For ARM Yourself with The Newest MCUs Ease-of-Design Is Key

These 32-bit ARM microcontrollers are some of the latest and greatest in this ever-improving category of workhorse MCU devices.

  • 32-Bit Microcontrollers
  • Ultra EfficienT SoCs
  • High-Performance Automotive MCUs
  • Lots of Connectivity in This Family
  • Fast Transmission Rate and Simplified Sensors
  • Security and Advanced Configurable Peripherals
  • An MCU for Intensive HMI Designs
  • Accelerated Computation Performance
  • Ultra-Low-Power with Connectivity Muscle
  • A Versatile 32-Bit MCU

The 32-bit microcontroller (MCU) has experienced ongoing innovation and growth in its capabilities for decades by incorporating the latest in semiconductor technology integration. Of course, a singular “it” doesn’t do the variety of 32-bit offerings on the market today any justice.

In this month’s Datasheet gallery you’ll find devices designed for applications ranging from automotive systems to rugged industrial environments. Plus, we have chips designed for general-purpose applications, affordability, developer accessibility, IP and data security, power efficiency, and, of course, diminutive size requirements.

If there’s a common thread, it’s the various incarnations of Arm Cortex processors to be found in these chips. Every product featured this month sports a 32-bit Arm Cortex CPU, whether an M0+, M4, M7, or M33. The domination of Arm cores has become a predictable pattern in our annual 32-bit MCU Datasheet coverage over the last few years; the industry is evidently smitten with them, for the time being.

All of the products featured in this month’s gallery were released since our last article covering these devices. As always, bear in mind that this collection represents only a small sample of the overabundance of 32-bit MCU available today. Even within individual companies, it was difficult to choose which of the many new 32-bit MCUs should be given the spotlight. My aim in their selection was to attempt to give a glimpse of the sheer breadth of functions that new 32-bit MCUs are serving.
