MCUs specializing in motor management, energy conversion

A brand new household of microcontrollers goals to reinforce the precision and efficiency of motor management and energy conversion in client and industrial functions by integrating real-time capabilities and new options. The functions these management MCUs goal embrace dwelling home equipment, drones, energy instruments, renewable vitality merchandise, industrial drives, and lighting in addition to server and telecom energy provides.

Infineon’s PSOC management MCUs, constructed round Arm Cortex-M33 core, speed up present measurement, waveform era, and real-time operations with intensive on-board analog performance, high-performance timers, and {hardware} math acceleration. Begin with a 12 Msps analog-to-digital converter (ADC) that ensures exact present and voltage measurement and real-time operation.

Subsequent, Infineon has upgraded the timer IP to enhance velocity and backbone. Timers with <100 ps pulse-width modulation (PWM) decision enable clear waveform era with excessive f_SW scalability. These waveforms assist larger switching frequencies and allow smoother management of motors throughout velocity and torque.

That makes the management MCUs vast bandgap (WBG) prepared, implying that these MCUs assist larger switching frequencies required to regulate WBG gadgets like silicon carbide (SiC) and gallium nitride (GaN). “Many MCUs are usually not capable of ship larger frequencies once they interface with SiC and GaN gadgets,” stated Steve Tateosian, SVP of IoT and industrial MCUs for IoT, Wi-fi and Compute Enterprise at Infineon Applied sciences.

One other outstanding function in these management MCUs is the mixing of the CORDIC accelerator to dump real-time management duties from the CPU. The CORDIC accelerator facilitates synchronous “idle” sampling of as much as 16 analog alerts from the single-core ADC and that’s as much as 25% quicker with out sampling jitter.

“Basic-purpose CPUs typically don’t deal with motor management effectively,” Tateosian stated. “So, we put some further {hardware} to speed up among the particular capabilities for motor management use instances and thus enhance real-time management functionality of those MCUs.”

These MCUs are PSA L2 licensed for safety, and for security, Infineon offers Class B and SIL 2 compliant libraries for self checking, thus making certain that the system is working because it’s speculated to function.

The PSOC management MCUs include analysis boards, system reference designs, debuggers, and a complete household of PC-based growth instruments. These motor management MCUs are additionally supported by the ModusToolbox software program platform, which encompasses field-oriented management (FOC) for brushless and everlasting magnet motors, energy conversion algorithms equivalent to PFC, LLC and Buck, and machine drivers.

The primary two MCUs within the PSOC management household—with CPU clock speeds of 100 MHz and 180 MHz and as much as 256 KB embedded flash—are actually obtainable for early-access prospects. Full market availability of C3P2 and C3M3 management MCUs is deliberate through the first quarter of 2025.
