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

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 […]

ReButton WiFi Button Features MXCHIP EMW3166 Module

We’ve previously covered WiFi buttons based on ESP8266 processor, but Seeed Studio has just launched ReButton “developer device” that serves the same purpose but features STM32 based MXCHIP EMW3166 WiFi module instead, exposes one I2C grove connector, and is preloaded with sample firmware that triggers Azure IoT Central or Azure IoT Hub. ReButton hardware specifications: MCU module – MXCHIP EMW3166 module including STM32F412 Arm Cortex M4F MCU @ 100 MHz with 256KB SRAM, 1MB+2MB SPI Flash, and Cypress BCM43362 WiFi chip Input – 1x Push button Output – 1x RGB LED Extension – 1x I2C Grove connector (3.3V I/O) Debugging – 1x SWD pads, 1x UART for debugging Misc – 1x Jumper switch Power supply 2x AAA Alkaline batteries (LR03) Internal supply voltage – 3.3V Dimensions – 70 x 70 x 25mm The ReButton comes preloaded with an Arduino sketch that handle key presses and send a trigger to Azure […]

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

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 […]

Octavo Systems Unveils OSD32MP15x STM32MP1 SiP (System-in-Package)

STMicro STM32MP1 is one of the most interesting microprocessor recently announced, as it should allow a relatively easy upgrade path for projects based on the traditional STM32 Cortex-M4 microcontrollers, thanks to backward compatibility, and the extra one or two Arm Cortex-A7 cores enabling Linux support. We’ve already seen several upcoming evaluation and development boards based on STM32MP157 processor including STMicro’s own discovery kits and evaluation platform, as well as Arrow Electronics Avenger96 board fitted with a tiny 29x29mm SoM. But I suspect we could see even more compact designs soon, as Octavo Systems has now unveiled OSD32MP15x system-in-package with STM32MP15x MPU, up to 1GB RAM, 4K EEPROM, STPMIC1 power management IC, two oscillators, and over 100 passive components all brought together into a 18x18mm package. Octavo Systems OSD32MP15x system-in-package main components and specifications: MPU (MicroProcessor Unit) – STMicroelectronics STM32MP15x with Dual Arm Cortex-A7 @ 650MHz, Arm Cortex-M4 real-time core @ […]
