific commands and messages transmitted through the open protocol interface can further extend the protocol layer.
