View the new STM32 Value Line MCUs that bring the advantages of the STM32 32-bit advanced industry-standard core into cost-effective applications typically served by 16-bit MCUs!

The STM32 family of 32-bit Flash Microcontrollers is based on the breakthrough ARM Cortex™-M3 core - a core specifically developed for embedded applications. The STM32 family benefits from the Cortex-M3 architectural enhancements including the Thumb-2 instruction set to deliver improved performance with better code density, significantly faster response to interrupts, all combined with industry leading power consumption. ST is now the first leading MCU supplier to introduce a product family based on this core. The STM32 family is built to offer new degrees of freedom to MCU users. It offers a complete 32-bit product range that combines high performance, low power and low voltage, while maintaining full integration and ease of development.

STM32 (ARM Cortex-M3) 32-bit Microcontroller Families
    The STM32 advantages:
  • Leading-edge architecture with the latest Cortex-M3 core from ARM
  • Excellent real-time behavior
  • Outstanding power efficiency
  • Superior and innovative peripherals
  • Maximum integration
  • Easy development, fast time to market
The high level of pin-to-pin, peripheral and software compatibility across the family gives you full flexibility.

STM32, more choices:
  • The Performance Line, STM32F103, operates at 72 MHz, with more on-chip RAM and peripherals onboard. It takes the 32-bit MCU world to new levels of performance and energy efficiency. With its Cortex-M3 core at 72 MHz, it is able to perform high-end computation. Its peripheral set brings superior control and connectivity.
  • The Connectivity Line, STM32F105 / STM32F107, introduces outstanding new features, including USB 2.0 OTG Full Speed 12 Mbps, and Ethernet MAC 10/100 Mbps.
  • The USB Line, STM32F102, is a medium-density 32-bit MCU operating at 48 <Hz with high-speed embedded memories.
  • The Access Line, STM32F101, operates at 36 MHz. It is the entry point of the STM32 family. It has the power of the 32-bit MCU but at a 16-bit cost. Its peripheral set offers excellent connectivity and control.
  • The Value Line, STM32F100, combines a 24MHz ARM® Cortex™-M3 processor core with peripheral features optimized for typical 16-bit applications, such as home-entertainment products, appliances, and industrial equipment. STM32 Value Line MCUs are suitable for use in application control and user interface, medical and handheld equipment.
