STM32H7 ARM Cortex-M7 by STMicroelectronics

Posted by stromium – November 26, 2016

STMicroelectronics has on display their ARM Cortex-M7. The H7 is the successor to the F7. The H7 uses 40nm process node over 90nm for the F7, allowing for a higher 400MHz clock speed (compared to 200MHz). The demo setup is running a fractal program and has UARC, Ethernet and several display outputs. The faster speeds allows for graphics processing that earlier needed Cortex-A cores, with audio applications possible as well.

ARM Cortex-M7 in STM32 F7 STMicroelectronics, IS2T brings MicroEJ Java apps store for embedded market

Posted by Charbax – February 27, 2015

STMicroelectronics launches STM32 F7 series of very high performance Microcontroller Units based on the ARM Cortex-M7 core. The STM32 F7 devices are the world’s first ARM Cortex-M7 based 32-bit microcontrollers, improving on the benchmark performance. Taking advantage of ST’s ART Accelerator as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory: 1000 CoreMark/428 DMIPS at 200 MHz fCPU.

Demonstrated running on the STM32 F7, IS2T MicroEJ SDK enables embedded Java development for any MCU and MPU, from the smallest ARM Cortex-M0+ to the newest Cortex-M7 and beyond. The embedded Java platform includes IS2T Java Virtual Machine (footprint: 28KB of RAM, 1.5KB of RAM) and IS2T libraries for IoT, GUI and communication applications. Boot time to first line of Java main is 2ms on a Cortex-M4@120MHz.

IoT solutions includes TPC/IP, Wifi, MQTT, Websockets, HTTP, JSON, XML, COAP... protocols. GUI solutions includes a full set of widgets, drawing, motions, anti-aliased... libraries - typical animations at 60FPS with less than 10% CPU load. Full Java applications run on MCU starting from 256KB of flash.

The MicroEJ demo running on STM32F7 device shows the Waddapps store connection, an online store of embedded applications that can be downloaded to the STM32F7 through any link (e.g. ethernet, Wifi, Bluetooth). Apps are downloaded, installed, started, stopped, uninstalled without reset - same as smartphone users would typically do with an Apps Store.
