STMicro introduces cost-optimized STM32MP13 Cortex-A7 microprocessor

STMicroelectronics’ STM32MP13 1 GHz single-core Arm Cortex-A7 microprocessor series is the latest addition to the Linux-capable STM32MP1 family, with a cost-optimized design that does without the Cortex-M4 real-time core found in the original STM32MP15 series, while still offering Ethernet, CAN FD, camera and display depending on the specific SKU: STM32MP131, STTM32MP133, or STM32MP135. STM32MP131 The STM32MP131 is a single-core Cortex-A7 core clocked at 650 MHz or 1GHz with Ethernet connectivity and is the most cost-effective part of the new STM32MP13 series. Four parts are available in three different packet sizes (TGBGA 289, TFBGA 320, and LFBGA 289) as well as some parts with “advanced security features” that include a cryptographic accelerator, memory protections, code isolation mechanisms for runtime protection, functions to ensure platform authentication, and a complete security ecosystem. The STM32MP131 can run entry-level Linux, bare metal or RTOS systems with Microsoft Azure RTOS pre-integrated. STM32MP133 The STM32MP133 single-core Cortex-A7 […]

STMicro adds more STM32U5 Cortex-M33 MCUs with NeoChrom 2.5D GPU, 128KB to 4MB flash, NIST certification, etc…

STMicro has added three new families to its STM32U5 Cortex-M33 microcontroller series with the entry-level STM32U535/545 with as little as 128KB flash, the STM32U595/5A5 with up to 4MB of Flash and 2,514KB of RAM, and the STM32U599/5A9 with similar features as the STM32U595/5A5 by adding the new NeoChrom 2.5D GPU plus TFT-LCD and DSI display interfaces. STMicro also announced that STM32U5 series MCUs were the first general-purpose MCUs to receive NIST-embedded random-number entropy source certification. As of now, along with the STM32U575/585 introduced in February 2021 with an optional Chrom-ART 2D GPU, STMicro offers eight product lines as part of the STM32U5 MCU series as shown in the table below. That means the STM32U5 microcontroller can address a wider range of applications with the STM32U535/545 targetting lower-cost applications with less flash and RAM, the “legacy” STM32U575/U585 for mid-range applications, and the STM32U59X/5AX for applications where more storage and memory is […]

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 […]
