About

HMI and condition monitoring sensors

Create a premium microwave user interface that feels instant, stays accurate over time, and reduces service calls. Infineon’s XENSIV™ and CAPSENSE™ solutions enable responsive touch and control, smarter energy saving, and fewer mechanical wear points.

PSOC™ Edge enables richer graphics and smarter UI behavior for differentiated products. CAPSENSE™ touch provides reliable operation even in challenging kitchen conditions and gives designers freedom to shape sleek, buttonless panels. By combining multiple sensing functions with Infineon’s Multi‑Sense approach, you can reduce chip count, PCB space, and assembly complexity. 

Radar-based presence sensing lets the microwave oven wake only when a user is nearby, cutting standby power even through glass or plastic fronts. Low-power audio sensing supports local voice or sound-trigger functions while resisting false activations. Magnetic sensing delivers smooth, precise knob/encoder control without contact, improving durability. Integrated TMR sensing can replace mechanical door switches and separate knock/position sensors, improving robustness and long-term reliability.

PSOC™ 4 Multi Sense MCU: Performance + reliability
PSOC™ Edge for display/cameras: food detection
XENSIV™ Radar: gesture and presence detection
XENSIV™ MEMS Mic: Clear voice over kitchen noise
XENSIV™ magnetic sensors: Accurate HMI control
Main system control

Build faster, more reliable microwave controllers with lower BOM and room to scale. Infineon PSOC™ and XMC™ MCUs help you deliver responsive user control, accurate power/temperature regulation, and robust connectivity while reducing external components and redesign risk. 

PSOC™ programmable analog/digital functions integrate common “glue” logic and sensor conditioning, cutting parts and PCB space. The PSOC™ 4 family supports quick reuse across models through a common tool/software approach and compatible options, shortening time to market, while its flexible digital routing lets you add or change interfaces and functions without major hardware changes. For higher-end designs, PSOC™ 6 provides extra headroom for advanced control and richer user interface tasks without sacrificing power efficiency. 

When tight real-time regulation matters, XMC™ 1000 speeds control calculations to improve stability and responsiveness for multi‑zone heating and temperature management.

XMC™ MCUs: Simplify system management
Connectivity and security

Turn microwaves into secure, reliable smart appliances—without adding complexity. Infineon combines AIROC™ wireless connectivity with OPTIGA™ hardware security so you can enable app control, remote monitoring, and cloud features while protecting users and your brand.

AIROC™ Wi‑Fi + Bluetooth® combos (Wi‑Fi 4 to Wi‑Fi 6E, Bluetooth® 5.4) provide robust connections for remote microwave oven management, software-enabled features, and online recipe services. For simpler IoT designs, AIROC™ connected MCUs integrate the wireless and control in one compact device, reducing BOM and speeding development. 

OPTIGA™ Trust M adds hardware-rooted protection for secure boot, authenticated updates, and protected key storage—helping prevent eavesdropping, data tampering, and unauthorized firmware installs. Optimized multi‑protocol co‑existence improves reliability when Wi‑Fi and Bluetooth run together, while broad interoperability with cloud ecosystems eases integration. Built-in product analytics can deliver real-time fleet insights to improve reliability and service over time.

AC-DC power conversion 

Power your microwave’s electronics efficiently and reliably with Infineon CoolSET™ auxiliary power solutions. By integrating key power functions into a single device, CoolSET™ helps you shrink the power supply, reduce component count, and simplify your design—supporting sleeker products and faster development.

Designed for today’s energy regulations, CoolSET™ delivers strong efficiency in both active use and standby, helping lower overall power consumption and keep internal temperatures under control. Built-in safety and protection features add resilience against line disturbances and everyday kitchen conditions, improving long-term reliability and reducing service returns.

CoolSET™ is ideal for supplying the always-on rails that run the user interface, control board, sensors, relays, and connectivity modules, ensuring stable operation and a consistent user experience. With Infineon’s proven appliance expertise and ready-to-use design resources, you can speed time to market with confidence.

CoolSET™: Fewer parts, higher efficiency
Inverter solutions

Design high‑efficiency, responsive microwave inverters with Infineon’s control and power portfolio. PSOC™ Control C3 and PSOC™ 4 provide flexible real‑time control for power regulation, fan and motor control, and system supervision, helping deliver faster heating response, tighter power accuracy, and consistent cooking results across mains conditions. For cost‑optimized or scalable inverter platforms, XMC™ microcontrollers add robust control performance and broad peripheral support, enabling easy reuse across product tiers.

On the power stage, EiceDRIVER™ gate drivers ensure clean, reliable switching and strong protection, improving EMI behavior and reducing stress on the power devices. Pair them with Infineon reverse‑conducting IGBTs for rugged, proven performance in demanding appliance environments, or with GaN HEMTs to push efficiency and power density for smaller, cooler designs. Together, these solutions reduce component count, simplify design-in with proven reference designs, and help you meet energy regulations while delivering quieter operation, higher reliability, and a premium user experience.

PSOC™/XMC™: Quieter, efficient fan control
EiceDRIVER™: Flexible, high-performance control
Reverse-conducting IGBT: Rugged, low-loss power
GaN HEMT: Smaller, cooler, ultra-high efficiency
