Integration of high-voltage functions such as 12V regulators and advanced analog functions such as inductive sensing
Based on ARM® Cortex®-M0+ processor · Includes up to 128KB of embedded flash

Infineon Technologies (hereinafter Infineon) is actively responding to the growing need for small form factor, highly integrated ICs due to intensifying electronic circuit space constraints in automobiles.

Infineon announced on the 13th that it is launching the PSoC™ 4 HVMS automotive microcontroller family.

In the automotive industry, security and functional safety are playing an increasingly important role, even in low-cost microcontroller applications.

At the same time, car manufacturers are replacing mechanical buttons on the cockpit or steering wheel with touch surfaces.

As a result, as space constraints on electronic circuits became more severe, there was a need for highly integrated ICs with small form factors.

Infineon's PSoC™ 4 HVMS family integrates high-voltage functions (12V regulators and LIN/CXPI transceivers) and advanced analog functions (CAPSENSE™, inductive sensing) and meets ISO26262 and ISO21434.

This product family includes touch buttons, sliders, and touch controls for HVAC, interior lighting, power windows/sunroofs, and door handles.Suitable for touch-type automotive HMIs with a touchpad.

PSoC 4 HVMS can also be used for touch sensing on the steering wheel or for safety-critical hands-off detection.

In addition, the latest generation CAPSENSE module supports proximity detection for occupant detection or foot kick control (a function to open the trunk with a foot movement).

In addition to HMI applications, the PSoC 4 HVMS can be used for general sensing applications (liquid level detection, Wheatstone bridge sensing, etc.) and simple actuators such as PTC heaters and internal/external lighting.

The PSoC 4 HVMS product family is AEC-Q100 certified and is available in a small footprint QFN package with a wettable flank.

In addition, these ICs provide scalability and pin compatibility with various configurations.

It meets ISO26262 ASIL-B, ensuring safe operation at temperatures up to 125°C.

It is based on an ARM® Cortex®-M0+ processor and includes up to 128KB of embedded flash and 16KB of SRAM.

It is powered directly from a 12V battery and includes LIN and CXPI PHY.

For capacitive sensing applications, the latest 5th generation CAPSENSE technology is supported with an SNR 8 times better than the previous generation, high parasitic capacitance of up to 3000pF, and overlay of up to 18mm.

Additional analog functions include a 12-bit SAR ADC, up to two operational amplifiers, and a low-power comparator.

Automotive peripheral drivers along with microcontroller product familiesIt supports comprehensive software including the library (AutoPDL), the automotive middleware library for CAPSENSE, and the safety library for the vehicle PDL (SafeTlib).

Therefore, we significantly reduce the customer's development time to accelerate the launch period.

This software package was developed in compliance with 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 was developed as a Safety Element out of Context (SEooC) for applications that meet ISO26262 and aim for a maximum ASIL-B.

The ModusToolbox™ software development platform is also scheduled to be released soon.

The PSoC 4 HVMS product family is currently supplying samples of 64K and 128K products and is scheduled to begin mass production in 2024.
