Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

SONOFF iPlug S60 – A $10.9 compact WiFi smart socket with built-in energy monitoring function

SONOFF iPlug S60 is a compact ESP32-C3-based WiFi smart socket with built-in energy monitoring support and available with either Type E/F or Type G prongs for respectively European and British markets, as well as other countries using those types of sockets. ITEAD has manufactured home automation devices that measure power consumption for years, such as the SONOFF POW switch directly connected to the mains or the SONOFF S31 smart socket, but those are/were much larger devices, and the new SONOFF iPlus S60 is fairly small and barely larger than some other smart sockets that lack an energy monitoring function, whiling handling up to 16A or 4,000W at 220-250V. SONOFF iPlug specifications: Wireless MCU – ESP32-C3 RISC-V microcontroller with 2.4GHz WiFi 4 802.11b/g/n S60TPG Plug type – Type G (UK) Input – 250V, 50/60Hz, 13A max Max load – 3,250 Watts Dimensions – 58 x 58 x 42 mm Weight – […]

Renesas’ first 32-bit RISC-V CPU core delivers up to 3.27 CoreMark/MHz

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on open-standard instruction set architecture (ISA).

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on the open-standard instruction set architecture (ISA). This CPU core is compatible with Renesas’ e2 studio IDE and supports other third-party IDEs for RISC-V MCUs. According to Renesas, the CPU achieved a remarkable 3.27 CoreMark/MHz performance outperforming similar RISC-V architectures in this category. RISC-V, an open ISA, is rapidly gaining popularity in the semiconductor industry. Many MCU providers have formed joint investment alliances to expedite their RISC-V product development. Previously, Renesas released two CPUs developed by Andes Technology Corp: the R9A02G020, an ASSP EASY MCU for Motor Control, and the R9A06G150, an ASSP EASY MCU for Voice HMI, both based on RISC-V. Additionally, they have introduced the RZ/Five, a Linux-capable 64-bit RISC-V microprocessor family, and RH850/U2B, an automotive System on Chip (SoC). However, with the release of their new CPU, Renesas independently enters the RISC-V market, highlighting their […]

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running. But the event will have two periods: Nov 20-22 PT – Warm Up event where users can find and add items to the cart before purchasing during the […]
