TN0072 Technical note Software toolchains and STM32 features Introduction The documentation provides an overview of the STM32 devices and various toolchains. It provides information on the STM32 characteristics and how they are supported. Many features of the STM32 devices such as the STM32 peripheral description, macro and script files, and the STM32 option bytes are described in comparative tables. This description concerns all the STM32 families and their derivatives. STM32 overview The STM32 family of 32-bit Flash microcontrollers incorporates the high-performance ARM® Cortex™-M3 32-bit RISC core, high-speed embedded memories (Flash memory up to 512 Kbytes and RAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals. 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 minimal power consumption.IAR™, Hitex, Raisonance and Keil™ toolchains IAR, Hitex, Raisonance and Keil toolchains The following table provides a general information of the considered toolchains.
