What is Infineon Technologies?
Infineon Technologies is a semiconductor manufacturer. It designs and sells chips and related system solutions across power, sensing, control, connectivity and security. The company's own site describes it as "a world leader in semiconductor solutions," and its catalog is organized by product families and by application areas rather than by consumer devices.
What it actually makes
The product list on Infineon Technologies spans several distinct areas:
- Microcontrollers — AURIX™ TriCore™, PSoC™, TRAVEO™ T2G, XMC™, plus motor-control SoCs under MOTIX™
- Power — IGBTs, silicon and silicon-carbide diodes and thyristors, gallium nitride (GaN) devices, gate driver ICs, DC-DC converters, AC-DC conversion, intelligent power modules
- Sensors — including contactless power and sensing ICs
- Security and smart card solutions — payment, biometric payment and wearable payment chips
- Memories — NOR flash, F-RAM, nvSRAM, PSRAM, SRAM, embedded flash IP, plus radiation-hardened and high-reliability variants
- Connectivity and interfaces — USB, Bluetooth, Wi-Fi, automotive Ethernet PHYs and switches, transceivers, digital isolators
- Other — ASICs, ESD and surge protection, clocks and timing, small-signal transistors and diodes, evaluation boards
Who tends to use it
The catalog points to two main audiences. One is engineers designing products: automotive and industrial systems, power supplies, motor drives, embedded control, secure payment cards and wearables, and networking hardware. The other is buyers and technical decision-makers who need long-lived, qualified parts — visible in categories such as high-reliability, defense, space and NewSpace, and radiation-hardened memory.
A practical example: someone building an electric-vehicle motor controller might combine an AURIX™ MCU, a gate driver IC, SiC power devices and an automotive Ethernet PHY from the same vendor. Buying across one supplier can simplify qualification and supply, but it also narrows second-source options.
How to decide whether it fits
Match your requirement to the relevant product family first, then check availability, qualification level and lifecycle. Automotive and industrial parts are typically chosen for temperature range, reliability certification and long-term supply commitments; consumer or wearable designs care more about size, power draw and cost.
A useful next step is to browse the product families on Infineon Technologies and use its developer support and design resources to check reference designs, evaluation boards and toolchain fit before committing to a part. If you need broad catalog distribution and comparison across vendors, distributors such as Mouser Electronics or DigiKey list competing parts side by side.
How do I choose between AURIX, PSOC, TRAVEO, and XMC microcontrollers for my project?
Choosing among Infineon's four main MCU families comes down to the job the chip has to do, not to raw performance alone. AURIX is built for safety-critical, high-performance control; PSoC combines an MCU core with configurable analog and digital blocks; TRAVEO targets graphics, body and human-machine-interface work; and XMC is aimed at industrial real-time control and motor drive.
Quick comparison
| Family | Typical focus | Suits projects like |
|---|---|---|
| AURIX (TriCore) | High-performance, functional-safety-oriented automotive and industrial control | Motor and inverter control, domain or zone controllers, systems needing lockstep and safety documentation |
| PSoC | Programmable mixed-signal MCU with configurable blocks | Capacitive sensing, custom analog front ends, sensor hubs, small systems where you'd otherwise add discrete parts |
| TRAVEO (T2G) | Graphics, body electronics and HMI-oriented automotive MCUs | Instrument clusters, body control modules, displays and capacitive touch interfaces |
| XMC | Industrial real-time control, motor control and power conversion | Motor drives, digital power supplies, industrial automation and PLC-style I/O |
How to decide
Start with three questions:
- Is functional safety a requirement? If you need an ASIL-rated path with safety documentation and lockstep cores, AURIX is the natural starting point. The other families are used in safety-related systems too, but the certification story differs, so confirm it early.
- Do you need custom analog or mixed-signal behaviour? PSoC's configurable blocks let you define comparators, amplifiers, filters and capacitive sensing in the fabric rather than adding external components. That shortens the bill of materials but ties you to its toolchain and configuration model.
- Is the workload graphics, connectivity or hard real-time control? Graphics and body/HMI work points to TRAVEO. Tight control loops for motors or power stages point to XMC, which has peripherals designed around PWM, ADC timing and fast control response.
