STMicro launches cheaper STM32WB30 and STM32WB35 Bluetooth LE & Zigbee MCUs

STMicro introduced the first wireless STM32 microcontrollers in 2018 with STM32WB Cortex-M4/M0+ MCU family equipped with Bluetooth 5.0 and 802.15.4 radios, and they followed earlier this year with STM32WL Cortex-M LoRa SoC. The company has not just announced yet another wireless STM32 family but instead added the more affordable STM32WB35 and STM32WB30 chips that can be obtained for under $2 in quantities. The new STM32WB microcontroller enabled a low BOM cost thanks to their memory configuration. Specifically, STM32W30 comes with 256KB flash while STM32W35 features 512 KB flash, and both offer 96 KB of RAM. This compares to STM32WB55 will up to 1MB flash and 256KB of RAM. Apart from the lower memory and flash capacity, the new wireless MCUs have basically the same features as other members of the STM32WB family with 16-bit ADC, quad-SPI interface (STM32WB35 only), as well as Bluetooth Low Energy 5.0, Zigbee 3.0, and OpenThread […]

New STM32H7 Cortex-M7 MCUs Clock at 550 MHz, Feature Octal SPI Flash and Ethernet Interfaces

STMicro launched STM32H7 single-core Cortex-M7 microcontroller family a while ago, followed by some dual-core Cortex-M7/M4 models, with most clocked up to 480 MHz. The company has now announced five faster parts clocked at up to 550 MHz with STM32H723, STM32H733, STM32H725, STM32H735, and STM32H730 which STMicro claims is “the fastest core speed in the market among MCUs that integrate Flash storage on-chip to run deeply embedded applications”. The embedded flash storage is important, as you may now NXP i.MX RT1170 Cortex-M7/M4 crossover processor can reach up to 1 GHz but does not include flash storage. Key differences in STM32H7 550 Mhz MCUs We’ve highlighted the five new microcontrollers in the table above, and beside the higher 550 MHz frequency delivering 2778 CoreMark and 1177 DMIPS, we can see those are the only parts that support both OctoSPI flash and Ethernet, and all five parts are designed for HMI applications with […]

STMicroelectronics Introduces Zigbee 3.0 to the STM32WB55 microcontrollers

STMicroelectronics has added Zigbee 3.0 support to its STM32WB55 wireless microcontroller family using the Zigbee PRO protocol stack. The STM32 Wireless MCU (STM32WB55) was launched last year with a dual-core Arm Cortex-M4 CPU and Cortex M0+ core, as well as  Bluetooth 5 and 802.15.4 radios. STMicro is hoping to expand the applications of the STM32WB into areas like home automation as Zigbee 3.0 is making brands choose Zigbee for their smart-home connectivity solution, smart-lighting, smart-building, mesh IoT connectivity, and many more. The STM32WB55 microcontrollers already provide support for Thread and Bluetooth 5.0 and the inclusion of the Zigbee connectivity will take this to the next level. The STM32WB55 Zigbee 3.0 software includes support for the Exegin Zigbee PRO protocol stack which is available for free. To ease development and deployment, STM32WB Zigbee solution supports 46 Zigbee 3.0 clusters and a further 21 clusters support legacy products and with the Zigbee 3.0 […]

Arrow Embedded To Go Free Online Conference, and 3,000 Development Boards Giveaway

With the coronavirus outbreak on-going, many events are either canceled or moving online. Arrow Electronics has now announced what appears to be a completely new online event. Embedded To Go virtual technology exhibition for embedded systems will take place on April 1-3, 2020, and offer technical presentations, information on newly launched technology, and access to Arrow’s sales and engineering teams. The event will entirely free to attend, and you can register online today with a company’s email address. The event will start in about 10 days by so far the virtual “booth map”, “supplier guide” and “lecture area” are inaccessible. We only know what the event should consist of thanks to an article on EENew Embedded: Technical presentation webinars will be hosted by leading suppliers covering AI, IoT and Edge computing, precision measurement, high-performance computing, intelligent condition-based monitoring, and other technological subjects. Information will also be available in the form […]

STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. […]
