STMicroelectronics : MCU with ARM Cortex-M7 core sets new performance standard – STM32F756NG / 32F746GDISCOVERY develpoment kit / STM32756G-EVAL board

The STM32F756NG microcontroller from STMicroelectronics draws on the high performance of the new ARM® Cortex®-M7 core to provide as much as two times the processing and DSP performance of previous generations of ARM Cortex-M MCUs.

The new MCU operates at up to 200MHz and uses a six-stage super-scalar pipeline and floating point unit to produce performance rated at up to 1,000 CoreMarks.

Architectural innovations by ST boost the MCU’s performance and ease of use. ST has included two independent mechanisms to produce zero wait-state performance from both internal and external memories: ST’s ART Accelerator™ for internal embedded Flash, and L1 cache for both execution and data access from internal and external memories.

Manufactured on ST’s robust 90nm CMOS process technology, the STM32F756NG produces its high performance without sacrificing power efficiency: in Run, Stop and Stand-by modes, it draws the same low current as the slower STM32 F4 series of MCUs. Power
usage is 120μA in Stop mode with all context and SRAM content saved, and 1.7μA in Stand-by mode Peripherals include an SDMMC interface, a flexible memory-control interface, and a camera interface for CMOS sensors.
