Keil Supports STM32 XL-Density Family


Cambridge, UK: Keil™ announce immediate support for the STMicroelectronics STM32 XL-density devices in the Keil MDK-ARM (Microcontroller Development Kit).

The STM32 XL-density product line extends the Cortex-M3 processor-based STM32 portfolio with up to 1MByte of on-chip Flash, and new features such as a Memory Protection Unit (MPU) and additional timers. The XL-Density line is pin- and software-compatible with other STM32 devices.


The latest release of MDK-ARM supports all STM32 devices and includes set-up files, device-specific views, and example projects. MDK features the industry-standard compiler from ARM, the Keil µVision4 IDE, the fully functional RTX commercial RTOS, and sophisticated analysis tools. It is specifically optimized for single-chip, high performance devices such as the STM32 family.


RL-ARM provides a comprehensive set of middleware components which enable complex applications to be easily developed using libraries for TCP/IP networking, CAN, and USB. The latest version of RL-ARM includes support for the STM32 XL-density devices from STMicroelectronics.


  • MDK-ARM v4.11 is available for download now.
  • RL-ARM 4.11 update is available now.
