STM32C552 in STM32 Family
The STM32C552 sub-family from STMicroelectronics is a series of mainstream 32-bit microcontrollers based on the Arm Cortex-M33 core. Operating at frequencies up to 144 MHz, these MCUs bridge the gap between entry-level performance and high-end processing, featuring TrustZone technology for enhanced security. They are designed for cost-sensitive applications requiring efficient computational power, advanced digital peripherals like I3C and FDCAN, and reliable connectivity in a compact power footprint for modern industrial and consumer electronics.