A concrete scenario
Suppose you are building a three-phase motor drive with a small display and a CAN interface. The control loop argues for XMC or AURIX; the display argues for TRAVEO. If the display is simple and driven over a serial link, keep the control MCU and add a small display controller. If the display is a full cluster with graphics, split the design: a TRAVEO for the HMI and an XMC or AURIX for the motor control. Splitting avoids compromising the control loop's timing for graphics work.
Practical next step
List your must-haves — safety level, analog needs, graphics, motor-control peripherals, connectivity (USB, Bluetooth, Wi-Fi), memory and package — then filter the family line-ups on Infineon Technologies and check the corresponding evaluation boards and design resources before committing. Confirming that an evaluation board and a mature toolchain exist for your exact part is usually faster than reading datasheets in isolation.
Which Infineon power solutions are best for electric vehicle powertrain and charging systems?
For EV powertrain and charging, Infineon's relevant lines split into three groups: traction and motor-control power, onboard/offboard charging conversion, and the control and sensing around them. The product families named on the site include IGBTs, silicon-carbide (SiC) diodes and thyristors, gallium nitride (GaN) devices, gate driver ICs, intelligent power modules, DC-DC converters, AC-DC power conversion, contactless power and sensing ICs, and AURIX™ TriCore™ microcontrollers.
Powertrain (traction inverter, motor control)
- Traction inverters: IGBTs and SiC diodes/thyristors are the switching devices; intelligent power modules package switches with drive and protection for compact inverter designs.
- Gate driver ICs sit between the controller and the power stage, setting switching behaviour and protection.
- Motor control: MOTIX™ motor control SoCs/SiPs and AURIX™ MCUs handle control loops; sensors cover position, current and temperature.
- High-voltage isolation matters wherever control electronics meet the traction bus.
Charging (onboard charger, DC-DC, offboard)
- AC-DC power conversion for grid-side stages; DC-DC converters for voltage conversion between the pack and low-voltage systems or within charger stages.
- SiC and GaN devices are the usual candidates when higher switching frequency, smaller magnetics or higher efficiency are the goals; IGBTs remain a common choice where cost and ruggedness dominate.
- Contactless power and sensing ICs apply to inductive charging designs.
- Security and smart card solutions are relevant to payment and authentication features in charging infrastructure, not to the power conversion itself.
How to choose
| Priority | Lean toward | Trade-off |
|---|---|---|
| Efficiency and compact charger/inverter | SiC or GaN switching devices | Higher device cost, tighter gate-drive and layout demands |
| Cost-sensitive, proven designs | IGBTs and modules | Larger, more cooling and filtering |
| Integrated, faster design-in | Intelligent power modules, MOTIX™ SoCs | Less freedom to tune the power stage |
| Functional safety and control | AURIX™ MCUs with isolation | Added complexity in software and validation |
Two practical cautions. First, voltage class and thermal path drive the choice more than brand: a 400 V and an 800 V bus lead to different device selections. Second, charging spans onboard and offboard equipment with different standards and lifetimes, so treat them as separate designs.
Next step: open the Power and Microcontroller sections on Infineon Technologies and filter by application, then confirm device ratings, isolation and qualification against your own voltage and safety requirements before shortlisting parts.
How can I use Infineon security and smart card solutions for payment applications?
Infineon's security and smart card portfolio is aimed at the chip-level side of payment: the secure element or controller inside a card, wearable or phone that stores keys, runs payment applets and performs cryptographic authentication. You would typically not buy a finished payment product here, but the silicon and supporting software that a card maker, wearable brand or terminal vendor integrates into its own certified design.
Infineon Technologies groups this under Security and smart card solutions, with payment-specific paths covering smart cards, wearables and biometric payment.
H3 Practical ways to use it
- Contactless smart cards: Use a certified secure element as the core of a dual-interface or contactless card, then load a payment applet from your scheme provider.
- Wearables: Embed a payment chip or module in a ring, band or watch so the device can emulate a card at the terminal.
- Biometric payment cards: Combine a secure element with a fingerprint sensor so the card authenticates the holder locally before authorising a transaction.
- Terminals and readers: Use security ICs for key storage, secure boot and transaction protection in POS or mobile acceptance devices.
H3 What to check before choosing
- Certification: Your end product usually needs EMVCo and scheme approval. Confirm which Infineon parts already have the relevant security certifications and reference designs.
- Applet and scheme support: Verify that your payment network's applet runs on the chosen platform, and whether you need contactless-only or dual-interface.
