Microcontrollers exhibit core benefits

32bit Flash microcontrollers are based on ARM Cortex-M3 core for embedded applications requiring a combination of high performance, low power and low cost.

STMicroelectronics has a new family of 32bit Flash microcontrollers based on the breakthrough ARM Cortex-M3 core - a core with features specifically designed for embedded applications requiring a combination of high performance (1.25DMIPS/MHz), low power and low cost The STM32 family benefits from the Cortex- M3's many new architectural enhancements including the Thumb-2 instruction set to deliver improved performance combined with better code density, and a tightly coupled nested vectored interrupt controller for significantly faster response to interrupts, all combined with industry leading power consumption

ST was a lead partner in developing the Cortex-M3 core and is now the first leading MCU supplier to introduce a product family based on the core.

Designed to deliver impressive levels of performance and energy efficiency while retaining all the benefits of working with the open, industry-standard ARM architecture and development environment, the STM32 is offered in two lines: the STM32F103 "Performance" line, with 72MHz clock frequency, provides best-in-class 32bit MCU performance, whereas the STM32F101 "Access" line, with 36MHz clock frequency, offers users of 16bit devices a significant increase in performance at the same 16bit price levels.

Both lines offer from 32 to 128Kbyte of embedded Flash memory but
