New STM32 F-2 Series
ST’s new leading-edge
STM32 F-2 microcontroller series combines ST’s advanced 90nm process
technology with the Company’s innovative Adaptive Real-Time memory
accelerator (ART Accelerator™) to unleash the Cortex-M3 core’s maximum
processing performance.
The STM32 F-2 MCUs achieve leading-edge performance of 150 Dhrystone MIPS when executing code from Flash at 120MHz, which is the maximum performance possible from the Cortex-M3 processor at this frequency.
The series also offers CoreMark-confirmed 200uA/MHz dynamic power consumption.
In addition to offering on-chip memory densities that are among the highest of any Cortex-M3 based MCUs available, the new series provides enhanced support for imaging, connectivity, security, audio and control applications.

In addition to offering on-chip memory densities that are among the highest of any Cortex-M3 based MCUs available, the new series provides enhanced support for imaging, connectivity, security, audio and control applications.
For many applications, the STM32 F-2 MCUs offer the perfect balance
between performance, dynamic power consumption and cost, which has been
confirmed with the news that more than 20 of ST’s customers are
currently ramping up manufacturing of new products enabled by this new
STM32 family.
“This series is a major addition to the STM32 platform and reinforces ST’s leadership in the market for Cortex-M3 MCUs,” added Buffa. “ST’s proprietary 90nm process and the development of the ART Accelerator enable perfectly optimized processor-memory interactions with a performance equivalent to zero wait states, taking the performance of the Cortex-M3 core to its natural limits.”
The addition of more than 30 new devices in the F-2 series brings the total number of STM32 microcontrollers to 180 pin- and software-compatible devices sharing a common pool of peripherals, and delivering the advanced performance, high efficiency and convenience of the industry-standard Cortex-M3 processor.
Production samples of the STM32 F-2 series are available now to OEM customers with widely availability in Q1 2011.
Prices for the STM32-F2 series begin from $3.18 for the STM32F205RBT6 with 128 Kbytes of Flash and 64 Kbytes RAM in the LQFP64 package, for orders of more than 10,000 units.
