Arduino have launched an upgrade to their 8-bit Arduino UNO R3 board with the Arduino UNO R4 featuring a 48 MHz Renesas RA4M1 Arm Cortex-M4F 32-bit microcontroller, and an optional ESP32-S3 module for WiFi 4 and Bluetooth 5.0 connectivity. The new Arduino UNO R4 offered improved performance and greater resources since the MCU is clocked three times faster than the 8bit AVR MCU found in the UNO R3, the board gets sixteen times more RAM (32KB vs 2KB to 32kB) and eight times more flash memory (256KB vs 32kB). The USB Type-B device port has been upgraded to a more modern USB Type-C port and the UNO R4 can take up to 24V supply voltage. Arduino UNO R4 (preliminary) specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash. 8KB dataflash Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core […]
Renesas introduces 100 MHz RA4E2 and 200 MHz RA6E2 Arm Cortex-M33 MCUs for wearables, sensors, appliances
Renesas Electronics has added two new groups to its 32-bit RA family of microcontrollers (MCUs) with the 100 MHz RA4E2 and 200 MHz RA6E2 Arm Cortex-M33 microcontrollers designed for “high-performance applications” in small packages such as sensing, gaming, wearables, and appliances. The new microcontrollers are equipped with 40 KB SRAM, 128 KB or 256 KB flash, and integrate various on-chip interfaces such as CAN FD, USB, QSPI, SSI, and I3C interfaces to offer an easy upgrade path for products based on other members of the Renesas RA Family. Renesas RA4E2 MCU group Both the RA4E2 and the RA6E2 are the most cost-effective microcontroller groups of the RA family with integrated CAN FD, with the RA4E2 group especially well-suited to cost-sensitive applications and other systems requiring relatively high performance, low power consumption, and/or small package size. RA4E2 key features: CPU – Arm Cortex-M33 core with TrustZone @ up to 100 MHz […]

Aspinity AB2 AML100 Arduino Shield supports ultra-low-power analog machine learning
Aspinity AB2 AML100 is an Arduino Shield based on the company’s AML100 analog machine learning processor that reduces power consumption by 95 percent compared to equivalent digital ML processors, and the shield works with Renesas Quick-Connect IoT platform or other development platforms with Arduino Uno Rev3 headers. The AML100 analog machine learning processor is said to consume just 15µA for sensor interfacing, signal processing, and decision-making and operates completely within the analog domain offloading most of the work from the microcontroller side that can stay its lowest power state until an event/anomaly is detected. Aspinity AB2 AML100 Arduino Shield specifications: ML chip – Aspinity AML100 analog machine learning chip Software programmable analogML core with an array of configurable analog blocks (CABs) with non-volatile memory and analog signal processing Processes natively analog data Near-zero power for inference and events detection Consumes <20µA when always-sensing Reduces analog data by 100x Supports up […]
Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures
Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]
Renesas RL78/G15 8-bit MCU is offered in a 3x3mm package
Renesas Electronics RL78/G15 is an entry-level 8-bit microcontroller with 1 KB of SRAM, 4 or 8KB of code flash memory, and offered in package sizes ranging from 8 to 20 pins, down to an 8-pin device measuring just 3×3 mm. STMicro has just unveiled the STM32C0 32-bit microcontroller claiming “your next 8-bit MCU is a 32-bit” with packages from 8- to 48-pins and packages as small as 1.70 x 1.42 mm and 3x3mm, and a price similar to other 8-bit industrial microcontrollers. To that, I say “not so fast STMicro!”, as Renesas has just launched the 16 MHz RL78/G15 8-bit microcontroller family with many of the same features and target use cases as the STMC32C011 sub-family. Renesas RL78/G15 key features and specifications: CPU core – Renesas RL78 8-bit core @ up to 16 MHz Memory – 1NS SRAM, Storage – 4 to 8KB program flash, 1KB data flash Peripheral I/F […]
MistySoM Renesas RZ/G2L or RZ/V2L SoM and devkit goes for $112 and up
We’ve previously written about several system-on-modules and SBCs based on Renesas RZ/G2L or RZ/V2L Cortex-A55/M33 processors such as Geniatech “AHAURA” RS-G2L100 and “AKITIO” RS-V2L100 single board computers, Forlinx FET-G2LD-C system-on-module, and SolidRun RZ/G2LC SOM and devkit. But most of those are hard to buy, and you need to contact the company, discuss your project, etc… before purchase, except for the SolidRun Renesas RZ/G2LC Evaluation Kit going for $249. Another option is the MistyWest MistySOM module offered for $112 and up on GroupGets with either Renesas RZ/G2L or RZ/V2L processor, as well as an optional carrier board. MistySOM system-on-module MistySOM-G2L (aka MW-G2L) and MistySOM-V2L (aka MW-V2L) specifications: SoC – Renesas RZ/G2L or RZ/V2L with dual-core Cortex-A55 processor @ 1.2 GHz, Arm Cortex-M33 core @ up to 200 MHz, Arm Mali-G31 GPU, and DRP-AI vision accelerator (RZ/V2L only) System Memory – 2GB LPDDR4/DDR4 Storage – 32GB eMMC flash 2x 120-pin high-speed mezzanine […]
Linux 6.1 LTS release – Main changes, Arm, RISC-V and MIPS architectures
Linus Torvalds announced the release of Linux 6.1, likely to be an LTS kernel, last Sunday: So here we are, a week late, but last week was nice and slow, and I’m much happier about the state of 6.1 than I was a couple of weeks ago when things didn’t seem to be slowing down. Of course, that means that now we have the merge window from hell, just before the holidays, with me having some pre-holiday travel coming up too. So while delaying things for a week was the right thing to do, it does make the timing for the 6.2 merge window awkward. That said, I’m happy to report that people seem to have taken that to heart, and I already have two dozen pull requests pending for tomorrow in my inbox. And hopefully I’ll get another batch overnight, so that I can try to really get as […]
