  • The SILICA ST Days are here.

  • It happened that STM has updated their website, during this update STM changed the name of a few pages and the result was the loss of many links.
    Click here to see how to find the the new links.
    In my web pages I proceeded to fix the links, if any are missing, let me know.

STM brochure & flayer

ST's 8-bit microcontroller platform is implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals.
Performance: @24MHz - 6 DMIPS - 5 CoreMark
The STM8 platform supports three main product lines:
STM8S, general-purpose MCU
STM8L, ultra-low-power EnergyLite™ MCU
STM8A, automotive MCU
STM8AL, automotive ultra-low-power MCU
EvaBoard for STM8 DALI is here
STM32-STM8 embedded software solutions (update to January 2012, pdf 1.9MB), is here.

The STM32 family of 32-bit Flash microcontrollers is based on the breakthrough ARM Cortex™ M0, M3, M4 and M7 core featuring architectural enhancements with the Thumb-2 instruction set to deliver improved performance with better code density, significantly faster response to interrupts, all combined with industry-leading power savings. It offers a complete 32-bit product range while maintaining full integration and ease of development.
In addition, STM every day works to improve the STM32 EcoSystem.
