Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.19

Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected – just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there’s always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow – thank you to all the early maintainers. And as people have mostly figured out, I’m getting to the point where I’m being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to […]

Microchip IC32 BZ6 single chip wireless MCU

Microchip has recently introduced the PIC32-BZ6 family of single-chip, multiprotocol wireless MCUs, also available as RF-certified modules, and designed for smart home, industrial automation, and automotive applications. The module supports Bluetooth LE 6.0, IEEE 802.15.4-based Thread and Matter, and proprietary mesh protocols. For wired connectivity, there are two CAN-FD ports, a 10/100 Mbps Ethernet MAC, and a USB 2.0 full-speed transceiver. Other features include CVD-based touch sensing and motor control interfaces for interactive and real-time applications. As a secure MCU, the PIC32-BZ6 integrates a hardware-based security engine, a secure boot ROM, and encryption accelerators, along with OTA update capability for long-term device management. The microcontroller offers up to 54 GPIO pins, multiple pin and package options (up to 132-pin VQFN), and automotive-grade variants rated for -40°C to +125°C operation. Microchip PIC32-BZ6 specifications: MCU Core – 128 MHz Arm Cortex-M4F with FPU and DSP extensions Memory 512 KB multi-port SRAM (with […]

Linux 6.16 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.16 release arm linux mips

Linus Torvalds has just announced the release of Linux 6.16 on LKML: It’s Sunday afternoon, and the release cycle has come to an end. Last week was nice and calm, and there were no big show-stopper surprises to keep us from the regular schedule, so I’ve tagged and pushed out 6.16 as planned. It’s worth noting that the upcoming merge window for 6.17 is going to be slightly chaotic for me: I have multiple family events this August (a wedding and a big birthday), and with said family being spread not only across the US, but in Finland too, I’m spending about half the month traveling. That means that I will try very hard to get most of the merge window done the first week before my travels start, and I already ended upgiving a heads-up on that to the people who tend to send me the most pull requests.

Microchip launches low-cost, low-power PIC16F17576 8-bit microcontrollers for analog sensors

Microchip PIC16F17576

Microchip PIC16F17576 8-bit MCUs are designed for low-cost and low-power analog sensors. They integrate a low-power comparator and voltage reference combination that can operate while the MCU core is in sleep mode, consuming less than 3.0 µA of current during analog measurements. The PIC16F17576 microcontrollers are equipped with up to four operational amplifiers (op amps) with software-controlled gain ladders, and a 12-bit differential ADC with automated averaging.

SATURN NITRO – A Microchip PIC32MK development board with Arduino Nano form factor

PIC32MK development board

While Microchip regularly releases PIC32 microcontrollers and evaluation kits, we don’t see that many PIC32 development boards from third parties. The SATURN NITRO is an exception, and the Arduino Nano-inspired development board is equipped with a 120 MHz PIC32MK general-purpose and motor control 32-bit MIPS microcontroller with 256KB SRAM, 1024KB flash, and 4KB EEPROM. The board closely follows the design of the official Arduino Nano board and can be seen as a beefed-up version with a much more powerful microcontroller delivering 198 DMIPS compared to the Microchip ATmega328P 8-bit microcontroller @ 16 MHz with just 2KB SRAM, 32 KB flash, and 1KB EEPROM, and a less capable I/Os.
