Infineon Technologies introduces the PSoC 4 HVMS family of automotive microcontrollers(MCUs). With this rollout of the Automotive MCUs Family, Infineon aims to enable automobile manufacturers to replace traditional mechanical buttons with touch-enabled surfaces that seamlessly merge into a sleek cockpit or steering wheel design.
Focusing on the significance of security and functional safety in low-end microcontroller applications, the new PSoC 4 HVMS family of automotive MCUs integrates:
- High voltage features (12 V-regulator and LIN/CXPI-transceiver).
- The automotive MCUs family combines advanced analog features (CAPSENSE™, Inductive sensing), ISO26262 compliant and ISO21434 ready.
- In steering wheels, the PSoC 4 HVMS is used for touch sensing as well as safety-critical hands-off detection.
The PSoC 4 HVMS family is AEC-Q100 qualified and offered in small footprint QFN packages with wettable flanks. The ICs offer:
- Scalability and pin compatibility across devices.
- ISO26262 ASIL-B compliance.
- Ensures safe operation at temperatures up to 125°C.
- Family is based on ARM® Cortex®-M0+ processors with up to 128 KB of embedded flash and 16 KB of SRAM.
- The MCUs can be powered directly from a 12 V battery and include LIN and CXPI PHY.
- For capacitive sensing applications, the device supports the latest 5th generation CAPSENSE technology with eight times better SNR than the previous generation.
Support for high parasitic capacitance up to 3000 pF and support for overlays up to 18 mm. Additional analog integration includes a 12-bit SAR ADC, up to two operational amplifiers and low power comparators.
PSoC 4 HVMS Family of Automotive MCUs Software Support
The Automotive MCUs Family is accompanied by comprehensive software support including Automotive Peripheral Driver Library (AutoPDL), Automotive Middleware Library for CAPSENSE, and the Safety Library (SafeTlib) for Automotive PDL, accelerating the time-to-market by significantly reducing customer development time.
The software package is developed in adherence to automotive software development processes, including ASPICE, MISRA2012 AMD1, and CERTC coding standards, and guarantees industry-leading reliability and compliance.
The PSoC 4 HVMS software package is ISO26262 compliant and developed as a Safety Element out of Context (SEooC) for applications with safety targets up to ASIL-B. The ModusToolboxTM software development platform will be additionally available soon.
Key Applications Include:
- Target applications include touch-enabled automotive HMIs (Human Machine Interfaces) with touch buttons, sliders, and touchpads for controlling HVAC, interior lighting, power windows/sunroofs or in door handles.
- The latest generation CAPSENSE module also supports proximity detection for occupant detection or foot kick control.
- In addition to HMI applications, the PSoC 4 HVMS is also used in generic sensing applications (such as liquid level sensing, Wheatstone bridge sensing, etc.) or in simple actuators such as a PTC heater or interior/exterior lighting.
Availability of the New Automotive MCUs Family
Samples of the PSoC4 HVMS controllers are available for both the 64 K and 128 K families. The series is expected to go into production in 2024. More information is available at https://www.infineon.com/psochv.
Infineon at Embedded World
Embedded World will take place in Nuremberg, Germany, from 9 to 11 April, 2024. Infineon will present its products and solutions for decarbonization and digitalization in hall 4A, booth #138 and virtually. Company representatives will also hold several TechTalks as well as presentations at the accompanying Embedded World Conference, followed by discussions with the speakers.
