Arm specializes in developing high-performance, energy-efficient central processing unit (CPU) products and related technologies. Our designs are licensed worldwide, enabling advanced computing across a diverse range of devices. Notably, over 99% of the world’s smartphones utilize Arm’s energy-efficient CPUs, contributing to a cumulative total of more than 300 billion chips powering everything from tiny sensors to powerful supercomputers.
Products offered by Arm
Besides that, we also provide software and tools, including our embedded C/C++ toolchain (Arm Compiler for Embedded), Arm Development Studio (for any Arm-based device), and Keil MDK, specifically developed for creating, building, and debugging embedded applications on Arm Cortex®-M-based microcontrollers.
Further components include:
- Free-of-charge Keil® MDK for STM32C0/F0/G0/L0/U0/WL, BlueNRG-1/2/LP/LPS
- Keil MDK supporting all STMicroelectronics’ Arm-based devices
- MDK-Middleware, professional stacks for popular peripherals
- Arm Development Studio (including Arm Compiler) for STM32MP1/MP2
- Arm FuSa RTS for functional safety applications to be used with X-CUBE-STL
- ULINKplus™ debug adapter for power aware debugging and serial-wire trace
- ULINKpro™ debug and trace adapter for powerful instruction trace with code coverage, performance analysis, and execution profiling
