ARM Cortex MCUs
30 March 2011
DSP, Micros & Memory
STMicroelectronics announced that the roadmap for its STM32 family of 32-bit MCUs based on ARM Cortex-M processor cores is to include new devices centred on the Cortex-M4 and the Cortex-M0 cores from ARM. In addition, the company announced availability of its new STM32 F-2 series MCUs based on the Cortex-M3 core.
The Cortex-M4 is an upwardly compatible version of the Cortex-M3, offering DSP instructions and a floating point unit (FPU), while the Cortex-M0-based devices will target costsensitive applications. All future STM32 Cortex-M4 and -M0 based MCUs will remain fully pin- and software-compatible with each other and the STM32 Cortex-M3 devices. In addition, they will benefit from the same tool and software ecosystem, allowing seamless moves within the full STM32 product range.
ST’s new STM32 F-2 microcontroller series combines 90 nm process technology with the company’s adaptive real-time memory accelerator (ART Accelerator) to exploit the Cortex-M3 core’s maximum processing performance. The MCUs achieve performance of 150 Dhrystone MIPS when executing code from Flash at 120 MHz. The series also offers CoreMark-confirmed 188 μA/MHz dynamic power consumption when executing from Flash, equivalent to drawing 22,5 mA at 120 MHz. In addition to offering high on-chip memory densities, the new series provides enhanced support for imaging, connectivity, security, audio and control applications.
