SoC-Based MCU and Smart Battery-Management Software Devoted to Advanced EVs
The PSOC 4 HVPA-SPM 1.0 microcontroller is designed for use in high-voltage Li-ion battery-management systems for electric vehicles (xEVs). The MCU, developed by Infineon Technologies, combines precision, safety, and programmability, while supporting zonal architectures and the transition to software-defined vehicles (SDVs).
Infineon is partnering with Munich Electrification, a provider of innovative battery-management software, to deliver advanced, cost-efficient battery-management-system (BMS) solutions.
The PSOC 4 HVPA-SPM 1.0, a Cortex-M0+-based MCU, integrates high-precision monitoring of current, voltage, and temperature. It works to ensure reliable battery performance, improving the accuracy of state of charge (SoC) and state of health (SoH).
Fully compliant with ASIL D (ISO 26262) safety standards, the microcontroller promotes robust and reliable operation in critical high-voltage battery systems. Its M0+ processor delivers faster data processing, which reduces the load on the central electronic control unit (ECU) and supports zonal architectures used in advanced EV designs.
Munich Electrification teamed with Infineon to deliver its “Smart Edge BMS Software” for smarter and more efficient BMS. The collaboration leverages Infineon’s semiconductor technology and Munich Electrification’s software expertise. When combined with Infineon’s processor, the resulting system reduces costs and complexity while enabling faster and safer development of next-generation electric vehicles.
Engineering samples of the PSOC 4 HVPA-SPM 1.0 are already available with qualified samples expected by Q1 2026.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
Lee also writes the regular PowerBites series.
