Dual-core STM32H7 officially put into production samples are now available

Previously, there was a dual-core STM32H7 message on the Internet. Today, ST official officially announced that dual-core H7 has been put into production. 1. In 2016, STM32H7 became the most powerful Cortex-M7 in the market and broke the 2000 points of Coremark. In the next few years, ST continues to optimize its manufacturing processes to improve performance, and customize the architecture according to different industries. For example, the new STM32H742 deletes the TFT LCD controller and JPEG codec unit, while also falling RAM to 692 KB to ensure that the system does not require a display of a better value proposition. Similarly, ST last year's STM32H7 value line, Flash is much less, so it is necessary to external QuadSPI designers for graphic intensive applications do not need to pay the embedded storage they never use. Today, the STM32H750 is the first commercial value line MCU in the STM32H7 series. 2. ST has released a new STM32H7 microcontroller today to make this series of MCUs more powerful, flexible and easy to use. Running speed: Cortex-M7 480 MHz and Cortex-M4 240 MHz. Coremark runs: 3220 points. 3. STM32H7 series of most powerful new features: additional Cortex-M4 The most obvious performance improvement comes from an increase of a Cortex-M4 kernel to increase the Coremark score of 800 points. This dual-core architecture is very flexible due to the adoption of a delicate design. For example, the system can be started on either core, and they respectively exist in a separate power domain significantly optimized energy consumption. For example, when the application does not require Cortex-M7, developers can turn off their power domains without any impact on other cores. Therefore, the dynamic power consumption of the new dual-core model is much better than STM32F7. Code Migration: Companies that have written applications in Cortex-M7 or Cortex-M4 STM32 can reuse some of their code and build on it. 4. New Features of Dual-core STM32H7: Mipi-DSI, 16-bit ADC and FD-CAN. The MIPI display serial interface (MIPI-DSI) is introduced in STM32H7. STM32H7X5 and STM32HX7 can more flexibly use three 16-bit model converters on the die (up to 3.6 megabytes per second). Two FD-CAN interfaces and its Ethernet controllers also provide an excellent advantage for industrial applications. 5. New features of STM32H7: Dual-Bank Flash and Root Security Services. Dual flash memory divides the storage capacity into two parts, the first part is used for the application, but can load the new firmware in the second part, then perform hot-swap to run the system on the latter, so that major updates are achieved without interruption Any stop will appear. Another feature is that root security services (RSS), using the form of bootloader, engineers can use it to securely install firmware. Read more
