Semiconductors lead times in March 2021

As we previously mentioned previously there is a serious chip shortage that will lead to supply issues and higher prices for single board computers and other electronics products. A few days ago, Hardkernel had o increase the price for ODROID boards using DDR4 memory with increases of $3 to $4 for ODROID-N2+, ODROID-C4, and ODROID-HC4 boards. But besides price increase, some semiconductors will not be available at any price with extended periods as lead times of up to 52 weeks have been reported as shown in the table below, obtained from a trusted, anonymous source, which I have translated from Chinese. Every manufacturer is impacted, but items highlighted in red are severely impacted. Since include processors from Qualcomm, STMicroelectronics, and NXP, as well as Broadcom wireless chips which are found in nearly every SBC with WiFi or Bluetooth through Ampak modules. Here’s the source image in Chinese for reference. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time […]

MikroElektronika Launches Fusion for ARM & EasyPic MCU Development Boards

fusion for arm

During Embedded World 2020 (EW2020), some companies withdrew their presence, while some were at the event. MikroElektronika presented several new boards and among them Fusion for ARM v8 and EasyPic v8 development boards. While we already wrote about Fusion fo TIVA, we haven’t covered any EasyPic board yet. Development boards from MikroElektronika allow rapid prototyping in the most efficient and effortless way. Fusion for ARM v8 Fusion for ARM v8 belongs to the Fusion family of development boards. It has integrated the world’s first embedded debugger/programmer over WiFi, while the CODEGRIP WiFi license is available as an add-on feature. The board is designed to be used in almost every environment retaining full debugging and programming access. The CODEGRIP currently supports more than 1600 microcontrollers from different vendors. The Fusion board integrates a new MCU card standard. It is a low profile standard where sockets consist of two connectors (male/female) which prevents the wrong insertion. The MCU card has standardized dimensions […]

Arm Techcon 2019 Schedule – Machine Learning, Security, Containers, and More

Arm Techcon 2019

Arm TechCon will take place on October 8-10, 2019 at San Jose Convention Center to showcase new solutions from Arm and third-parties, and the company has now published the agenda/schedule for the event. There are many sessions and even if you’re not going to happen it’s always useful to checkout what will be discussed to learn more about what’s going on currently and what will be the focus in the near future for Arm development. Several sessions normally occur at the same time, so as usual I’ll make my own virtual schedule with the ones I find most relevant. Tuesday, October 8  09:00 – 09:50 – Open Source ML is rapidly advancing. How can you benefit? by Markus Levy, Director of AI and Machine Learning Technologies, NXP Over the last two years and still continuing, machine learning applications have benefited tremendously from the growing number of open source frameworks, tools, and libraries to support edge inferencing. These include CMSIS-NN, ARM […]

Arduino Compatible ASME TIGER Board Supports Thread on NXP Kinetis KW41Z WiSoC

The new Arrow ASME Tiger board is the latest addition to the ASME line up, with an eye towards IoT hardware prototyping. The board carries two MCUs for different types of development depending on the operators need. The board is Thread and WiFi ready, and the Tiger is also Arduino compatible. The MCU’s are as follows: The ATSAMD21J18A-64 Ultra-low-power microcontroller using the 32-bit ARM Cortex-M0+ processor. The WiSoC is the KW41Z which is an ultra-low-power, highly integrated single-chip device that enables Bluetooth® low energy (BLE) v4.2 and IEEE® 802.15.4 RF connectivity for portable, extremely low-power embedded systems. The working unit is for very low power applications. The integrated balun reduces system cost and board area, and the sensors are plentiful and easy to access. You’ll find a user guide (PDF), as well a bootloader and sample code on Github. Specifications for the SMART SAMD21 Memory 256KB in-system self-programmable Flash 8KB Flash Read-While-Write section 32KB SRAM Main Memory 8KB SRAM Low […]

OpenISA VEGAboard Combines RISC-V and ARM Cortex-M Cores


OpenISA has launched an Arduino compatible RISC-V development called VEGAboard that features RV32M1 wireless microcontroller with a RISC-V RI5CY core, a RISC-V ZERO-RISCY core as well as Arm Cortex-M4F and Cortex-M0 cores, and a radio operating in the 2.36 GHz to 2.48 GHz range. An external NXP Kinetis K26 Arm Cortex-M4 MCU is added to the board for OpenSDA (Open-Standard Serial and Debug Adapter) debugging over a single USB cable.

NXP Unveils A71CH Secure Element Chip for Secure Peer-to-Peer or Cloud Connections

The industry clearly has an issue at hand with the security of the Internet of Things, and the problem is complex as some devices are easily accessible due to bad configuration (e.g. default username/password), while others may have security flaws at various levels of the software stack from the low level bootloaders to the operating systems, and applications. Nowadays, devices also need to be upgradeable, and communicate with the cloud, and that introduces other attack vectors in case malignant firmware is installed instead, or a man-in-the-middle attack occurs. While some people may claim security can be achieved by software only, we are seeing security evolving towards combined software and hardware solutions, for example with Arm Trustzone built into SoCs, but some companies are also introducing Secure Element chip, which Samsung has already done and integrated into their Artik  modules to secure data from the hardware to the cloud. NXP has now also launched their own A71CH Secure Element (SE), described […]
