New series demonstrates time-to-market innovation, embedding a full set of advanced features around a new core to deliver smartest STM32 MCUs ever
Geneva / 24 Sep 2014
Headlining the industry’s most successful family of Cortex M-core-based microcontrollers, the new STM32 F7 MCU series operates at frequencies up to 200 MHz and uses a 6-stage superscalar pipeline and Floating Point Unit (FPU) to produce up to 1000 CoreMarks1. Architectural innovations surrounding the MCU boost performance and ease of use: ST has included two independent mechanisms to reach 0-wait-state performance from both internal and external memories: using ST’s Adaptive Real-Time (ART Accelerator™) for internal embedded Flash and L1 cache for both execution and data access from internal and external memories.
“ARM and ST have a long-standing and extensive business relationship, and it is exciting to see this extended to include MCUs based on the latest ARM Cortex-M7 processor,” said Noel Hurley, general manager, CPU group, ARM. “This partnership brings the benefits of the broadest ecosystem to a new set of performance- and reliability-demanding embedded applications.”
“ST has earned its place as the long-time leading supplier of Cortex-M MCUs by working closely with ARM as a lead partner and with our customers to ensure their time-to-market success,” said Daniel Colonna, STMicroelectronics Microcontroller Marketing Director. “The strength of our development ecosystem, the breadth of our MCU, sensor, power, and communications portfolios, and the technical support we deliver to customers makes the STM32 F7 the seamlessly accessible natural extension to top our industry-leading portfolio. The new level of internal- and external-memory performance gives developers new possibilities for innovation, as they no longer need to optimize their code for performance and memory.”
Manufactured on ST’s robust and production-proven 90nm embedded-non-volatile memory CMOS process technology2, the STM32 F7 series impressively demonstrates ST’s commitment to accelerate its own and customer innovation to meet time-to-market demands. At the same time, the advanced, future-proof architecture offers significant headroom to deliver far greater MCU performance as the Company moves to more advanced process geometries. The high-performance STM32F756NG MCU is sampling now to lead customers now and will be demonstrated at ST’s stand during ARM TechCon in Santa Clara, Oct 1-3, 2014.
Further Technical Information:
Surprisingly, the higher performance of the STM32 F7 has not impacted power efficiency. Despite greater functionality, the new series’ Run mode and low-power modes (STOP, Standby, and VBAT) consume current at the same low levels as the STM32 F4: 7 CoreMarks/mW in Run mode and, for low-power modes, down to 120 uA typical in STOP mode with all context and SRAM content saved, and 1.7uA typical in STANDBY mode and 0.1uA typical in VBAT mode.
In addition to ST’s ART Accelerator™ and 4Kbytes Instruction and Data caches, the STM32 F7 includes smart and flexible system architecture:
