STM32H7: the 1st Cortex-M7 with Advanced 40nm Flash Technology, the 1st to Run at 400MHz

Question asked by Amel N Employee on Oct 20, 2016

STM delivers record performance and advanced secure services for the IoT with the new STM32 high-perf MCU series STM32H7: Cortex-M7 running at 400MHz embedding the highest SRAM memory (1Mbytes) and up to 2MB Flash memory.


The first device in the new series -STM32H743- frees developers from the resource constraints that typically complicate high-end embedded development.
It interacts efficiently with either internal or external memory, thanks to its unique L1 cache and TCM memory.
It draws on a pool of 35 communication peripherals that support advanced protocols and standards such as CAN FD, SDCARD (4.1), SDIO (4.0), and MMC (5.0).
There are also 11 enhanced analog functions including low-power 14-bit ADCs running at up to 2Msample/s, 12-bit DACs and op-amps, as well as 22 timers, which include a high-resolution timer running at 400MHz.
These important enhancements enable the STM32H743 to set new performance records of 856DMIPS[1] and an EEMBC® CoreMark® [2] score of 2010.

As well as dramatically increasing the performance and resources, the STM32H7 MCU series also incorporates STM32 Dynamic EfficiencyTM energy-saving techniques that help the new devices consume half the dynamic power of their predecessors in the STM32F7 series thanks to:
- Dynamic Voltage Scaling that adjusts power consumption according to performance demands
- Batch-Acquisition Mode that captures data directly into memory without waking the core from energy-saving mode.
- Multiple Memory Domains that support Dynamic Efficiency energy management.

Evaluation boards, Nucleo kits and Discovery kits will all be offered for the STM32H7 series, along with STM32Cube embedded software, and will be supported by ARM mbed OS to take advantage of advanced software
stacks available to all developers.

The STM32H743 and further STM32H7 product lines will be in full production in Q2 2017.
