STMicro adds Dual-core Cortex-M7/M4 Microcontrollers to STM32H7 Family

STM32H747I-DISCO

STM32H7 is the high-performance family of STMicroelectronics Arm Cortex-M7 microcontroller. So far all STM32H7 MCUs had a single core, but the company has now added dual-core devices (STM32H74x/75x) comprised of an Arm Cortex-M7 core clocked at up to 480 MHz and a Cortex-M4 core clocked at 240MHz. In some way, this part is the little brother of STM32MP1 Arm Cortex-A7 + Cortex-M4 processor, as the new dual-core MCU also targets current products upgrade with the Arm Cortex-M4 core running legacy code, and the more powerful Cortex-M7 aimed at new features such as more sophisticated graphical interfaces, or offloading intensive workloads such as neural networks, checksums, DSP filtering, or audio codecs. Highlights of the new STM32H7 dual-core microcontrollers: Cores Arm Cortex-M7 at 480 MHz Arm Cortex-M4 at 240 MHz 3224 CoreMark / 1327 DMIPS Up to 2MByte Flash and 1Mbyte SRAM on-chip Dual-Bank Flash for seamless firmware updates “New” features MIPI display serial interface (MIPI-DSI) in STM32H7x7 3x 16-bit ADC up …

Pyboard D-series Wireless Micropython Boards Launched for $56 and Up

buy pyboard d-series

We’ve already mentioned the latest Pyboard D-series board at the beginning of February after it was introduced at FOSDEM 2019. The board comes with a powerful STM32F7 Arm Cortex-M7 microcontroller, as well as a WiFi and Bluetooth wireless module. The news is that the board has now launched for £43.80 in.c VAT ($56) and up. A better price comparison with other boards is normally achieved by comparing the ex. VAT price of £36.50 or about $48. That may still feel a bit pricey to some, but there was enough interest to snatch all available “PYBD-SF2-W4F2” boards, and this specific board is out of stock at the time of writing. However, there are multiple variants of the board and PYBD-SF3-W4F2 is still in stock for £58.20 inc. VAT (~$76.5). We’ve now got the full Pyboard D-series “PYBD-SF2-W4F2” specifications: MCU – STMicro STM32F722IEK Arm Cortex M7 microcontroller at 216 MHz with 256KB RAM, 512KB flash, single precision FPU Storage micro SD card …
