Infineon Technologies Launches Programmable High Voltage PSoC™ 4 HVMS Series

Suitable for intelligent sensing applications such as touch-screen HMI, further expanding the automotive product line

[Munich, Germany, May 9, 2024] Information security and functional safety play an increasingly important role in the automotive industry, even in low-end microcontroller applications. At the same time, automakers are replacing mechanical buttons with touch surfaces to achieve simple cockpits and steering wheels. As a result, the space for electronic circuits is greatly limited, requiring highly integrated, small-form-factor integrated circuits (ICs). To meet these challenges, Infineon Technologies AG, a global semiconductor leader in power systems and the Internet of Things, has launched the PSoC™ 4 HVMS series of automotive microcontrollers. The series integrates high-voltage functions (12 V regulator and LIN/CXPI transceiver) and advanced analog functions (CAPSENSE™ inductive sensing technology), complies with the ISO26262 standard and supports the ISO21434 standard.

PSoC™ HV MS

Target applications for this family of products include touch-enabled automotive HMIs (Human Machine Interfaces) with touch buttons, sliders and touchpads, capable of controlling HVAC, interior lighting, power windows/sunroofs and door handles. In steering wheels, PSoC™ 4 HVMS can be used for touch sensing as well as safety-critical hands-off detection. The latest generation of CAPSENSE™ modules also supports proximity detection for occupant detection or kick control. In addition to HMI applications, PSoC™ 4 HVMS can also be used for general sensing applications (such as level sensing, Wheatstone bridge sensing, etc.) and simple actuators (such as PTC heaters and interior and exterior lighting).

The PSoC™ 4 HVMS family is AEC-Q100 qualified and comes in a small footprint QFN package with wettable flanks. The ICs are scalable and pin-compatible across devices, meet ISO26262 ASIL-B standards, and can operate safely at temperatures up to 125°C . The family features an ARM® Cortex®-M0+ processor with up to 128 KB of embedded flash and 16 KB of SRAM. The microcontrollers can be powered directly from a 12 V battery and include LIN and CXPI PHYs. For capacitive sensing applications, the devices support the latest fifth-generation CAPSENSE™ technology, which has an SNR eight times higher than the previous generation, supports high parasitic capacitance up to 3000 pF and a maximum stackup of 18 mm. Additional analog integration includes a 12-bit SAR ADC, up to two operational amplifiers, and low-power comparators.

This microcontroller series is equipped with comprehensive software support, including the Automotive Peripheral Driver Library (AutoPDL), CAPSENSE™ automotive middleware library, and the safety library (SafeTlib) for automotive PDL, which can significantly reduce customers' development time and accelerate time to market . The software package is developed in accordance with the automotive software development process, including ASPICE, MISRA2012 AMD1 and CERTC coding standards, to ensure industry-leading reliability and compliance. The PSoC™ 4 HVMS software package complies with the ISO26262 standard and is an independent safety element (SEooC) developed for applications with safety goals up to ASIL-B. In addition, the ModusToolboxTM software development platform will also be launched soon.

Availability

PSoC™4 HVMS controllers are sampling in 64 K and 128 K families. Production is expected to begin in 2024.
