Infineon Technologies AG has launched a new series of microcontrollers (MCUs) for industrial and consumer motor control as well as power conversion system applications. The PSOC Control MCUs, based on Arm Cortex -M33 core, delivers on-board functionality that is designed to increase performance and efficiency in next-generation motor control and power conversion systems. These include home appliances, power tools, renewable energy products, industrial drives, and lighting and computing/telecom power supplies.

Key specs include clock speed of up to 180 MHz, high-performance analog-to-digital converters (ADCs), high-resolution (<100 ps) pulse-width-modulation (PWM) and an integrated CORDIC accelerator to off-load real-time control tasks from the CPU. The accelerator’s true synchronous “idle” sampling of up to 16 analog signals from the single-core ADC is reported to be up to 25 percent faster without sampling jitter.
Infineon said this combination of power and performance delivers system bill-of-material (BOM) savings, while the <10 µA deep sleep and <1 µA hibernate modes deliver energy savings for low-power and battery-driven applications.
The PSOC Control family also supports power electronics based on wide-band gap (WBG) technologies such as silicon carbide (SiC) and gallium nitride (GaN), which can enhance performance and further reduce BOM costs for the overall system, the company said.
Like all Infineon MCUs, the Infineon PSOC Control family is supported by the ModusToolbox Software development ecosystem that includes building blocks for product evaluation and production. These blocks include field-oriented control (FOC) of brushless and permanent magnet motors, power conversion algorithms (PFC, LLC, Buck, etc.) and device drivers. Also included are evaluation boards, system reference designs, debuggers and PC-based development tools.
The ModusToolbox Motor Suite adds software, tools and resources that support motor control applications. These include advanced motor control development kits and the selection of control algorithms, as well as the testing, tuning and monitoring of motor parameters.
The first two MCUs in the Infineon PSOC Control family, with CPU clock speeds of 100 MHz and 180 MHz and up to 256-KB embedded flash, are available for early access customers. General market availability is expected in the first quarter of 2025.
