The new STM32 F7 microcontroller (MCU) series leverages the ARM Cortex-M7 core, just announced as ARM's newest and most powerful Cortex-M processor.

ST's STM32 F7 series leapfrogs the industry's previous high-performance 32-bit Cortex-M champ - ST's own STM32 F4 - in delivering up to twice as much processing and DSP performance that is accessible via a seamless upgrade path.

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 CoreMarks.

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(TM)) for internal embedded Flash and L1 cache for both execution and data access from internal and external memories.

Manufactured on ST's robust and production-proven 90nm embedded-non-volatile memory CMOS process technology[, 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.

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.

Features:

－ An AXI and Multi-AHB (Advanced High-performance Bus) matrix with dual general-purpose DMA (Direct Memory Access) controllers and dedicated DMA controllers for Ethernet, USB OTG HS (Universal Serial Bus On-the-Go High Speed), and hardware acceleration of graphics via ST's Chrom-ART Accelerator(TM);

－ Available in 512kB and 1MByte embedded Flash to support applications that require large storage for code;

－ Large SRAM with scattered architecture

－ STM32 F7 peripherals also include an independent clock domain to enable system-clock-speed changes without impacting communication speed;

－ Flexible external memory controller with up to 32-bit data bus: SRAM,PSRAM,SDRAM/LPSDR, SDRAM, NOR/NAND memories;

－ Dual Quad SPI interface for cost-effective memory extension even on lo- pin-count packages;

－ Builds on the existing STM32 F4 series instruction set, delivering exclusively single-cycle Multiply and Accumulate (MAC) instructions and offering Single-Instruction Multiple Data (SIMD) instructions that work on 8- and 16-bit quantities packed into a 32-bit word.
