The ARMŽ Cortex-M3-based STM32 F2 series uses ST’s advanced 90 nm NVM process technology with the innovative adaptive real-time memory accelerator (ART Accelerator™) and multi-layer bus matrix. This offers an unprecedented trade-off in price and performance.
New STM32 F2 series offers 30 new devices; delivers 150DMIPS for high-performance power-sensitive applications.
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
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.
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
“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.
