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. […]

Year 2019 in Review – Top 10 Posts and Stats

2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the […]

UL IoT Security Rating System Ranks IoT Devices Security from Bronze to Diamond

Underwriters Labs (UL) is better known for its electrical safety certification programs, but in 2016, the company introduced three UL 2900 IoT security standards that defined requirements of software cybersecurity for network-connectable products. Four years later, you may not have heard many products adhering to UL 2900, and Laurens van Oijen, IoT security solution leader at UL, recognizes that ” the UL 2900 set the bar too high for most consumer electronics/IoT companies” according to a report on CE Pro. So instead the company has launched the UL IoT Security Rating System last May with 5 levels of “security capabilities” ranking IoT devices and products with either Bronze, Silver, Gold, Platinum, or Diamond. Those certifications are aimed to help both manufacturers and developers to improve the security of their solutions, and help consumers make better purchase decisions by knowing the level of security of IoT products by just looking at […]

Some Interesting Talks from FOSDEM 2020 Schedule

We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]

Banana Pi BPI-F2S Industrial SBC Launched for $58 with Linux 4.19 based Debian or Fedora OS

Last month we covered Banana Pi BPI-F2S single board computer (SBC) for industrial, IoT, and smart audio application that was powered by the intriguing SunPlus SP7021 “Plus1” processor featuring four Cortex-A7 cores, one ARM9 ARM9 real-time core, and one 8051 I/O controller core, as well as up to 512MB built-in DDR3 RAM. At the time, the board was not available, and we had limited information about software support, except the company would provide a Yocto-based Linux distribution. The good news is that you can now buy Banana Pi BPI-F2S industrial SBC on Aliexpress for $58 and Taobao for 390 RMB, and the company released source code and OS images for the board. Here’s a reminder of Banana Pi BPI-F2S specifications: SoC – Sunplus SP7021 “Plus1” with a quad-core Cortex-A7 processor @ 1.0 GHz, one Arm A926 microprocessor, an 8051 core to handle I/Os, and 128MB or 512MB DDR3 DRAM. Storage […]

GreenWaves GAP9 IoT Application Processor Enables AI on Coin-cell Powered Devices

GreenWaves Technologies GAP8 multi-core RISC-V microcontroller was introduced last year for artificial intelligence (AI) at the edge at ultra-low power consumption. GAP8 AIoT SoC was shown to perform inference at 3.7mA against 60mA for the same workload on STM32F7 Arm Cortex-M7 MCU. The company has now expanded its GAP IoT application processor family with GAP9 that delivers five times lower power consumption compared to GAP8 microcontroller while enabling inference on neural networks 10 times larger. Greenwaves GAP9 will bring machine learning and signal processing capabilities to (coin cell) battery operated or energy harvesting devices such as IoT sensors in consumer and industrial markets, wearables, smart building, smart farming and so on. GAP9 is said to combine architectural enhancements with Global Foundries 22nm FDX process to achieve a peak cluster memory bandwidth of 41.6 GB/sec and up to 50 GOPS compute power while consuming only 50mW. The increased memory bandwidth (20x […]

iCommSemi SV6166F is a Low-Power WiFi SoC for IoT and Embedded Systems

The other day I wrote about Sonoff Micro WiFi USB Smart adapter featuring a CKW04 WiFi chip, but one person suspected it may be based on iCommSemi SV6166F chip with very similar features and the same 6x6mm form factor. It’s still unclear whether that’s the chip used in Sonoff Micro, but AFAICR I never heard about iCommSemi previously, so let’s have a look at SV6166F in particular. The SV6166F is a low-power single-chip device designed for integration into the Internet of Thing and embedded systems with support for 802.11b/g/n WiFi at 2.4 GHz. SV6166F highlights: MCU – Andes Technology N10 processor with ILM/DLM and I-cache.