- Form factor: Cards, wearables and biometric cards have different power, antenna and mechanical constraints. Infineon's wearable-payment pages are a useful starting point.
- Toolchain: Check the developer support, SDKs and evaluation boards available for the specific chip family before committing.
A useful next step is to open the payment solutions area on Infineon Technologies and match your product type — card, wearable or biometric — to the listed chip families, then contact Infineon or a certified card manufacturer to confirm certification status for your target scheme.
What design resources and developer support does Infineon offer for embedded engineers?
Infineon organizes its developer-facing material around three practical needs: picking parts, designing them in, and getting software running. The site's own navigation lists a Design Resources section alongside Support & Training, and it groups products by function (microcontrollers, sensors, power, security, memories, wireless connectivity) rather than by marketing category. That structure matters if you are an embedded engineer trying to move from "which MCU family fits this motor-control board?" to a schematic and a working firmware project.
Where to start, depending on your task
- Choosing silicon: The Microcontroller section separates families by job — AURIX™ TriCore™ for automotive/functional-safety work, PSoC™ for mixed-signal and programmable systems, TRAVEO™ T2G for instrument-cluster and body electronics, XMC™ for industrial control, MOTIX™ for motor-control SoCs. Browsing by family is faster than searching a part number if you are still scoping the design.
- Design-in and evaluation: Evaluation boards appear as their own product line, and the site's product pages generally link to the related tools and documentation. For power designs, the Power section splits by topology (AC-DC conversion, DC-DC converters, gate drivers, IGBTs, SiC/GaN devices, intelligent power modules), which is the more useful axis than package type when you are sizing a converter.
- Software and toolchain: Developer Support is where the IDE, compiler, configuration and library material lives. This is the part that determines whether a family is pleasant to use day to day, so check it before committing to a part, not after.
- Account-gated material: myInfineon gives access to dashboards, bookmarks, online orders, cases and myICP. Some design collateral and support cases sit behind that login. If you are evaluating a part for a project with a hard deadline, confirm early that the documents you need are available without a lengthy approval.
A realistic scenario
Suppose you are building a sensor node with a wireless link and a small motor. You would likely check the Wireless connectivity options for the radio, the Sensor technology line for the sensing element, and MOTIX™ or XMC™ for control — then look for an evaluation board that covers the combination, and check Developer Support for the matching software stack. The trade-off is breadth: a catalog this wide means more families with different toolchains, so narrowing to one ecosystem early saves integration effort later.
A useful next step is to pick your target family first, then open its Design Resources and Developer Support pages side by side and confirm that the reference designs, configuration tool and compiler you need are all present before you design the board.

How do I order samples or evaluate Infineon products through myInfineon?
myInfineon is Infineon's account area for managing orders, bookmarks, cases and profile data, and it is the usual route for sample requests and evaluation support. You register or log in, then use the account tools to request samples, track online orders and open support cases. The site also lists developer support and design resources, which are the practical places to look for documentation, evaluation boards and tools before you commit to a part.

H3 A practical ordering sequence
- Create or sign in to your myInfineon account.
- Identify the exact part or evaluation board from the product pages, using the search tools and product information sections.
- Submit a sample request or place an online order through the account area, then track it under Online Orders.
- If the part needs configuration, software or a board, pull the relevant design resources and developer support material.
- Use My cases if a request stalls or you need application guidance.
H3 What to check before you request
- Commercial vs. engineering samples: confirm which status the part has, because sample availability and lead times differ.
- Minimum and maximum quantities: sample programmes usually cap how many units you can take per part.
- Eligibility: some parts are restricted to qualified customers or specific applications, so have your company and project details ready.
- Evaluation hardware: a sample alone may not be enough; check whether an evaluation board, reference design or software package exists for the device family.
- Account details: keep your shipping address, VAT or tax information and contact data current, since these affect order processing.
H3 When to use samples vs. a distributor Samples through myInfineon suit early prototyping, a first look at a device family, or confirming a pin-compatible alternative. For production volumes, scheduled deliveries or parts the sample programme does not cover, a franchised distributor is usually the better channel. If you need several device types together, such as a microcontroller with matching power and sensor parts, check whether the account area lets you consolidate the request or whether you should go through distribution.
A useful next step: open the product page for your target part, note its ordering code and evaluation options, then sign in and start the request from there rather than from a general contact form. That keeps the sample tied to the correct part number and makes follow-up cases easier to track.
